Windows 7: Computer Hard Freezes with No BSOD or Event Viewer Logs

23 Jul 2012   #1

Windows 7 Ultimate x64
Computer Hard Freezes with No BSOD or Event Viewer Logs

Howdy everyone. I've got a problem with my computer hard freezing (locking up, no input, have to perform a hard reboot) since July 15th. It seems impossible for me to diagnose this problem since I've never dealt with a recurring hard freeze before. My initial reaction was that the hardware was problematic, but at the same time I have no idea if it could be caused by a driver.

Attempted solutions so far:
Ran CHKDSK on both HDDs, no errors found (this is on a four-week old HDD with a fresh Windows 7 x64 install)
Ran Memtest+ for 7 hours, no errors found
Replaced the graphics card with a weaker one, problem still occurred
Constantly checking temps for overheating, card and processor rarely get above 40, but the computer still freezes during idle or low processing stages

Uninstalled, and swept video card drivers, then reinstalled twice
Ran Driver Verifier (as of now), and no blue screens
Started checking for any errors in Event Viewer (none are related to the crash so far, as I've fixed about 5 random things getting reported)
Checked for dump files, to no avail
Reinstalled all motherboard drivers from the manufacturer

At this point, I'm at the end of my ideas, so I came to you guys. I have no idea what information I could provide to you that may be of assistance. While the computer is frozen, it is still powered on as well - I have to turn it off manually, if that is revealing of anything. I'm basically willing to try anything. Please let me know if you have any suggestions... thanks!

Windows 10, Home Clean Install

Try in safe mode, if it freezes most likely hardware problem

Here are my solutions to freezing, and an excellent article, which I hope is of some help
Go to search type device manager and look for any yellow warning markers
Download and run malwarebytes, a full scan after you update
Run antivirus scan
Check memory with memtest86
Make sure that you are not over heating.
Try in safe mode; report back if it works properly.
Try a clean boot
Make sure PSU is working properly
If overclocking, restore to original
Test hard drive at company website.
Test in safe mode, does it still happen?
Try with clean boot..
