Not its not the only drive in the system, but other drives were not even accessed for any files. I was under the impression that viruses could not activly launch themselves from a non boot drive unless you tried to access/run the file that was infected? I seem to have it stable so far (still need to install more drivers and software). If the problem persists, I could temporarilly disconect power to the other drives while installing. Would that matter? Fyi these other drives were currently running in a system that had no notable virus or trojan activity (nothing reported by trend micro 2008 or spybot anyway, and I wasn't having any problems). I'm reinstalling because the boot drive failed (actually it gave a smart hardeare falure warning and was crashing a lot).
Yes I am on a local network (just the computers in my home). I had not ran the network wizard to conect to other computers yet though I was using the shared internet conection to access the web for updates. There is no notable virus or trojan activity (that I am aware of) on the other computers (they all run av and firewalls).
I did have the windows firewall on, though I'll probably replace it with another firewall once I get things working.
I already have a router in place. Its this one.
I did think of one thing (kind of a long shot but who knows). I usally have the wireless disabled on the router as all my conections are wired. I installed that router a month or two ago, and I thing I left the wireless enabled. Maybe someone hacked my wireless? If they did, I didn't have any noticable problems on any computers including this one till the reinstall though.
