    I made a mistake and changed the date of my computer in the BIOS. Then I was booting it up, not realizing my friend's Windows Vista disc was in the drive. I cancelled out and restarted. Now, 90% of the time, I get the DRIVER_IRQL_NOT_LESS_OR_EQUAL error when I start up. I looked in the event viewer, and sure enough, there is an error at the time that I altered the BIOS time (complete with the incorrect date). I am assuming that I screwed something up and that this is not an extremely coincidental hardware issue. My guess is something with a driver that was altered because of the Vista disc. I need to fix this soon. Can someone, anyone, please help out?

    Having the Vista disk in there didn't do anything. A hard forced shutdown could have whacked a piece of hardware, and that is what that error means. As for what it is, start removing plugs and pci devices until all is well.
