HELP! PC Keeps Shutting Down

[Leese154]

Hi Guys and Gals,

 

So over the last few months I've been having a serious issue with my PC and can't seem to isolate the issue.

 

Basically, my PC shuts down (completely looses power) without warning or BSOD after 30 minutes of being on. I have check windows event viewer and couldn't see anything out of the ordinary

 

I've run various tests on individual components with no luck.

 

Any help or advice would be much appreciated. 

 

So far I have:

• Replaced the PSU
• Stress tested CPU, GPU and Ram. Programs used, Furmark, OCCT and Mem Test (Temps were in a normal range)
• Tested PC withiout GPU, using built in MoBo graphics
• Left running in Bios mode
• Replaced Cmos Battery

I know I probably haven't done as much as the average nerd would but I'm still fairly new to the custom build world.

 

Specs:

 

GPU: Gigabyte GV-N760OC-4GD

CPU: Intel 4770K

PSU: 650W Cooler Master V-Series 650S Gold

MoBo: Asus Maximus VI Impact

Cooling: Cooler Master Seidon 120XL Water Cooling Kit

RAM: 2x4GB G.SKILL Ripjaws 1600MHz DDR3 Ram

Did you make sure everything is plugged in correctly?

My computer shut off a lot, it took me hours to release that my motherboard plug was loose.

Have you tried turning it on and off again?

I had a problem with a corrupt hdd.  My computer started shutting off randomly, it was rare at first but then it began to shut off so frequently that my computer was unusable.
