|mmm which anti-virus util have you used? Might be worth running two freebie scans (on-line).|
Sophos has one you can download/run - a freebie; and also Trend have their Housecall...
Suggest you google using:
Sophos free antivirus windows XP.
as the search term/string; and follow Sophos instructions re' their freebie...
And for Housecall, go to:
Housecall is an on-line scan and takes a wee while. I have it found useful to run on occasion; if only as re-assurance...
I run Sophos freebie util on my Mac systems...
If you can boot into safe-mode and with networking - so as to get on-line... do so; and scan that way.
Also ensure the drive/partition/s is/are fully defragged too.
And ensure you do have a Swap-file (Page-file) enabled...; possibly it's been disabled somehow?
Also... even though it may take a while from what you say, suggest you copy all your files (personal stuff...) off the system as is. Typically optical media (and if possible another HD). Useful to have important "stuff" duplicated on two types of media... Verify copies are accessible on system that made them; and ideally one other.
This is to safeguard all those files in-case the system decides to throw a wobbly.
I have known (in days of yore...) of an HD that simply slowed down and became effectively useless... The system more or less ground to a halt. My local PC manufacturer who also sold drives - and the one in question was from him - replaced it for very few pennies... ; copied the olde drive to new - system then was fine again!
In Task Manager do you see any processes running you don't recognise - as in programmes etc. that didn't orta be there?
How does the system perform in safe-mode; and have you added anything new to system - software or hardware)?
Can you go back to an earlier Restore Point; and see how it fairs?
