what would cause a computer to crash with no blue screen

fst89lx · Jul 25, 2019

In the past 7 days, my pc has randomly crashed twice. Both times I was just watching a stream on twitch, the pc froze, audio gave a loud bzzzzzzzzzz and the screen went blackness. The get-go fourth dimension, the screen stayed blackness, no audio from speakers, mouse and chiliad/b lights dead, but motherboard showed qcode b2 and had a white LED illuminated (next to that LED says VGA). I had to reboot the organisation westward/ the ability button and its been all fine since then, until today. About 10 minutes agone, the exact aforementioned thing happened, except right after the screen froze and the audio buzzed, the pc rebooted itself unremarkably. No qcode.

Neither times did I get a blueish screen. In my transmission, qcode b2 is - Legacy option ROM initialization.

a quick search brings this response in the asus rog forum from an asus service rep:
The B2 usually means Legacy ROM has an error or Graphic card problem
Try to remove the Sapphire Radeon 7850 or switch the iGPU , Allow united states know if this helps.

What is Legacy ROM?

Where should I go from here to test things to run into what the problem is? Is there any other info yous guys demand that could aid?

Arrangement is 8086k, maximus ten hero motherboard, 16gb trident z ram, gtx 1070.

Give thanks you!

*edit* Wanted to add that this system was built in ~ September of 2018 and has really had 0 issues so far, no new hardware has been installed either.

TheFlayedMan

Is at that place a newer bios for your motherboard available? Is at that place anything in the windows event viewer relating to the crash? Crazy heat wave here could it be temperature related? Does the graphics menu run benchmarks ok?

fst89lx · Jul 25, 2019

Aye there is a new bios update. Event viewer shows one critical fault in the final 24 hours. Event id 41 kernal-power. Full general clarification tab for that says "The system has rebooted without cleanly shutting down commencement. This error could be caused if the arrangement stopped responding, crashed, or lost power unexpectedly."

aforementioned error happened for the first crash as well.

I take cardinal AC and the house is always at 68-71* F

I am not opposed to updating my bios, but why all of the sudden would this start to happen with no hardware changes being washed?

I'one thousand also on windows ten ver 1803. Not really sure if that is up to appointment or not. Guess I'll run windows update and meet.

I'one thousand thinking I should stress the arrangement... Maybe run a gpu criterion for a while (I accept heaven), run P95, run memtest, etc. Good idea? waste of time?

fst89lx

Just had another crash. Was gaming this time. No motherboard code, no windows message. Audio bzzzzzz, blackness screen pc restart.

One of the guys I game w/ said it sounds similar a bad gpu, because he had the same issues in the past... That is also what the asus tech said to a higher place regarding the motherboard code I did go the get-go time. Where to go now? I take updated windows, and my audio drivers today. I can update my bios, merely I'd rather not honestly, I don't see why a perfectly stable system would become unstable and require a bios update.

I unfortunately don't have a second gpu that I tin throw in and exam for a few days/week.

DrLobotomy

Perchance a ability supply upshot.

fst89lx

How can I go most testing these things? All that comes to heed is stress test each component like I mentioned above and attempt to induce a crash...

TheFlayedMan · Jul 25, 2019

The motherboard code is where I got the bios thing from a google search on the error message. Sounds similar a faulty GPU or PSU though but hard to say for sure without swapping out parts. I'd probably exercise a fresh install of the Bone first simply to rule out software effect and then replace the GPU, then PSU.

If you can borrow a GPU or buy one from a store that has a dainty return policy that would be ideal.

DrLobotomy

Get purchase a new PSU and run into if issue goes abroad. If it doesn't so have it dorsum and buy a GPU etc.

fst89lx

Well that sucks, feels kinda scummy doing that.

DrLobotomy

No one says you lot Have to accept it dorsum. A spare PSU always comes in handy and you can get-go a second build for a server and use it for testing parts when needed.

primetime

In my experience these restarts are retention or power supply related 99% of the time....Since your instability came out of know where im more inclined to think its power supply related. Memory is ordinarily stable or its non in most cases/
What is the exact name and make and model of the supply being used?
Also run some stress tests that max out ability consumption...ITs should restart or turn off pretty quick if its the power supply.

