I have a HP xt933. I bought a new case to put all of the HPxt933 components into. The old hp case is way too small and impossible to upgrade. I switched everything over into the new case, and got everything setup and plugged in. Once i booted it for the first time, it came on for 5 seconds and shut itself off with the error message cpu fan not on. So at this point i kept trying different settings to try to get the fan to work but nothing. Now when i hit the power button, nothing happens and the bios wont even turn on. Absolutly nothing. Its almost as if i dont have the pc plugged in. The powersource light comes on when i plug it in but when i hit the power button on the front of the case the light switches back off. Im sure the power source is good becuase i tried another power source and the same happens. Im positive the CPU isnt fried cause i took off the heatsink and looked. Please help im out of ideas.
