Pixel flickering/ freezing

[CharlieTango]

This evening I started up FS2004; within ten minutes a strange flickering pixelated look began rippling across the screen.

Sounds like it may me dodgey ram on the card or somthing??

Especially if its effecting your desktop too.  Though first thing to do is take off side of case and check the fan is spinning on the card when u turn on.  If its not then you might be lucky and just get away with replacing that.
