Hey guys, I am new around here and I need some guidance. My pc has been overclocked for over a year and it was only about a week ago where I started to have issues, did not install anything new, only updates and what not. Here is my PC's spec's: Motherboard : Asus Maximum IV extreme-z CPU: I7 2600K 3.4 ghz (was at 4.6 stable for over a year) CPU Cooler: Notua NH-D14 Video Card: Radeon HD 6850 (have an alternate of HD 5770) Cosair vengence 2 4 gig sticks (low profile I believe) Anyway I cam home from work, my PC was on but died, no response from keyboard or mouse. Turned it off and turned it on, told me I "overclocked failed". So I put all of my bios settings to default and was able to boot into windows. Started to reseearch on possible problems, CPU, MoBo, Video card, RAM, HDD, and PSU. However, everything runs fine when NOT under load. I have ran, prime95 (crashes after 20 minutes it can take to almost an hour for it to crash). Ran memtest86, no errors to report there. If HDD failed then I wouldn't be able to boot, unless it was bad sectors. I took a screen shot of my bios and it looked like this. I don't like the wierd things on it, I cannot even see all the settings in the BIOS especially like that. I would add the crash dump files but its way too big. However i have attached what I got from WinDbg. I have tested with the other video card I have (Radeon HD 5770), everything appears to be all good however, my pc crashes after running anything. I am really running out of ideas. Any help is appreciated. Thanks.
