Hello all. Let me start with a list of parts to get that out of the way.*
Asus Maximus XI Extreme Silicon Lottery Delidded 9900K running at 5.0Ghz all core* *Asus Thor 1200W PSU EVGA 2080ti Kingpin Edition EVGA sound card 32 GB Corsair Ram (not sure of speed but was on Asus QVL) Full Custom Waterloop*
With that out of the way, let me start. Built this system about 18 months ago and it has been a rock solid gaming powerhouse. Never had any problems until this morning. Before going to bed last night I shut down the computer and everything was normal. This morning I go to turn it on and all I get is about a half second of power with a click. Mobo and all components still have power as all the normal standby lights are on as normal. Mess around with it a bit and having done this a few times before I figured the PSU died. After work this evening I pick up a Corsair PSU just knowing that will fix the problem and get me running while I RMA the other one. As you my have guessed, this did not fix the issues. Exact same problem as before. So I dig in to all the troubleshooting I can think of like unplugging everything and disconnecting all the internal part to try for a barebones boot but all to no avail. The only clue I have, which I spotted when going frame by frame on a video I took of the issue, is that in that very short period of time the PC tries to boot, it shows a Q Code of CPU00 in the OLED screen. I am out of ideas and figured I would post here to see if anyone else has any ideas. Going to try to contact Asus tomorrow. Thanks all!
