HELP ME PLEASE! RANDOM SHUTDOWNS

[Traycasher]

alright so here the problem

 

PROBLEM

-during light usage PC will shutdown but not like a normal shutdown but instead, where my screen goes blank with just the backlight remaining on.

 

-by light usage i mean such as browsing the web, looking at steam, or just randomly while on my desktop or in the windows menus.

 

WHAT I HAVE TRIED

-at first i thought it was the power supply but the computer remains on with all my fans and everything on but the screen just goes out, and its not the monitor.

 

-second i thought it was the RAM i did a MEMtest and the RAM is fine.

 

-third i thought it mightbe the motherboard so i updated the BIOS and still nothing happened. 

 

-fourth i checked the DRAM voltage and havent lowered yet but will be soon(haswell-refresh reccomended is 1.5V im at 1.65V i think)

 

-fifth i thought it was software so i updated to windows 10 just to get rid of any files that may be weird or whatever in windows 8.1

 

-sixth well i got no other ideas.

Are you using Windows 10? Windows 10 does this a lot but eventually repairs itself. Just let it crash.

It happens sometimes to my computer as the ATX pin is not seated properly in the motherboard, but as some pins are still touching, some of my fans and LEDS turn on.

[Traycasher]

yes im on windows10 but it happened in 8.1 as well and i have also reseated all my plugs but thank you for the suggestion

If you have AMD crimson installed, try uninstalling that and see if that fixes it. Had the same issue with mine.

[Traycasher]

i do not have that installed
