Ok so I need some help.

I've tried over clocking my CPU through the mother board and OverDrive and to little success. But the weirdest thing happens when I use overdrive, it effects my gpu so much that it cant play games.

I used overdrive to see how far my cpu could go and it got up to 4.5 before crashing. but for some reason when I put it over 3.4 my gpu just stops working properly.

Could this be a bad gpu or cpu? I'm not really sure how to go about overclocking properly.

I've switched to an i7-4790k and everything seems to have been resolved.
