New PC is going black?

[Weegee]

So, I've built this new computer for my cousin. It runs games great usually, but now, after 6 days of working with it, in the middle of gaming sessions, the thing half shuts down randomly.

The monitor loses connection and he goes off of Steam...but his computer still seems to be on. His fans are blowing, both his GPU and CPU. his power light is still on.

 

This has happened twice. The first time he lost over 20 hours on borderlands 2.

The second didn't do much.

 

THIS is his build

 

Thanks

EDIT: i was wrong its the lower psu that makes shutdowns

The PSU is fine. 600W should be ample power capability for the parts.

Agreed. We'll need temps to see what's going on here.

im getting the temps

 

EDIT-------

 

so, its happening even we're not doing games.

Temps idle around 38degrees cel, and so do mine. We're at a LAN in the middle of the summer. So thats normal

Alright, that's weird. 

 

Can you find anything in the windows event log at all?

 

Do you have time to test the RAM? see if that finds any errors.

Also try reseating all the components and cables/plugs just to be sure.

It still could be the PSU. 600 watts might be ample but if it's faulty it can still cause these kinds of dropouts. But the VGA could be doing this, too, so check GPU temps as well.

RAM is tested. good. See below for more.

So, for everyone, it turned out to be the GPU. We took it out and ran some benchmarks (on integrated graphics) and it never once went black.

 

I'm working with newegg to RMA it for a refund so we can get a better card.
