I've noticed that sometimes my video color quality changes from the highest 32 bit to medium 16 bit. And the screen resolution drops down to the lowest setting.
I run spybot regularly, a virus checker and have McAfee Firewall. |||You must update your driver
if it is a pc, open it while turned off, take the video card out and put it back in. close your pc.
if it is a laptop, you need to still update your video card driver and run it only on 1024x768, this is the setting most pcs run smoothly.
try this setting for awhile, if everything was ok then change it to one higher than this. if it changed back to lowest setting then you have to accepe the 1024x768 setting or take it to where you bought it from and say it is faulty or to suggest you new video card so it could be replaced.
Third option is to uninstall your video card driver and install it again, but you must have your driver cd or download it from internet.|||Might be drivers but make sure that you connected you monitor correctly ( if it's LCD you should be able to connect it directly to graphics card via DVI connection )
