AMD Athlon XP 2.7+
1 GB SDRAM
GeXcube ATI Radeon 9800 XT
Philips Brilliance 150P4 LCD monitor
On a whim today, I decided to visit Windows Update and install a few driver upgrades. From memory, I installed the AMD, Realtek and Philips monitor upgrades. There was an ATI driver one there but I'm always a bit wary of video driver changes, so I didn't install that just yet.
Of course I was asked to reboot, and of course I said yes. Boot-up proceeded as usual, with the Windows XP logo and progress bar displayed. Then, at the point where the login screen is normally displayed, I got a blank screen, then... "No video data" which is what the Philips monitor usually displays at boot/reset time before the video card wakes up.
Then the monitor goes into sleep mode.
I rebooted into safe mode, I can get a display fine. However, every time I try to boot into normal mode I get to the point where the login screen should be displayed, then blank.
I know that Windows is booting properly. I happened to have the password setting off for my main account, so it loads up without user input. I have a few apps on startup that play sounds, and I can hear 'em start... just can't see 'em!
I blame the monitor driver update. The Radeon card is new, but it's been working just fine for the past 48 hours and this problem occurred IMMEDIATELY after I visited the Windows Update site.
So, can I force a driver downgrade for the monitor somehow? I looked at Display/Settings/Advanced/Monitor while in safe mode, but the 'Properties' button is greyed out so not much use there. System/Device Manager yields no useful info, as the monitor does not appear on the device list.
I have an appropriate driver (I think) from the Philips web site, just need to know what to do to convince Windows that I need to 'reinstall' the monitor.
