My computer (Dell Inspiron 520m laptop, XP home, SP2 build 2600, 600 MHz, 512M RAM, all updates) has been running much more slowly than usual. I've run a virus check, ad-aware and spybot, and removed anything found (just a few items on ad-aware and spybot). If I pull up task manager to see what's going on, I have the usual list of processes. However I've found that more often than not, taskmgr.exe is showing 30-50% under CPU, nothing else is showing significant CPU demand.I've never seen this before - normally taskmgr takes a few % only.
Is this a symptom of something wrong that we can fix?
