HELP. BOOT UP PROBLEM!

Novokuv · 20 Sep 2013 at 23:06

I was starting up League of Legends match and then my PC freaked out. I couldn't shut it down or anything so I took out the power cable, I booted it up and these random lines appear on my screen. I just recently built my PC and I do not know what this is. If anyone knows then help me urgently!!!!

This is what happens, first it is booting normally and after a while lines appear and then when it goes to the welcome screen it doesn't change and after the awhile on the welcome screen, the screen changes all blue and doesn't display any message at all. I need help ASAP, I don't want m £600 to go to waste.

It seemed that that was the only way to power off it, I tried many ways but I had no success in it.

I get this flashing thing when I am gaming, it happens after playing for 5 minutes, I reinstalled my graphics card drivers but it has no effect.
