Hey guys, hoping someone might have a moment to help me track down the root of this issue. Over the course of the past three months, my computer hard locks(typically looping the last couple seconds of audio though not always) an average of twice a week. I have tried to track down the issue, initially blaming the fan controller on my video card, but so far, I have not been able to discover the root cause. Any ideas you can suggest would be greatly appreciated.

Any ideas? I can't answer much while at work(eastern time zone) but I will do all I can to provide any information that might help track this issue down. Thanks for any follow up you might be able to provide.
System Info:
- CPU- Pentium Dual Core E5200 Wolfdale
- MotherBoard- Gigabyte ep45-UD3LR flashed to Latest version of Bios
- Video Card- Radeon HD 5830
- Power Supply-XFX XXX edition 650 watt (xfx are rebranded sea sonic power supplies)
- Memory- 4 gigs g-skill
- Sound -1 x Creative 70SB073A00000 7.1 Channels PCI Interface Sound Blaster X-Fi XtremeGamer
- Cooling- case is Cooler Master HAF92. Cpu cooler is a xigmatek design.
- The system is not currently overclocked in anyway.
- Bios settings are set to safe(default) settings.
- Operating system = Windows 7 x64
- Currently five internal Harddrives, two of which are broken into two partitions.
Lock up occurrences:
- All but two lock ups have occurred while playing one particular game(diablo 3 blizzard entertainment). If you Google hard lock along with the game you will get hits, but that is somewhat expected with the game selling over 10 million. I have the issue twice outside of the game so I don't believe the game is the sole fault.
- 1 lock up occurred while streaming a tv show off of hulu.com
- 1 lock up occurred in an OCCT power supply test(this occurred after I swapped video cards, as detailed below, and once I returned to my video card, the test can run for an hour without issue).
Test Info:
- I can run OCCT CPU, GPU, Powersupply one hour large data set stress test without issue. Is there any benefit to running a test longer and/or using small/mid data sets?
- Intel CPU tester passes all tests
- I can run superpi to 64M decimals 32 reps without issue.
- Virus, Malware scans all comeback clean.
- The thermal sensors on my cpu are stuck at 57 but kick in once the cores exceed this temp, during the stress tests the highest they reach is 61* C
- Video card with speed fan used to set the GPU fan to 100% never goes above 59* C. Without speedfan controlling the fan the GPU only hits 90*.
- There are no minidump files(I would assume due to the hard lock and not a crash
- System logs only record event 41 unexpected system shut down, again I didn't expect anything useful due to the hardlock and not a crash.
Steps taken:
- I used speedfan as initially I noticed the gpu fan never speeding up and I thought it might handle heat poorly. I set the gpu fan to 100% which lowered the temp from 90* full load to 58 full load without overheating any other part of my system(speedfan reports all harddrives around 32* cpu below the stuck threshold of 57*). Issue remains and I don't believe 90* full load is killer.
- I swapped out my video card for a Nvidia 8800gt. Completely removed all ati drivers and apps and installed updated Nvidia drivers. Less power draw+ other company. Issue remained and with this card the occt powersupply test caused a hard lock in about 27 mins. I have since swapped back to my ati card and all occt tests complete without issue.
- At this point, I was looking at my sound card, as creative doesn't have the best rep for their drivers. I have a copy of windows 7 x32 lying around so I did a clean install of it, on a clean drive, as a duel boot option. The only thing I installed in this installation of windows was the newest ati video driver(driver only, no catalyst control center, no hdmi audio drivers). The issue seemed fixed, four days without issue, until today when I once again hit a hard lock while playing diablo 3. This would seem to rule out any software, most driver conflicts as it was a clean install of windows. I did point to the existing install of diablo 3 rather than doing a clean install of the game.
