I have an HP Compaq Presario CQ60 Notebook PC that runs on Windows Vista Home Basic. My graphic card is NVIDIA GeForce 8200M G and it is up to date. I recently downloaded a new online MMO named Allods. This game can run on my computer on the lowest graphic settings, but it does cause my computer got get very hot. This is a single computer thing, my boyfriend's computer heats up as well while playing this game. My problem is that on some occasions, my computer will black screen itself. I can still hear the sounds playing, but I cannot click or use my keyboard at all, resulting in restarting my computer. I updated my drivers, hoping it would stop the problem. It stopped for a while, but it's started up again. This doesn't happen to my boyfriend's computer (he's able to play the game with the best graphics because he has a good graphics card), so I'm sure it's something with my computer. I'm not very computer literate, but any help on solving this problem is greatly appreciated.
