So this morning everything was fine, my CPU usage was at its normal 20% or so, occasionally up to 40 if I was playing games or something.
After coming home this evening however, turning it on again was taking much longer than usual. It took about 15-20 minutes to get to the desktop, and another 5 to load the icons properly (probably because I have Skype set to run automatically on startup).
When it finally worked with enough speed for me to actually do anything I checked my task managers performance screen, and it was up around the 90% area, and then hit 100% and I experienced the same immense slowness with everything.
I do get periods where my laptop is usable, but even then my CPU usage varies wildly between 30% and 80%, with the only stability coming aroudn 50-60% mark.
I am currently running an anti virus scan (I use ESET NOD32 Antivirus 5) which is almost complete, but I doubt that it will help - has anyone got any clue how to fix this?
My laptop is a HP Probook, model number P4510sVP7570Q5X320NIBNCN32Wa. I run Windows 7 Home Premium 32bit on an Intel Core 2 Duo processor, roughly 2.26 GHz.
