What's causing my computer to reboot and lockup during gaming?

Especially in Battlefield 2142 and World of Warcraft, my computer reboots itself or locks up after about 10 minutes of game play. I've downloaded the latest Nvidia drivers, and changed out the power supply but it's still doing it. It only does it during gaming, it's fine otherwise. Any advice I can get on how to fix this would be greatly appreciated.

2 gigs of ddr ram and these people are telling you it's that you dont have enough memory....oO I assure you you have plenty of memory. I would agree that you might want to have your fan's and heatsink's checked. Other than that it's a perplexing issue. Mabey have it looked at by a repair shop. Good luck!!What%26039;s causing my computer to reboot and lockup during gaming?
What is wrong is you have dust on your inner computer. When you're playing a game that makes your computer work a lot and causes the computer to get hot, the fan kicks in and cools down the computer. When there is dust on the computer, it insulates this dust and makes it so hot the fan can't even cool it down, so the computer shuts down so it won't catch on fire.



Just clean the dust out and it should be fine.

it could be over heating



make sure that the fan on the CPU is attached correctly... and you should also purchase some more fans to put in the inside back and front of the case to keep the airflow moving

Teyana, the previous answers could all be correct with the dirty cabinet or low memory, but I suspect there's a problem with the video driver. Check to make sure you have the latest driver installed.



Good Luck
