Aurora r13 Wont Power On Until I Reset The CMOS.
12900KF,
3090RTX
32GB DD5
This morning I moved my PC to clean around it, now when i switch it on, the GEForce on the Graphics Card lights up, the fans start to spin but 5 seconds later the PC shuts down with no activity at all on the LED lights.
I have tried the following.
I reseated everything to no effect. I checked as best i could all the cables were in place.
I tried a power reset, ie removed the power cable, held the power button in for 30 seconds with no joy.\
I then reset the CMOS via the jumper which is really poorly accessible with the GPU installed and I got somewhere, because as soon as i returned the jumper to its normal slot the PC came on without me doing anything and took me via 3 ambler lights, 1 white on the front to the CMOS/BIOS reset page from where i accessed and saved the BIOS config and the PC was back up and running.
Except it was not, i can restart, put it to sleep etc, but as soon as i shut down, the only way i get it to power up again is via a CMOS reset. I have even tried replacing the CMOS battery with a new one.
Anyone got any ideas what i could try next or what may be broken. My gut feeling is, it is not hardware because once its up and running, it runs perfectly.
Thank You.
2 weeks out of warranty, i get all the good luck.

Sometimes it is best to just accept that it worked. Happy to see all is well!

I left the battery out for 30 minutes before putting in a new one with no joy.
But, roll of drums, I fixed it, I just wish I knew how.
I remembered reading somewhere that if you took one stick of RAM out and did a CMOS reset it for some reason makes the BIOS reset itself correctly.
Short of ideas I took one stick of ram out reset the CMOS, acknowledged the Memory change warning and shut down again, then put back in the second stick of RAM and Bingo. I knew it had worked, because I could switch the PC on, and it and the Keyboard both lit up to the colours I have them normally set at.
I just wish i knew how. The doom and gloom on Google, you must have blown your motherboard etc when you mention CMOS reset errors was most worrying.

When you replaced the CMOS battery (hopefully with a brand new recently purchased battery) did you leave the old battery out of the system for 15 minutes before installing the new battery? Also if this happened after moving the system, try reseating the RAM and GPU and checking and confirming that all connections are fully locked in.
