Thing with the power supply was more of a suggestion, I don't believe its causing your issue
Most of us view the power supply as the heart if you will, power supply to low or broken it can mess with everything but again I don't think this was your immediate issue was just throw in some info your way
But as I said above you can find a bunch of 00 code threads
Typically they are from 1 of 3 things
1. Bent pins on the CPU, which if you haven't changed anything shouldn't be the issue (but anything could happen lol)
2. A small piece of metal is lodged somewhere arching a connection, which again since you haven't changed anything and reboots fix it I don't think this would be the issue either
3. A faulty board, which I can't see the board just ****ting out but again anything can happen
On the board itself there are small led lights, not the main Q code, there small single lights for things like CPU, memory, hdd ensure none of these lights are on
As for the Q code, its supposed to run thru a bunch of codes on normal boot, it will end on A0
Most likely if you were to call tech support they would probly have you remove the board from your case and try assembling it on the box it came in with the bare minimum attached, by bare minimum I mean like if you have more then one ram card only installing one, if your CPU has built in graphics then leave the GPU out,
Basically there doing this to troubleshoot the 3 things above, by removing it from your case it would possibly remove any metal slivers arching connections, while you were rebuilding it on the cardboard box thed probly have you check the CPU pins out usually with a magnify glass
