Window XP lagging badly

[multiple sarcasm]

I have XP pro, service pack 2 which has been running fine for months.
Recently noticed an error on startup relating to a dll for my device driver,
so I re-installed software.
Since then have had problems. One of the dual core processors is constantly
running at around 40-60%. Further investigation reveals that DPC's (Deferred
procedure calls) are using up this processor time. This is causing serious
lag to the system and hard drive activity is greatly increased. I am truely
puzzled. I have even tried re-installing the OS, which seemed to work for a
couple of hours, then back to the lag. I am wondering if I am may be having a
hardware failure which is causing the problem, although system seems to be
working fine in safe mode.
Can anyone shed any light on this problem? Or if not, can anyone tell me how
I can find out which devices are usings the DPC's?
Thanks

Why don't you upgrade to SP3 and see if this will not solve some or all of
your problems.

It is generally recommended that you do not update an existing system
with a problem as it can make solving the problem more difficult.

You don't happen to have 2 network adapters installed do you?
