Hi there I have a HP compaq Elite 8300 It worked just fine until I rebooted it and went into the BIOS after that I just crashed and I didn't even change a thing yet, now all it does is just when you press the power button It just turns on for a split second then off again, I tried reseating the ram and swapping them out, disconnecting everything, changed the BIOS battery, pressed the clear BIOS button, swapped out the CPU with a known working one, changed your **bleep** proprietary power supply with a known working one, took the BIOS battery out for and hour to reset that way with the AC out and nothing connected but no nothing, and this is the second HP 8300 elite compaq thats did this to me, how can I fix this issue please help thanks
