My system does not boot and gets the Hardware 3.4 post code. 3 long red 4 short white. Manual says system board power crowbar or something like that. I am pretty sure I need a new power supply. Can anyone advise the right PSU and where to get it?

The crowbar is an electronic device. Unplug power cable from wall source. Wait 1 minute. Then plug back into wall outlet. Test the HP. This is supposed to reset the crowbar.
The Power Supply part # is L2X04AA, as shown here and explain here on page 1 and 7.
