I have an Asus m51bc I've been upgrading. I've swapped the mobo into a new case but now the system will not boot. Instead of just restarts over and over again. All the fans and lights come on. My keyboard is lit
Too.
The mobo I an asus m5a97 with an amd FX 8300, psu cx750m corsair, gpu amd geforce r9 280x ram is 12 GB of whatever came stock.
I reset cmos which at least lets me see the bios screen once however it says it fails to boot and will restart in 15 seconds. Keyboard mouse and hard drives are listed also. Keyboard input will not respond so I can't hit f2 to reset the bios to default.

Even worse once the 15 seconds are up it restarts but I can't see the bios screen again, instead it just restarts as it did before. I have to keep replacing the mobos battery just to get it to bios and try different USB ports. I've tried reseating jumpers on the had and power from the psu.

Any help I'd appreciate.