What is the verbal proper noun and make and model of the supply being used?
As well run some stress tests that max out power consumption...ITs should restart or plough off pretty quick if its the ability supply.

Power supply is EVGA supernova g3 750.
Ran unigine heaven for near 35-twoscore minutes terminal night, no crashing, gpu temp got up to 66* (gets up to 68* gaming but I assume the added oestrus from the cpu being dumped into the example causes that)
Ran prime95 newest version large FFT for 5 and a half hours terminal night, no crashes.
Ran prime95 newest version Small FFT for half an hour this morning no crashes

Gonna allow memtest run while I am at piece of work and cheque when I get domicile today. I'll report its findings afterwards.

how would I max out power consumption? Run heaven and prime95 together?

DrLobotomy I understand what you're maxim, and I may in fact have to purchase parts and merely swap them out to test, simply I'thousand keeping that to a last resort. I utilise this pc for xc% gaming and web browsing, volition never take a second build or a server, etc. The plan is to run this setup until the hardware is inadequate for what I want to practise, then either overclock to squeeze a fiddling more usefulness out of it, or just build a new one and echo. Money is somewhat of an issue likewise. I've got the coin to spend, but it would be better served for other things right at present.

Thank you for the suggestions so far, I'll let y'all know what happens w/ memtest. Then I guess I'll re-install windows, update the vga commuter and bios for the mobo, and get from at that place.

Overheating, overclocked organization, bad windows or software update?

fst89lx

Overheating, overclocked system, bad windows or software update?

Don't think it is overheating. P95 newest version that I ran this morning small fft (avx on) got up to 75* large fft ran overnight stayed beneath seventy* iirc. Every time I've checked temps while gaming I am in mid sixty's.

Gpu gets to mid/high 60's while benching/gaming.

No Overclocks at all. Ram is a 3200 kit running at 3200 (manually entered xmp timings because xmp on my board wouldn't work properly). System has been like this since last sept.

Not sure about bad software, I would think I would get a blueish screen or some sort of mistake message and not just a hard reboot, but re installing Windows is on the list.

Ran mem examination this morning, system hung like 3 minutes in.... Was frustrated and just pressing keys trying to go it to reboot, esc, c(config in memtest) and Ctrl alt del. Not sure which did it, but it rebooted and began memtest over again, was at 17 min when I left for work.

TheFlayedMan · Jul 26, 2019

Perhaps information technology is memory instability then. Try bumping up the voltage to the memory past a little. Yous could gear up the ram to 2666Mhz as this is the fastest officially supported speed.

fst89lx

Mayhap information technology is memory instability then. Effort bumping up the voltage to the retentiveness by a petty. You lot could prepare the ram to 2666Mhz as this is the fastest officially supported speed.

Yea, maybe. Curious to see if memtest is still running at present after I restarted information technology and left for work.
I can put ram back to stock and see what happens. Gonna be a chip bummed if the sticks are going bad since I paid for the 3200 MHz kit.

if that is the effect, wonder if the sticks are covered at all by gskill, or is xmp speeds non guaranteed...?

I did have ram problems in my last PC but I would just go program crashes and error messages in Windows, no system crashes (i5 2500k Windows seven on that machibe if information technology matters)

TheFlayedMan

It's too possible that the latest bios for your motherboard volition have improved retentiveness compatibility.

pendragon1

what gpu are y'all using? ive seen several people talking virtually problems with the newest nvidia drivers.
and I agree with the psu proposition, starting time at that place then expect at gpu. actually, practice the bios update first.

fst89lx

But got home and checked pc. Memtest completed with 0 errors. Likewise when it hung on memtest earlier today, at that place were no errors at that time. The whole affair was just frozen.

I am using a evga gtx 1070 ftw. I had been using the same driver for quite some time up until last friday when I had the commencement crash. After that first crash, I updated my driver.

