Hi all Im new on here, Hoping to get some help :) My Cpu speed keeps getting stuck at 100% and my whole comp just slows down e.g. cursor lags alot nothing opens etc. When i check task manager to see whats causing this, it shows "explorer" to be the open using up the cpu speed. Ive tried ending the process and then running explorer.exe again and it works fine for a few minutes then does it again :S. Ive have done an antivirus check, Used spybot search and destroy and also tried the Kaspersky rescue disk check and they all showed the system to be clean :S My system is an Acer aspire 8920g laptop running vista 32bit. Please could someone help Thanks in advance MrSingh
