Display appears only after several hours of waiting
try plugging your monitor into another computer, if it works, plug your computer into a different monitor......if it works its a compatibility issue....if the new monitor doesnt work then its your video card, and if your monitor doesnt work on another system them you have a failure within the vga (or which ever you use) adapter itself on the monitor.
GOOD LUCK AND PLS RATE THIS POST!!!!
