The computer boots fine with the stock PSU, and if i switch to a OCZ PSU the cpu fan spins abnormally fast and the computer will not boot.

if the computer boots the power button will light up

but with the OCZ PSU the power button wont lit and black screen with the CPU fan spinning at high speed

Any ideas?

ya there is nothing on screen, removed all ram but there was no beep. i believe all the hardware is fine because it boots up fine when i switched back to the stock PSU
