I have already posted once with no replies. I will try to provide more info. I am working on this computer for a friend. When I tried it the first few times it would freeze on black screen with cursor. I kept trying to start and finally booted to windows. I was able to update the anti virus software and run a scan. It found some infections and removed them. I also got all latest updates for XP. There was also the dreaded fake virus software installed PAV.EXE that I could not remove. I downloaded the MS malware removal tool and ran. After doing all the above I was asked to restart for changes to take effect. The BSOD started and computer will no longer start at all. Windows will try to start you can see the windows splash screen and then desktop with no icons. BSOD will then appear and reads the following: Stop message driver irql not less or equal stop 0x000000D1 followed by the 4 parameters than are different everytime you restart. I cant boot into safe mode either. What can I do?
