First of all I would like to say hi to everyone, since I am new here. Intel core 2 QUAD Q9550 2.83ghz 4gb Ram 150 gb drive 70 gb hard drive nvidia 8800 gts I came up with the following problem... I recently installed Medal of honor Airborne on my computer the first few days I was playing fine. Then suddenly yesterday I got a Blue screen and my computer restarted automatically and when it was about to boot to windows I got the following error message: reboot abd select proper boot device or insert boot media in selected boot device and press a key I had to clear the CMOS RTC RAM data and the computer booted up perfectly. I don´t know what can be causing this problem. I don´t know if it the power supply, the game, the video drivers? If somebody could please help me I will be very gratefull. I can fix the problem but I can´t avoid it. When the game installed, it automatically installed Physx which is a sort of driver for nvidia, that comes with some new games. I don´t know if this had anything to do with it. Thanks a lot.
