Recently Built Gaming pc having issues...

OK so recently I built me very first PC for gaming I will list the link to the parts at the bottom.Anyways whenever I play Alien:Isolation or Metro Last light my monitor does these weird colors for half a second then turns off completely black.Now I know its something wrong with the PC because when this happens the monitor still is on and the PC is still on so its the actual PC that's the problem.I have tried to do numerous things to fix but no have worked.Lived reinstalled the driver,made sure everything was tightly secured,took the card out and put it back in and none have worked.However reinstalling the drivers Gave me a bit more time then it regularly happens(usually happens 5 or 4 times in a period of a 1 in metro last light).
Any help or suggestions will be appreciated thank you.

Edit 2:I almost forgot to mention that when I was assembling the CPU I left the processer out to long I think because it dried up a little but not a lot.Ived been checking the temp and is at a average of 90 f to 100f or less.Would this be causing the problem or at least contributing to it?

The first thing I would do is clean off the cpu and the heatsink with isopropyl alcohol and then reapply paste. I only use Arctic Silver.
If that doesn't do it rep[lace the psu. That Corsair Psu is junk I'm afraid made by CWT a low end maker. I would suggest an XFX or Seasonic psu of at least 550 watts.

 

I would second to checking on that power supply.

 

I would not say the Corsair CX line is junk or trash I would say it's not as good as what a Seasonic unit will give you. For an R9 270x you would want a CX 600, or better yet for optimal performance and clean power you could get a Seasonic 620W.

 

Forgive me from saying "junk" please it is not junk, it is just for ordinary use and not gaming is all.

 

You can use it for gaming. Tens of thousands do, it's just better to get a Seasonic for that job. It's likely going to last longer, and the voltages should be more accurate with less ripple and variances of voltage output and a cleaner overall power delivery. on a scale of 1-5 with 5 being the best obviously the Seasonic would be a 5. A Corsair CX would be a 3 possibly a 2 at times, and though the Seasonic would be a 5 there are times it's a 4 they have failures and units that are not as calibrated as they should be but that goes with any electronic piece of equipment.

 

Another nice thing about the Seasonics is the Corsair gives you a 2 or 3 year warranty where the Seasonic gives you 5. That means something.

 

It sure does! Peace of mind with better quality hardware and a better warranty.
