|Re my # 3:|
Are you running XP sp3 on that? Can you run a virus/malware scan and see if anything turns up?
The most recent aspi version (I think) is 4.71.2 but that dates to 2002. Because it's provided by Adaptec sometimes there may be installation problems if it doesn't like your hardware. Therefore you can use ForceASPI 1.8 to install it. That is available here:
You may also want to go the Microsoft XP update site and let it run its scan and see what it thinks you need.
Ubuntu Cheeta, Ubuntu !
