I started this build in December and the hang has been happening more and more frequently. When playing a game, BF3, in my case, everything works perfectly, CPU and GPU stays cool, I have the windows widgets and a readout on my keyboard that uses core temp to see live temps.
However, just watching a video on Youtube or browsing a site, or just listening to music, the system will freeze with the latest image on the screen and if sound was on, a .05 loop of the sound will keep playing. This happens at random times, nothing predictable, and I cannot replicate it. I cannot alt-tab, or ctrl-alt-delete out of it. Both keyboard and mouse go dead and the only way to break the freeze is to hit the reset or power button. On some occasions I will get a BSOD, but I think it has only happened 2-3 times, where as the hang has occurred at least 20+ times in the last month and a half.
Here are some of the things I have tried.
-Ran memtest86 for 14 hours: no errors
-Disabled on board audio in the bios
-Uninstalled Realtek drivers
-Updated Video card, and sound card drivers
-Ran ATItool scan for artifacts for 8 hours: none found
-Ran Prime95 for 4 hours: Stayed below 55C no errors.
-Messed with my power plans
-Enabled and disabled fast boot in the bios
-Ran full system scans with Avast, MS Security Essentials, Superantispyware, and Malwarebytes: nothing found but tracking cookies
I have done more but I cannot remember right now, will post when it comes back to me.
My next step is trying a new power supply, the 750W may not have enough juice, but I do not have one to test with currently. I am eying the 1200W x-series from Seasonic but I want to make sure it is not something else before I plunk more money down. I am willing to try any suggestions.
Thank you for your time and assistance, I have been very frustrated with this problem.
Edit: Forgot to add that this build originally started with a 96GB SSD which I had Win7 loaded on. I felt it was too small so I upgraded to the larger one. However when I had the smaller SSD installed the same symptoms were present.
