Crashing Issue

[toggleguy]

My friend is having issues with his pc, in that it crashes seemingly randomly (usually when under some sort of load), and fails to post after playing a game.

His specs:

i5 4690

msi B85M - g43 motherboard

corsair cx600 psu

2x 2 4gig memory sticks (1866mhz)

evga gtx 970

He has concluded that whatever the memory configuration, the computer doesnt post after playing a game. He has had many problems with this pc before and has RMA'd every component with scan, other than the gtx 970. None of the parts have ever been overclocked. We are struggling to troubleshoot the problem and make the computer stable. Anyone got any ideas? Im feeling that its a problem with the motherboard, but not sure.

Was the OS upgraded or clean installed?

Firstly, if you can get some error codes or memory dumps from Event Viewer, it could help to find the cause.

 

I've experienced a lot of problems with upgrades.  It always seems like the drivers don't translate correctly or something of that nature, that's why I asked.  If you can, try a clean install with fresh drivers.

 

I usually go after hardware as a last resort, but I've heard bad things about that particular PSU.  If it comes that point, I would test the system with a different PSU if you can.

Hey, I'm the friend he's on about,So I fresh installed win 7, during a driver installation it required a restart, it then restarted and didn't post. I forcefully shut it down and it then posted but completely ignoring the 970 and sending the monitor output through the mobo

 

I don't know what to do, thanks

 

Unplugging the 12 pin connector to the 970 and putting it back in causes output through the 970
