only takes m's here to open any version.
You should still test with PS2 mouse and keyboard, hardware that worked once does not mean it now works.
Not saying usb mouse/keyboard is def the problem but you have to rule it out.
Not sure if a log file will help unless maybe you enable show all devices and debug mode under I/O
post the filter driver load order
remove any disc's you have in any reader/writer and leave drawer open , does that make any difference ?
I would also consider removing the ide controller and letting windows pick it up again.
Replace all IDE cables
try checking your memory with memtest as well.
make sure your antivirus definitions are current and scan whole system not just C: same for spyware, if your not already using spybot search and destroy download it and update it and scan whole system not just C:
also download a rootkit scanner and scan
check your hard drives for errors and also defrag them
