PC Hard Lock Up

[toluun]

I built a PC a couple months ago (see part list) and from time to time it will just completely lock up.  The screen freezes , no blue screen or auto restart, and I have no ability to use my mouse or keyboard.  The only way to return to normal operations is to do a hard reset by holding the the power button. I should note that the LED's & fans are still running even after the freeze.

 

It appears that the freeze most commonly occurs when the GPU is under load and I ALT-TAB to my browser.  However it will also occur when  the GPU is under load and no other programs are running in the background.  This freeze probably happens once a day or every other day.

 

I have tried a couple things to troubleshoot the problem  but had no success.

 

Things I have tried:

• I have been monitoring temps and both my GPU and CPU are around 40C when the freeze occurs.
• Ran a memory test overnight.  Returned no errors
• CPU Stress Test
• GPU Stress test
• BurnIn test
• Removed and Reinstalled graphics driver
• Updated Bios
• HDD Tests
• Removed HDD and ran everything off SSD
• Ran a quick check of my components to make sure my PSU was adequate. 

Do you guys have any  suggestions to troubleshoot the problem?

 

Thanks in Advance!

Welcome to the forums

 

Have a look in Event Viewer under the System logs. They should probably return critical errors and should show some details along with the errors.

Ok so looking through the event viewer I see the critical error is Kernel-Power 41 which to my knowledge is just saying that windows was shut down unexpectedly, which corresponds to me having to do a hard restart after ever lock up.  I then looked at System events around the time of the critical error.  I see an error EventLog 6008 which just states that the previous shutdown was unexpected.  There are no other events of note around the shutdown time. Is there any other place I should look in the event viewer?

Have a look in application. Doubt there will be anything, but you never know.

 

Have you tried using an older version of your graphics driver? If not, here is a link to the old drivers: http://support.amd.com/en-us/download/desktop/previous?os=Windows 7 - 64

 

You want the Crimson ones.

Did a quick check of application logs around time of the crash.  Still no errors or anything out of the ordinary.

 

I can give the old drivers a check, however this has been occurring over 3 months so I have tried multiple driver versions with no change.

Oh right. The only other thing I can suggest is move to a different OS and see if it does it on that. Still try downgrading drivers even further just incase.

 

If it does not work, then RMA your card.

If that does not work, RMA your PSU.

Try switching to microsoft's basic video driver for a while. I've encountered similar issues with my R9 and ultimately it was fixed by new drivers. If the problem disappears while you're on microsoft's driver you'll know what's the issue without the need of messing with your hardware.
