High CPU Usage At Random Times Unless A Task Manager Is Open

My problem is basically what the title says, I have dual core processor where one core gets loaded to almost max and the other one at 20%. I can tell this by a CPU monitoring gadget and I have no clue what to do. If you google the problem you come up with delete igfxupdate.exe, but i haven't seen that file and there's no way to find my file, that I know of cause it stops whenever A task manager is open. whether it be windows process explorer or some other. I've run all the maleware programs under the sun and i'm at a dead end right now. Any help would be appreciated.

Run for a while in clean boot. If the problem does not happen, slowly put the services back making sure that the problem does not occur. When the problem is service is back the problem will happen.

Ok so I found that svchost.exe werfault.exe and wmiprevse.exe all close whenever i open task manager. People have said that wmiprvse.exe could be the problem but it has come up negative. So if anyone has an idea about whats causing it know that'd be great.
