ok, i have no idea where this problem came from or what is causing it cause it leaves no error message when it occurs or when i have to restart my pc from it. Well anyways, whenever i try to watch any video that i downloaded, streamed off a site, etc... the whole pc just locks up totally. I thought at first it might have been something wrong with some of the codecs i had installed but i uninstalled all them and tryed it and it did that same things. i dont know how it happened, one day my videos worked all find and dandy and then the next time i try, it locks up. I planned on doing a system restore but i had my system restore turned off so none of my last restore points were saved.
