I recently built i new pc for myself and after two or three weeks it started randomly shutting down while gaming. So i went into the event viewer and i got this error "6008 The system shutdown at *** on **** was unexpected. Specs: Motherboard: Asrock z68 Extreme4 CPU- Intel i5 Sandy bridge 3.2 ghz SSD- Ocz agility 120 gb GPU- Gts 450 PSU- Coolermaster 600w RAM- 2x4 gb Gskill Ripsaw Series OS- Windows 7 home premium x64 As for trouble shooting i have formatted my hard drive and done a new install of windows 7 home premium x64. I have completly updated all drivers to newest version. I have removed my GPU to see if my PSU was inadequate. I have removed my optical drive. I have ran occpt to see if my cpu was overheating it hit 70C before i stopped the test my temps get no where near there when gaming. I have ran disk check memory check no errors virus scans no viruses, umm. MY pc is not overclocked. Pretty much u name it ive done it. SO this is a huge problem for me and i need help. So i just ran furmark to stress test my GPU and PSU and the second i hit start my pc shut down. SO im more than positive ive narrowed it down.
