i got a blue screen on my computer saying a problem has ben detectedand windows has been shut down to prevent?

none of em has faced this problem more the times i have faced.

The basic reason is that your system couldnt stand the load of the program you might be running at the time of this problem(U DIDN't MENTIONED WHAT WERE U DOING AT THAT TIME).

I always got this blue screen when i tried to play a bulky game on my PC with 128 ram.The system starts dumping the physical memory.

So if u want to solve your problem go for HARDWARE UPGRADE.

If you have Windows Vista this is a security feature that gets reported to Microsoft and if there is a solution they will provide an update for you. You should update Video and audio drivers too so you have the latest to run today's programs.

Could be a problem with device drivers, hardware or software. This problem can be solved by uninstalling new software, updating device drivers and making minor configuration changes .
