[Perf]

for some reason which is beyond my computing knowledge my pc has started to run very slow.
when i open anything for example outlook express it appears that nothing is happening but give it some time and it eventually opens. the same with any other application such as daoc or vent or anything for that matter.
the pc is not new by any means but this a recent problem. i have zone alarm and avg running but i dont think these are causing it.
i ran a registry cleaner program which cleared loads of stuff.

any suggestions would be welcome

for the record. p4 2gb, 1.25 mb ram nvidia geoforce 6200 256mb

thanks
