This just started yesterday but my computer crashed and when i tried to start it back up it would freeze as soon as the desktop came up. I reinstalled windows 7 and i was able to get to the desktop but if i openned a program it would crash, no bsod, sometimes as a solid color on the screen, other times with squiggly colored lines. I ran memtest for 12 hours with no fails, took out each stick of ram individually with the same results. Then i partitioned space on one of my other hard drives and did another installation of window with the same results. I took out all the necessary components like my sound card and still no change. Finally did a fresh install of ubuntu to see if it would do it as well and it would when i tried to click on the dash home. I updated my gpu driver on both systems but i suspect that the gpu is still the culprit. I was hoping to get some insight on here before i make a purchase.
