This type of behaviour can be caused by your computer overheating. You can check your system temperatures with SpeedFan, which should give you an indication of whether your system is running too hot.

Also, I would recommend that you open your computer case and make sure all the fans are spinning okay and that there isn't an excessive amount of dust in there that would impede air flow. See the following Bleeping Computer tutorial for guidance on cleaning inside your computer.

Thanks. Yeah The big noise happened around 20 minutes ago, Causing it freeze.. and me having to manually restart it. Again. Im really leaning towards throwing this computer out the window, It's getting pretty ridiculous. And the wierd part is that it only happens when watching videos, And As I've Discussed before, MY cpu is always at 100% while watching youtube videos. My RAM Is redicuously low, Ill get a new computer

It may be your graphics processor that is overheating, which would explain why it only happens when you are watching videos.

What process is using all the CPU when it is at 100%?

In conjunction with Budapest post. I would download Process Explorer. Process Explorer has a CPU History graph and it can show us what process is doing that and some other things. It just like a Graphic Interface for the Task Manager.

Process Explorer is located here http://technet.microsoft.com/en-us/sysinte...s/bb896653.aspx

Is this a lap top or a desk top? I think thats the most important question here.
