GTA San Andreas Crashes every 15-20 min!!!!

Many overclock for the fun of it and sees it as a challenge... That was why I did it before but now I can't get the same rush... :P
Good overclocking rarely makes any component stressed out so badly it would die before any upgrade anyway...

My guess would be on that your CPU can't handle the overclocking to a 100% or has been damaged due to bad cooling when overclocking and maybe GTA SA is a bit more sensitive when it comes to slightly damaged CPU's?
So set all clockspeeds to original speed and try again... If that won't help check the drivers again and as a last resort check your hardware (especially the RAM) for possible damages...
