my computer has been restarting randomly for months now. i7 3.2, 8g ram, GTX570, Windows 8.
It is not a overheating issue or a power supply issue, ran memtest86+ and it passed 7 tests so I don't think its RAM issue either. Machine is not dusty inside case. Run high end games on ultra settings (GW2, Skyrim, Battlefield 3, Planetside 2) and never have issues. Restart seems to happen while viewing photos, surfing net or using Photoshop. Leads me to believe it is not a graphics card issue (also card doesn't come close to overheating while in games).
Virus scans all come up clean. Please help, no idea how to fix this! Thank you in advance.
