Maybe someone has a tip that will solve my problem: I flashed the mobo and vid card BIOS and have tried several Nvidia Det drivers but am still having problems. STRANGE problems! My computer seems to lock up or the screen goes screwy at the initial Windows XP Pro boot up screen (the one with the progress bar). The screen usually blinks a few times then goes all screwy. Then I need to reboot a few times or go into safe mode then it seems ok. However, the problem only seems to arise when the computer has been sitting (off) for a few hours or more! Once i get it running, i can reboot a hundred times with no problem. BUT, then the next morning, it goes screwy again. I am so stumped and frustrated. I dont have another DVI card to try, so what can i do??? Are there specific motherboard BIOS serttings i should be looking at? I dont want to have to return this beautiful monitor! HELP ME. It owrks fine with Win2000! Thanks for any help.
