Computer freeze-ups

[dj_bowser]

Since about 2 months ago, my computer has started freezing often.
It usually happens when trying to run a movie file or use my webcam or anything of the sort.
My computer just completely seizes up and i am forced to restart. Could my ram have gone crappy or something?
Any help is appreciated , thank you

I would suggest you check your HD for fragmented files and if needed run a defragmenter as high levels of fragmentation may be a reason for your mentioned problems.
