Screech Of Death

My computer is an Acer Aspire 5732Z,I have updated all of my drivers and I have cleaned my Registry multiple times.
The Problem I am having that I am still having after doing all of that is whenever I play audio/video/games/etc my computer will randomly get the "Screech Of Death" for 2-5 seconds,sometimes it will just screech,sometimes it will freeze and screech,and sometimes a timer will appear and my program I am running will just stop working,like windows media player will do all that and sometimes stop working and I have to force end the process.
So I am at a loss here,I would appreciate it very much if you could help me.

Thank you.

P.S. I usually get the screech of death every single time I play a song or video,and my computer will not freeze forever it will fix itself and continue playing after that 2-5 seconds or if it doesn't I will just have to end the process.

I made a video to help you understand,ignore the green line,must be some tinypic glitch. Video - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting

Un install your sound card drivers and reinstall.

Thanks,but I already tried that =/

I guess my computer had custom drivers,I'm not suppose to update,and that is what was causing it,thank you guys.
