I'm not sure what the heck is going on but the monitor which is fairly new will not show a thing...They think it may be a virus...Urgh...Luckily I don't have too much digi stuff (it's on my EHD which I hope is safe)...
Gah, I'm sorry! Did you try checking the place where it hooks into the tower? My screen was bright yellow the other day on my brand new wide screen, and I freaked! Then I checked the back, it wasn't hooked up as tightly as it should be. I hope it's nothing serious!
