Hello there once again.

So since I reinstalled windows 8.1 with my new videocard i got from my local pc store because i am such a great customer(HD 7970 XFX Black edition 3GDDR5 or something)
my pc freezes after 15-20 minutes after windows loads.
I tried to reinstall amd drivers, catalyst control center, but nothing has fixed it.
It doesn't matter if i leave my pc idle, or playing(atleast trying) a game.
My videocard and cpu(FX 6350) aren't overclocked and my ram isn't either(some kingston 8gb ddr3 blu ram)
If my pc will start again, I'll try to post my dumpfiles.
(Currently I'm using my brother's laptop to post this).
Thanks in advance!

there might be a problem with your power supply [psu] because gtx 460 is not demanding card and your new card is !!!
