Computer guys, need your advice - one of my computers that just runs charting (currently OEC charts) recently started slowing down to the point that I really noticed. After checking it out today, it looks like something is causing the CPU Usage to spike massively - pushing 100% OFTEN. If I am doing nothing with no programs open, it runs at 0-2%. As soon as I do anything - open a browser windows, etc. - it spikes all over the place and pushes 100% no problem. The tech guy at OEC said possibly a hardware or 'system' issue. Problem is that I have no idea what to check for and how. How do you try to test your system yourself to find the problem? Or I am just wasting time and should take it up to the local repair shop? Thanks!
