[SOLVED] Q-Code 00 on ROG Maximus X Hero Wifi AC

[Rafael Milagres]

I bought an used ROG Maximus X Hero Wifi AC, along with brand new i7 9700KF and a set of 2x8 Gb G.Skill Trident Z ram, but when I try to turn it on, I get a static 00 Q-Code and no video signal on my graphics card. I have tried removing everything, except the CPU, cooler and GPU, tried using only one ram, changing the CPU watercooler to a regular air cooler, and also tried updating the BIOS to the latest one for my motherboard a couple times (also double checked for mobo bios version). Every time I get the same 00 Q-Code. The previous owner of the mobo said it was working perfectly fine, and the GPU and PSU are from my old build and were working perfectly fine as well. I have tried looking online but nobody seems to know a way to fix this

Qcode 00 is difficult to pinpoint as it's not documented, however it is more than likely, either a MB, PSU or CPU issue and each in turn will have to be tested.
Try bringing your CMOS back to default If you are OCed and update the Bios and chipset to latest version (2402) (instal using your rear IO panel) considering you have new RAM.

If this continues then you will have to benchtest outside your case to determine the culprit.
Just check all cable connections prior to dissembling your system, in case something has come loose.

Only way to check (if the above proves fruitless) is to try swapping PSU first, then inspect your CPU heat sink or bent pins.
If both PSU and CPU are proved to be good then it may be the Motherboard,
