I have a lian-li case it has a detachable led connector. You dont have to disconnect it from the motherboard

Have you tryed putting your original processor back in? What you do mean by doesn't power up. Do you get any lights/ fans coming on?

Is your power on switch working? You can temporatly short across the two connector pins on the motherboard to try and turn the system on. Also check that you havent bumped any jumpers and try reseating the memory. If that doesn't help take out everything except for memory, cpu, and power supply and fans then see if the system will start (fans spin) that way.

You can use a screwdriver or a jumper across the two pins that you normally hook the power on button to. (is the conector on the right pins now)? This should be a momentary contact just like the power on button. The last thing you can try it to take the motherboard out of the case and try booting it up there. This will eliminate any booting problems caused by the motherboard shorting to the case or standoffs. Failing that you will need to test your cpu and memory in a different system and finally replace the motherboard. BOL

Was your pc was working before w/ the a7v333 mobo until you replaced the cpu?

Do you see where the ATX power switch plug is on the mobo?
The 2 pins should be the 4th & 5th pins on the lower row of jumper pins to the right. The black wire should be to the left pin and the red to the right pin. If that doesn't work, remove the plug and short those 2 pins w/ a screwdriver, that should start your pc.
