I’m having graphics problems during playing games – I started Black Ops the other day and it worked just fine and now i run it and it worked for like… EIGHT SECONDS, it just froze and made a drrrrdrdr sound and the monitor was all in red-greenish squares of some kind. I’ve reinstalled the game and it didnt work and this also happens with other games. I’ve tried System Restore, didnt work.
Make sure you’re using the very latest version of the graphics cards drivers, but it does sound like a hardware problem due to the sound its making.
