Computer crashes while playing games.

[dnemesis7]

I bought a computer from someone I knew and when I tried to test the computer by playing ARK, it crashed. I lowered the settings to low and it loaded the game finally. I played for about 6 or so minutes and it crashed again. So I tried Bioshock Infinite and the graphics were set to high and when I tried to load a save it crashed. I lowered it to medium and it loaded. While playing it I raised it to high and after a few minutes it crashed. I don't know what the problem is.

Change the PSU to one that's better quality, the one you have isn't good at all.

The one you have isn't for your type of PC and it's below requirements for the GPU.

You need a good quality 550W PSU Like:

Seasonic Focus Plus
EVGA G2 or G3
Corsair RMX.

Here is a EVGA G3 on sale:

OK, good.

I’m more inclined to think it's the graphics card dying out. How old is the R9 280 card your using? I slide in another graphics card to see first if it crashs.

 

[dnemesis7]

The guy I got it from said it was a year or 2 old.

The card wont be under warranty. Whats your budget for a new card?

 

[dnemesis7]

It's definitely going to be a little bit. I can't buy a card at this given time which sucks. But I was looking at around 250-400

Buy a 1060 geforce 6gb card for ($250-300). Good thing is prices are dropping on cards now again.

I might have to wait awhile for a new graphics card :/
