I just reinstalled updated my drivers etc and installed rainbow six lockdown the new game and even on low settings i hear the computer beeping at me and eventually it turns itself off after several beeps.when it reboots i get no error message and the ati software said the temp is 83c and its not overclocked.I have had problems with the ati drivers since i got this card(msi version) the disk it shipped with had drivers that gave me problems and the new drivers havent helped either oh and i did a long format when i reinstalled.what do i do next to fix this problem?
