Hey guys, I keep randomly having computer freezes every so often when i'm gaming, on the Internet or just on the desktop. It is really frustrating and annoying, it either just goes to a blank screen forever until i reboot computer or it BSOD randomly. I tried re-formating my computer twice and it still had same problem and ran everything at stock settings and still no luck. And sometimes when I turn on my computer, the boot-up screen all the way to windows 7 has like massive lines everywhere all over the screen like its artifcating, but my temps are extremely fine, cause i boot the next day following. And when gaming, it randomly just freezes the whole computer and no bsod or anything so i have to restart. Is this my HDD? I don't know what's going on, it can't be any of my components because they run everything fine and nothing suspicious about them cheers.
