It happened suddenly, but I did reformat. I don't recall when I installed the chipset drivers prior to the format, whether or not the ATI driver was already installed... I will try installing them first, then the ati driver, and reverting as you say
I haven't installed the chipset drivers... On that page you linked, it says to revert to the Microsoft driver "PCI standard PCI-to-PCI bridge"... since I haven't installed my chipset drivers, I already am using the "PCI standard PCI-to-PCI bridge" driver...
I also tried installing my chipset...
I have been experiencing this problem for a few weeks now and have just been running without any display drivers installed. I finally buckled down and reinstalled Windows XP last night and after installing the video drivers the BSOD returned. I haven't installed the hyperion chipset drivers, so...
