Hello, my mom has a desktop computer, with windows xp, service pack 3.. she is elderly and doesnt know a whole lot about computers so when I came over today I said I would take a look and see if I could find some help for her. Her computer has been freezing up on her very often since she said about a week ago , when starting up the computer we get a black screen it says Drive 2 not found, Parallel ATA , PATA - 0 (PRI IDE MASTER) Strike F1 Key to continue or F2 to run setup utility. When I hit F1 it does start up without any more errors but still running really slow. I did some of the steps in the virus section and got up to the supera anti spyware step, I did a complete scan on there and it found 188 threats, I quarentined and removed them and then rebooted when done, the black screen came up again when rebooting. So now I am here saying please help?
