I just noticed recently that my computer has been running very slowly. when I go to the control pannel and open up system then go to the performance tab I see that my system resources are very low at around 34%. I pushed ctrl alt delte and closed all the programs running in the background except explorer and it still says I have only 34% system resources. I have scannned for spyware and viruses and have found nothing. Whenever I try to open up only 1 program, my system resources drop all the way down to 3-5%. What is causing this?
