I have a dell dimension e521 that always freezes randomly when I watch a video. The audio stutters, the keyboard turns off and the mouse doesn't work. I also notice the computer freezing sometimes when I wake up the computer after it goes to sleep. I shake the mouse and click and I hear a beep sound right before the computer completely freezes.
Does the PC work fine on everything else other than videos?

The PC works fine only videos would cause it to freeze, especially full screen videos. All videos make the CPU usage spike and the fan gets pretty loud as well.
I've been having this issue for about two years. I notice problems when my computer started to really slow down. The CPU usage was very high so I cleared out unnecessary programs, added more RAM to my computer, and brushed off excess dust on the fan. Afterwards my computer was running fine but then it started freezing when I played videos. I updated all my drivers that are available.
My graphics card is a NVIDIA Geforce 6150 LE.