So far what I accept left to try are: Updage vga driver from asus website, set ram to default speed, re-install windows, update bios, swap parts. In my mind, I would like to exercise them in that gild. I desire to do bios concluding considering in my mind it isnt a bios consequence. Why would my current bios suddenly take a problem 9+ months later on a completely stable arrangement? I am willing to practise it, don't get me wrong, simply doesn't make sense.

Is there any harm in running heaven and p95 together to cause higher power draw from the psu to try and examination that?

pendragon1

Updage vga commuter from asus website,

nope, employ the 1 from nvidia but become back a version.

Why would my current bios suddenly accept a problem ix+ months later on a completely stable organisation?

windows updates... i'd practice the update.

Is there any harm in running heaven and p95 together to crusade higher power draw from the psu to endeavour and test that?

nope

TheFlayedMan

I know I suggested re-installing WIndows but it doesn't sound similar a software trouble. I call up I'yard conditioned to suggest it from when I worked for a computer company the policy was no RMA'south unless the organisation had been restored first lol It'due south not a bad thought before spending coin to exercise it (depending on how much time/money you lot have lol) only I'm thinking PSU now.

fst89lx · Jul 26, 2019

nope, use the 1 from nvidia simply go back a version.
I'll try it. Tin you tell me though, what is the "intel VGA driver" from asus for? I've never updated that as far as I can remember. Is that for if I am using the iGPU on my processor?

windows updates... i'd practice the update.

Ok, I'll effort information technology tonight. I need to make sure that I recollect what I had my VCCSA and VCCIO voltages set to, there is a guy on the rog forum proverb that the new bios set his to something crazy like 1.4v, mine are at similar 1.14-i.xix or something.
nope

fst89lx

I go it human being, it is funny to me that I come across soooooooo many times people become suggested to re-install windows to try and fix things, I remember that I had my last pc since like 2011 or 2012 up until I built this one last twelvemonth, and I never one time re-installed windows to prepare something. Except when my HDD took a shit, then I kinda had to. I really think it'south a hardware issue not a software issue simply because of the lack of error letters. I volition however be the first to admit that I am nowhere near knowledgeable enough to say that with whatsoever certainty.

pendragon1

"Is that for if I am using the iGPU on my processor?" yup

fst89lx

Before long afterwards I read pendragon1 latest reply, I downloaded latest bios and dug out a flash drive. I formatted the drive and the second it finished, the arrangement crashed lol. Exact same thing as the first crash I had final week except there was no buzzzzzz/audio stutter because I was not watching a video or listening to a stream. This time the b2 code was back and white vga led on motherboard was lit. Organisation was unresponsive until I re-booted with power push button. After that it booted right into windows. Figured before I update this bios, I'd run p95 and heaven together to go the most power describe and rut I could. Ran p95 modest FFT due west/ avx and unigine heaven together for 30 min and here is the outcome:

NO CRASH....
CPU max temp 79* on core two
CPU package ability 126 watts
GPU max temp 66*
GPU max power 155watts

I'll revert my nvidia commuter and update my bios when I get back.
I practise accept some other question, I am actually kinda nervous to update windows if the bios/driver don't fix anything because I'thousand worried the system will power off in the centre of the windows install..... Obviously that will corrupt the install right? Will I still be able to boot w/ the media creation tool and format the drive and try again or would I be screwed?

Thanks guys, appreciate all the aid and then far!

I exercise have some other question, I am actually kinda nervous to update windows if the bios/driver don't fix annihilation because I'thousand worried the organization will power off in the centre of the windows install.....

no dont do windows updates. I meant that they might have introduced the problem. the newest windows update needs the latest bios and newer drivers to avoid problems, possibly like your state of affairs.

fst89lx

no dont do windows updates. I meant that they might have introduced the problem. the newest windows update needs the latest bios and newer drivers to avoid issues, peradventure like your situation.

Roger!

Got the bios updated. On Asus 2102 now. Have not reverted to an earlier nvidia commuter yet. Going to see if this crashes. When/if it does, I'll curlicue back the nvidia commuter.

