It is running Windows XP Professional (SP3). The processor is 2.5 GHz; the RAM is 2.98 GB; the hard drive is 465 GB and about 90% free. The computer is used mainly for email, Skype, and some online games. Only a handful of programs get used much -- Opera, Firefox, Chrome, Adobe Reader, MS Word97, WordPerfect 5.1 for DOS. I use these same programs on two other PCs, configured identically, without problems. They worked fine here for about three years before the slowdown.
The slowness problem started suddenly a couple of months ago, not after installing any new programs or making any other changes to software or hardware. It has continued despite my trying everything on the BC checklist:
- antivirus scans (complete scans with MSSE and Avira in Safe Mode with Networking); found nothing at all.
- spyware scans; complete scans with Malwarebytes, Spybot, and Super Antispyware, in Safe Mode with Networking; only turned up the usual cookies, nothing major
- uninstalling any recently added programs -- not relevant; the slowdown did not occur after installing anything. I did do a System Restore, which I think (but can't remember exactly) brought the PC from extremely slow to the current slowness described above.
- Startup items: there weren't many, and I unchecked several unnecessary ones in Spybot's Startup tool; didn't help
- the hard drive is only 10% full
- checkdisk with error correcting done twice, the second time in Safe Mode -- found nothing
- disk was defragmented
I've also tried changing the desktop background to one of the standard images that Windows supplies, in case the photo we had took up too much space to load. No change in performance..
What else could be causing the problem? What else could I try?
