One day my computer started to act very slowly and watching videos etc. didn't run smoothly. Playing games like CS was impossible, even facebook games lagged badly. Cpu is like 80-100% in idle mode. Taskmanager shows that theres explorer.exe process which uses at least 40% cpu in idle mode. Also Ram usage is high in idle mode. When I start any program cpu jumps immediately to 100 and starts up slowly. Opening firefox takes like 1 minute in first time after reboot. I've run all scans that one of your members told me do to find a malware but said that this is definetely not a malware problem. Help needed to get computer running normal again!
