Frequent crashes, reboots only in vALVE games?

[Maddy.G]

I have been playing Counter Strike from quite some time but when I upgraded my CPU from an Athlon XP 2100+ to a 3000+.This also included the newest BIOS which are upgrade also a change in Front Side Bus from 266 to 333 and a different CPU multiplier. After all this up gradation when I try to play CS it starts crashing the desktop closing in a few seconds from starting a game. It just comes out of CS window to main window.

This problem may be because that you have not install your games properly that is you have not install counter strike properly which may be behind such behavior while you are playing this game in your machine. Try to uninstall it for some time and just reinstall it after some time step by step and following directions mentioned. This may solve your problem with game crashing in between.

The game version you are using may not be supportive in your machine specification. As you mentioned You have upgraded your system cpu from Athlon XP 2100+ to a 3000+ with latest version of BIOS in it. Game may not be compatible with your system specification. So try to fix if this is the problem with game to crash.
