My computer is less than 3 years old but I have been constantly getting this problem. I would be running a program and suddenly the display would freeze and i would have to restart the computer. Ctrl + alt + del had no effect. Upon restarting, the system would boot up but there would be no display or beeps. If i left it alone for months at a time it would start normally again, but sometimes I will get this line: Dram timing set too tight so reload. I have removed the video card and put it back in again but to no avail. Also I have tried removing both my rams but the problem still persists. Any help would be greatly appreciated as I do not want to wait for months to start my pc up again.
