The only time my PC freezes would have to be when i open up facebook on google chrone on a new tab, it would only happen when i start up my PC, the freeze would usally last for few seconds then resume back to normal. I tried opening facebook on Internet explorer, and Google chrome to find if it is facebook freezing my PC and by freezing i mean, it just completely stops i can't move the cursor or open up start just by pressing the start key. I had a look at Performance on norton and the top one that spiked up was something called " ccSvcHst.exe" which was norton thing but it was only at 19% (i think). I tried going into safe mode and nothing happen. I tried doing some command prompt thing but that did nothing. This has happen everyday when i use my laptop the only time i get it is pretty much when i open up facebook on a new tab that's the only time when it happens. If the problem would maybe be google chrome then i would of wen't to Internet Explorer but IE is so slow (my opinion).
