Individual User Load Time VERY Slow

[John]

Computer

Less than 6 months old
XP Home
XP Office Pro
2.8 P4 GHz
512K ram
Optimum online cable modem
McAfee Virus Scan 8.XX with fire wall, updated daily
drive scan bi-weekly

MS XP Updates always current

No viruses detected with McAfee

Current Spybot and Bazooka detected no spy ware

In the last week personal preference load has gone from
less than 30 second to approximately 2 to 5 minutes.
Once loaded switching users is quick, and once loaded the
system performs flawlessly.

Any suggestions on what to look for as a possible cause
to the current slowdown in load time or how to improve
the load time?

Thanks for the help
