can overclock the graphics card damage the rest of my system???

[Geekazoid]

ok here is my story i sold my 295GTX because i wanted to move on the DX10 nvidia cards (which are taking there time!!!) and i bought a 38 pounds Asus Magic 9600gso :*( to make do.... now i was tempted to overclock this cheap as chips crappy graphic card i managed to get...

625 GPU *550 (stock)
1562 Shader *1375 (stock)
and 550 Memory *505 (stock)

i used EVGA precision to overclock and tested using ATI tools and Furmark after every 10mhz jump for crashes and artifacts... now here is the odd thing i tested to the above clocks in ATI tools and Furmark and no crashes or artifacts and a peak GPU temp of 71oc....

now when i game e.g. wow or any other my Nvidia display driver stops responding and crashes and recovers why is it doing this in game??? anyone explain....

Also can overclocking only my graphics card damage the rest of my system cpu, ram, mobo etc and they are already overclocked (see my specs just change the 295 for 9600GSO lol)....

going from a 295 to a 9600gso im having withdrawal symptoms :*( lol...

thankyou all

if i turn down the clock back to stock everything works fine its just the overclocked settings but i did research on this 9600gso and it sould clock a little higher well the memory should but mine is unstable as it is...
