I'm having a very annoying problem, I have a computer that started getting an IRQL_NOT_LESS_OR_EQUAL stop error, after some extensive troubleshooting I decided to reformat, but I couldn't even get to the repair console with the original hard drive, so I tried a different one, which would act like it was going to format the drive, but never actually did anything and stayed at 0%. So I formatted a different hard drive in a computer identical to the one having the problems, then put the hard drive into the problem computer, but it would get a stop error again after a few minutes of booting up. Out of curiosity I tried to reformat the hard drive in the problem computer, but now I keep getting errors where setup can't copy certain files over. I've tried a different XP disk, and a different CD-ROM, and I've probably tried to reformat 4 different times, each time getting a different file that can't be copied, if anyone has some advice I would appreciate, and sorry this is so lengthy, but I wanted people to see the whole process up to this point.
