I am working on Dell 'puter, 2.8ghz, 512mb, 40- gig, xp pro. It had some freeze ups and got slower and slower, like an hour to boot up; no errors just slow, when trying run an application it will generally freeze up. Dell support declared it was software related. Tried to upgrade the HD using seagate disc utility but it froze up trying to install it so just replaced the drive and set up XP on the new drive. It took 10 hours to get it installed, every step was too slow, format, copy files, etc. So obviously it is not the drive causing the problem. Could it be the cpu, ram, mobo,? any ideas out there??
