Question PC power-cycles on start up - Q Code: 16 ?

[Billy Pilgrim]

Hi
I can't start my PC. The mobo is an Asus Z-97 Pro. I've had this computer since 2014. It's a big gaming PC.

When I turn on its power, a light comes on, the Q code goes from 00 to 16, then it turns off and repeats that (seemingly endlessly?) so each cycle is only something like 3, 4 or 5 seconds long. As it is right now, I don't think it's even going to be possible to get into the BIOS.

I recently had a problem where I was getting an A2 code after changing the CMOS battery (discussed here, on Tom's Hardware), and I fixed it by defining the SSD as what to boot from in the BIOS. I may not have used the computer since then (thinking it was all fixed and ok) , and then turned it on this morning and had this cycling problem but with the Q code 16.

The computer had not been used for some time, since I fixed the A2 code problem.

Any tips, help would be much appreciated.
