Doesn't look really bad but the 3.3v is awfully high:
+3.3v: 4:08v
Im not sure if that would have a freezing affect on the pc but i dont think it is good either. Do you by any change have an other powersupply , or one you could borrow , to test with?
And can you also post an Hijackthis log to see what is running on youre pc? See link below in my sig to download
