Working on my parent's computer, but I think I may be in over my head with this one. They started with the internet security 2010 virus. I got that off using a combination of Malwarebytes and Avast. Computer was good for a while, then started BSODing on them. The log showed instances of NTFS.SYS and other ntfs-something or others-.sys being the driver that crashed. As I understand, these are pretty core things. Some internet searches gave me the most likely reasons as bad memory, or curroption in windows. I loaded up a memory tester and ran it for a few passes, but no errors, so I pop out the XP cd to do a repair installation. It fires up, deletes a bunch of things and goes into the install, however hangs where it's 34 minutes remaining. Installing devices is the 'stage' I believe. On hard reboot after the hang, it goes into the install again, prompts for the XP cd and again hangs at the same point. I'd appreciation any suggestions on where to go from here. Thanks in advance.
