Windows 7 64-bit custom PC freezing randomly every few days

freezewindows 7

Around May of this year, I built a computer using the following parts:

• Intel Core i7-3770K Quad-Core processor
• Corsair Vengeance 32GB (4x8GB) DDR3 1600 MHz memory
• MSI Radeon HD 7950 Twin Frozr III 880MHZ 3GB 1250MHZ graphics card
• SeaSonic S12II 520 Bronze 520W power supply
• Plextor 128GB SSD M5S 2.5 SATA
• Western Digital Caviar Black 1TB hard drive
• Gigabyte Z77X-UD3H ATX motherboard

Since building it, my computer has been running perfectly fine with no issues. Recently, however, in the past few weeks or so, it has begun freezing about once every 3 days, requiring a restart. These freezes are completely unpredictable, and can happen when I'm doing anything from browsing the web or playing a game, usually late at night or early in the morning. The screen will continue to display, howeve the mouse stops moving and the keyboard does not respond (caps lock light does not toggle on). The freezes also only seem to occur while I'm using the PC, since I have never found it this way after leaving it idle for hours at a time. Aside from the random freezing, the PC otherwise continues to run with no flaws or hiccups.

I have tried nearly everything I can think of to diagnose and resolve this, including running MemTest, stress tests for the graphics card, making sure all drivers are up to date, using multiple malware removal programs, and downloading a hotfix provided by Microsoft, but none of this has solved the problem.

This is what my Event Viewer looks like right now:

Anything to help resolve this would be appreciated, thanks.

EDIT 9/21/13: After reviewing the drivers again, I found that one of the VIA HD Audio drivers rolled back without me realizing it, due to a system restore I had to perform. I updated it a few days ago and the issue seems to be resolved for now. Thanks for the suggestions.

EDIT 10/12/13: It seemed to work fine for awhile, but the problem has come back and is worse than before. It crashes a few times a day now and I'm still having trouble finding the source of the problem.

EDIT 10/26/13: Managed to prevent any issues for about 10 days straight by leaving foobar2000 closed. Opened it up again and the computer froze within hours. Since the problem has been occurring before I started using foobar2000 instead of winamp, the computer seems to have issues with any music player, even when the playback is paused. Very weird.

EDIT 10/28/13: Froze without any media player open today. One thing I've noticed is that some of my USB devices (wacom tablet, network adapter) usually stop working before the freeze. No idea if that indicates anything important. Giving this solution a shot:

EDIT 11/6/13: The problem seems to be completely gone now. I took the advice from that Tom's Hardware thread and disabled "Legacy USB Support" on my motherboard's BIOS. (option seen here No crashes since. If anyone else with a Gigabyte motherboard is having similar issues, this is definitely something you should try.

There are many reasons for this so in regards to the Kernel-Power critical error you could review,

- turning off turbo boost or dynamic cpu adjustment (BIOS settings)  
- disabling SATA3 (BIOS settings - Most devices arn't SATA3 yet)  
- disabling HPET (BIOS setting - high precision event timer)  
- disabled ATI /AMD event logger (start/Run/services.msc Find the service and disable it)  
- updated drivers (Especially the audio drivers, some older versions of the HD audio can cause crashes)  
- disabled ATI RAID Xpert (start/Run/services.msc Find the service and disable it)  
- uninstalled ATI HD audio drivers (Right Click My Computer/Properties, click on device manager and uninstall drivers for HD Audio)  
- upping the northbridge and ram voltage by 1 or 2 notches (BIOS settings)   
- disable Harddrive Sleep and Hibernate (For Desktop users: In Power Options, select High Performance, Goto Advanced options, select Hard disk, and put 0 Minutes)  

I found that I had two C-Media sound drivers in conflict. My system continually recognized them as USB drivers when I had only one USB sound driver.

Disable Harddrive Sleep and Hibernate (For Desktop users: In Power Options, select High Performance, Goto Advanced options, select Hard disk, and put 0 Minutes)

Restore to the 'old' BIOS if recently updated.
