i just got a dell precision 390 and put a Geforce 7950GT in it for my gaming needs. sometimes after leaving the computer idle for like 12 hours i'll come back and my monitor will just show a sort of static but not quite as scrambled, with a lavender color to it. I can't get back to my desktop or anything but after pressing the power button the static stuff goes away and i see a blue scree (like the logoff screen) with no text before it reboots.
I have my tower in an office desk. could it be overheating and causing this? Anyone have any other suggestions i should try?
