CPU usage at 100% unless task manager is open

  1. So I booted up my computer today and the cpu usage was at 100% and the fans were raging. I restarted with no fix. I did a scan with my virus scanner with no viruses detected. I even scanned in safe mode with no prevail. Note: The cpu usage wasn't at 100% in safe mode, just normal usage around 1-5%

    When I open up task manager it goes back to normal. So basically I'm stuck using my computer right now with task manager needing to be open just like a lifeline. Any help please? I'm really frustrated. The computer is a Sony All-in1 L series that's 3 months old!

    If you have a warranty on it. You should contact them. Let them fix it for you. At 3 months old you should not be having any problems. If it is something simple calling there tech support might help you out. You are still under warranty so it should be free.

    Sfc /scannow to make sure no OS corruption occured

    This is very interesting. Try opening Resource Monitor (Task Manager, Performance Tab, click button) and closing Task Manager. See what happens.
