Okay, I play RuneScape or other online games and I even watch YouTube videos and my computer shuts off randomly without me doing anything and when shut off it makes this odd sound like a high pitched beep and a low pitched beep going on and off... then I need to shut down the whole power supply for it to stop... help me please!?

usual sign of overheating. open the case and blow out the dust. confirm the fans are all working

Take off the side panel of your computer case if possible. Use your computer continuously doing the same things as you mentioned above. If the problem doesn't reproduce, your computer is overheating as stated by wanderer. Jarvis -Technician TekTime www.time4tech.com

operating without the side panel on is NOT recommended unless you also place a fan blowing on the unit. Airflow is designed with the case closed. Opening the case leaves static air pockets and the air doesn't flow as designed. This can produce false readings and overheating.

download SIW to see what your temps are Some HELP in posting on Computing.net plus free progs and instructions Cheers

This can produce false readings and overheating. ______________________________________________ Well..that depends on what type of air flow is in the case. For instance, if you have only a CPU fan and one power supply fan that is located on the bottom of the power supply; still within the case - there is no wrong done in doing that because the warm air has an escape. I recommended that temporarily to see if the problem persists. I have never had a problem with a computer overheating when trying that method. It helps to rule out other factors.
