I just bought a new VGA it's a geforce 9500GT, but the memory clock is 400Mhz instead of 800Mhz. When i try to overclock it back to normal it starts to malfunction when i get it up to 450Mhz. Please help how to fix this problem. Thanks!

When idle, your vga is downclocking to enter safe-mode... Did you try to play some games? See whether the clock is rising or not...
If the problem still exist then it's a good time to RMA your card.
