Crashing after 5 mins of gaming with black and white lines

[Draxarys]

I have had this computer for a while, it had its problems down the line but nothing too big just had to replace a fan or two. Couple days ago it started crashing and i had to force it close it was getting stuck. I checked the temps and video card idle temp was close to 70 So i called somebody and had it professionaly cleaned with blowers and stuff. The temp went down to 54 idle and i thought it was fine but i cant still play any game it crashes after 5 mins. My Card is Amd Radeon 7950 can it be somehow software related?

This is the HWmonitor stats after an hour of just browsing the internet.

What PSU are you using?

Looks like you are having a power issue. Check your psu and gpu, though I would check the gpu first. The hd 7900 series are known for having system crashes at the end of there life. At the same time your psu uses tier 6 components, really bad for gaming. Anything over tier 3 is prone to doped rails and bulged capacitors. The PSU is the one thing you don't want to go cheap with, it puts the whole system at risk.

How would i go about checking those things? is there a software that i can use for it? or do i have to find a new gpu and a psu and try to see which is gone bad.

This whole thing started by computer shutting down then not opening back up untill i cleaned the PSU, i'm sorry i forgot to mention that. Does this mean it's probably the PSU? My mind is all over the place right now sorry about that.

I set up the video card fans to 75% and its been half an hour and im still playing without any crashes. So the problem is more likely with PSU right?

It could very well be the PSU. The easiest way to test it would be to swap it out. Or you have the experience you could test it with a multimeter. But that can be dangerous if you don't have the know how. A psu swap is fast, and if it not the problem, you can always return the new psu.

Though if i were you I would change out that PSU either way. Tier 6 are not stable psus, especially under load

Allright i'm gonna focus on a new PSU, is there something you can recommend that is not too expensive and reasonibly good. My PSU is under warranty for couple more months i think i'm gonna send it and see if i can get a refund or store credit. Thank you.

The EVGA SuperNOVA 650 G1, 80+ GOLD can be had for under 100$. And comes with a 10 year warranty. Also checkout this thread http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html a bit old but still good
