I have used XP on a FAT32 disk for several years, with no significant
problems. So, FAT32 is probably not the cause of the slowness.
Things to try/investigate:
1. From a command prompt, do CHKDSK C: /R. Then, reboot. Watch the screen
for 5-10 minutes for any sign of disk errors, especially any that CHKDSK can
not fix. Then, let the pC continue to check the disk bit-by-bit. This may
take hours.
2a. Defrag the disk using the MS (free) defragger. If things are not
improved, move on to 2b.
2b. Get Diskeeper, full version, and do a boot-time defrag, then a
windows-level defrag.
3a. Try starting in SAFE mode. Is that any faster? If so, you might havea
bad driver, or some other slow process that is not invokded when in safe
mode.
3b. If SAFE mode helps, try to discover what is the problem by doing a
selective startup, leavinf some things on and others off, but not less than
was on in SAFE mode. Use Run --> MSCONFIG to control the startup.
4. Have you scanned for viruses lately? Are your virus defintions and
software up to date?
5. Have you scanned for Spyware lately? Free spyware removers inclue
Spybot Search & Destroy, and Adaware.
6. How much RAM do you have? XP like > 128 Meg, but may run in as little as
64Meg, but not well. Verify the RAM sensed by XP by the main screen in
MyComputer --> right-click properties. If XP see less RAM than you have,
try re-seating the RAM or replacing it.
Good luck.
