My sister's been overseas for the past year and hadn't updated her Mcafee Virus scan for long as she can remember (apparently not a computer nerd like me ) But now she can't boot into windows (the starting screen displays but it says can't find C drive) and then when I tried using the CD rom ( D drive) and it says invalid drive and now both A and B (dunno why theres a B drive?) drives go to the floppies and i can't access the CD rom. I was thinking if I reformat the computer's C: (I can access C drive but if I go to another drive, I can't go back to the C: cause it says C drive not found) Maybe the virus would go away and I can access the C: drive again. BTW its a old compaq presio notebook ( a pentium I, 233mhz...I know I know, she needs a new one but shes kinda broke right now ) and I can't access the BIOS. Any suggestions? I am going to make a windows boot up disk and a virus scan disk from my computer and hopefully, it'll be fixed. Any ideas?
