I AM NOT RESPONSIBLE FOR ANY OF YOUR ACTIONS! YOU BRAKE IT, TOO BAD!
hi...

try to use Rivatuner (google it!) its an amazing overclocking program and its relatively easy to use. Make sure you have a GOOD cooling system, and please download
http://www.speccy.com to watch your temperature...
When you start overclocking, just increase by 0.01 - 0.02 Ghz at a time... Start overclocking a TINY bit, then reboot to see if it even wants to deal with you (i've tryed that before...) you should see clear signs when its time to stop... (screen flicker & BSOD :S) please have speccy open when you start overclocking..
i hope you find this helpfull... goodnight..
