Random crashing

[elork]

I have had my PC for little over a year now, Ever since i built it, it randomly freezes, the entire computer locks up instantly and horrible sound comes roaring out of the speaking and continues untill i turn off the PC manually. I brought it up to geek squad about 6 months back and they kept it for a good month and no one up there could figure out what was going on with it.

I just recently reformated and checked my sytem errors and already in less than 8 hours have 16 warnings/criticals...figured i toss them up on here hoping they could possibly shed some light on whats going on.