Only updated bios a handful of times earlier, damn thats a scary procedure! Used the bios flashback port on the dorsum of the motherboard to flash. First go round, I had my wink bulldoze formatted to FAT and the update didn't work, luckily I didn't F anything upward, got back to windows, reformatted to FAT32 and that did the play a trick on. Then all the goddamn restarts after the flash is consummate. Eye was in my tummy the whole time lol.

So anyway I'll permit this thing curl for a while and meet how everything goes. I definitely need to reset my fan profiles, they're going basics every fourth dimension I launch anything, up an down, up and down.

fst89lx

Haven't gotten a crash since the bios update on Friday. Hoping that has fixed it! Going to give it a few more than days and have the ram dorsum upwardly to 3200. Give thanks anybody for the suggestions and help!

fst89lx

Put ram back on XMP this forenoon. Something to note, the new bios does seem to operate a little bit different from the bios I was running earlier. When I first build this system, I couldn't use XMP. Instead I had to enter the ram voltage/timing manually because enabling XMP made the system do weird things, see post hither-----> https://hardforum.com/threads/enabl...it-and-throttle-down.1968366/#post-1043845054

This time around, XMP seems to work just fine except like in the final bios, the board cranked VCCIO to like 1.32. I put that down to 1.15v in bios, (shows anywhere from 1.176 to 1.184 in HWinfo). Later I run this for a few days to ensure it is stable, I might take that down ane more step.

fst89lx

Crashed again just a minute agone. Estimate all I tin do is get out XMP off. Worried that since the ram passed memtest, that the retentivity controller on the cpu is weak/dying

TheFlayedMan

Need to find the fastest stable ram settings. Or but stick to 2666Mhz

fst89lx

sick probably just stick to standard speed.

Is at that place anyway that the ram itself could still be the upshot, or is it more likely that The cpu memory controller or motherboard is to blame?

fst89lx

So, I am at a total loss at present. Pc just crashed over again. Same shit, no error message, simply rebooted it self out of the blue.

TheFlayedMan

What power supply do you take in the system?

fst89lx

Evga g3 750 watt, bought new when I built the arrangement (terminal September)
I put in a support ticket w/ evga for my video menu to run into if I can RMA it. The merely clue I've gotten is the damn VGA light being lit on my mobo sometimes when the whole affair crashes/re-boots. Simply it'due south been suggested that it's GPU related, and my carte has a lot of roll whine, and lastly one of the fans will spin super slow at idle while the other one is still. Guess I'll offset there if they'll rma my card.

TheFlayedMan

I would guess rebooting is power supply related as information technology what happens when the OCP gets tripped.

fst89lx

Yea, that'south side by side on the list afterwards I run into how the rma on gpu goes.

Not sure what evga is gonna say if I endeavor to rma the power supply after the gpu, but I'll give it a whirl if the gpu doesn't fix it.

fst89lx

And then tonight, I had two more weird things happen. Start, I was on youtube and twitch, my screen went black for a couple seconds, then came back and both areas where video would be playing were green. They fixed themselves with a reload of the folio. Next, I was playing pubg and alt--tabbed to picket back a clip and the video froze on my screen. I could all the same see my mouse cursor moving, and hear the game/discord merely the keyboard didn't seem responsive, and the guys in discord could not hear me when I spoke. Had to re start w/ power push button.

Making me lean a lot more towards the GPU now. Need to hear back from EVGA on that withal.

It's either 1 of 2 things, your GPU is bad or the power rail in your PSU that supplies PCI-E power to the GPU is failing.

Try running OCCT PSU stress test, this (IMHO) is better and more than informative than running P95 and a Unigine production concurrently. But make sure if you lot're running the GPU stress exam in windowed way you click ON the "fur donut" so it stresses the GPU (you'll see what I hateful).

Also y'all can purchase a pretty cheap PSU tester on amazon.

OhSigmaChi

As well, peradventure pull the GPU and accident it out with some canned air. Mayhap change the thermal paste.
