I bought my xp version from tigerdirect. Anyways, I couldn't delete any partition. When I went through the steps to reformat, it would just install another xp pro on my pc, so I have like 5 xp pros one my c drive.
Someone on another forum told me to take out the drive, hook it up as a slave on another pc, and format it. So I did, then put it back in my pc, and installed a fresh xp pro. Now it works fine. The only problem I have now is that my 8800gts is having really bad graphics problems. My games look horrible.
