My new computer runs nearly perfectly on games like crysis (even in high graphics w/ 1680x1050 and no AA) then out of nowhere it just freezes. if I let it sit for a moment it goes to a black screen and says "Failure - Security options. Login process has failed to create the security options dialog." HELP! I just want to be able to play my computer games...
