Since I installed Win 2k I've noticed that every time I try to play a video file in either Real Player or Quicktime format, it gives me the IRQ blue screen of death either before, during, or after playing said video file. I don't have ACPI enabled and no IRQ's are being shared. Additionally, I can't change the IRQ #'s b/c the option to change IRQ's is ghosted. Would disabling IRQ steering allow me to change IRQ's? Does it matter what IRQ # devices use (ie. sound card and video card), or are all IRQ #'s equal? Hopefully someone has a solution.

Why are you tinking this is ACPI or IRQ caused ? The Video cards IRQ is most commonly configured in the BIOS. This sounds like the current Video Display Drivers is NOT 100% compatable with the Video Card. It's not a given that the automaticly detected Video Driver is the most efficient or most accurate. Obtain Windwos 2000 provided drivers from the manfacturer if possible. If Not, just as a control test, use a different Video Card ans see if the same issues results with the Play back. Good Luck

Ok im running Windows XP And like after 1 hour of whenever I do something that is heavy i get this error, IRQL_NOT_LESS_OR_EQUAL, Now I always got this error in Windows 2000 also. For some reason I cant find a fix? If anybody else has the same problem OR if they know how to fix it, please email me at letterand@hotmail.com it'll be greatly appreciated.

He thought it was ACPI because ACPI is garbage and usually causes problems like this. I've experienced it myself on 5 different machines with dramatically different hardware configs. http://www.geforcefaq.com/faq.cgi#hw:gef:troub:all1irqw2k -=Noc
