[B]Video card:[/B] 256MB ATI RAdeon X1300 Pro PCI Express Graphics Card [B]Monitor:[/B] Dell 2007WFP LCD Monitor [B]What doesn't work[/B] Has worked great since I got the monitor a couple of months ago but this morning when I started up I get to the blue welcome screen then after around 10 seconds it all goes black - though the login music sounds and the disk sounds like it's all running as normal I just can't see anything (cursor included). I use Zone Alarm Security Suite and it completed a system scan yesterday, while updating the anti virus it said that any changes would take effect the next time I started up which was this morning. [B]What does work[/B] I'm able to get to my desktop via safe mode and I've downloaded the latest drivers for the monitor but I can't update the drivers because the Properties option under Settings->Advanced->Monitor is greyed out. I'm also able to get to the desktop via VGA mode and using a VGA cable though the monitor settings are greyed out here also. [B]What have you tried[/B] I've also tried removing and replacing the graphics card and restarted to the last known good configuration to no effect. Totally stumped as to what to do next, the setup's worked fine for a couple of months now so strange that it would stop now. Thanks in advance for any help and suggestions.

No worries folks, got it fixed. For anyone else with the same problem here's how it got fixed... Boot into safe mode, go to control panel, system, hardware and open device manager. Remove all the display adapters. Restarted and downloaded the latest drivers from Radeon site.

I'm having the exact same problem, only with a nVidia card. It runs fine in safe mode, but a normal boot blacks out at the logon screen. I've tried the suggestion above, as well as everything I could find on the net. I've tried four different driver versions from the nVidia site, with the same results every time. According to the event viewer, "The driver nv4_disp for the display device \Device \Video0 got stuck in an infinite loop". The card gives me no problems under Linux, Windows XP - Safe Mode, or when booting from a DOS CD. This would indicate that it's not a hardware problem, but an XP driver problem. Yet any driver version I've tried failed to fix the problem. Any ideas? Please let us know if you found someone's advice to be helpful.
