Another one of my friends called to come an look to see what was wrong with his computer. It is a home built computer built in July of 07. Here is the problem. I went and checked it out and this is what happened. I turned it on and just played around for a while and it worked fine. It ran smoothly, had good speed and looked just fine. I started doing some more things and opened up a couple browsers. I then went and turned on media player when the browsers were on and started listening to music. The screen got a little fuzzy and all the words and pictures etc went multi colored and the machine froze. The one thing I noticed though was that the speakers had some tat tat tat tat sounds continuously coming out of the speakers. I forced shut down and and restarted and tried the same things to have the same result. I know it is not media player that caused this to happen because media player was not opened when it happened to him. He just had several tabs and apps open at the time. Video card going bad? PSU? CPU? Memory? These are the components of the machine.
