Answer 1

To be honest, it really sounds like your harddrive is failing, and with those disk sizes, it is possible they are old drives (3+ years).  I believe this may be causing your BSOD's.

If you're adament you've got a virus, then in safemode run "Hijack This", it might find something the others don't.

Answer 2

I think  hardware problem
