B760 weirdness

[ghack]

New build, old case and good power supply. B760 Aorus Elite AX, Intel I7 12700K. First boot up to BIOS, okay. Start checking things and wireless mouse freezes for a minuet and then it crashes. Won't boot for multiple tries. cycling though ram and cpu leds landing on cpu. Check all connections, swap ram slots, etc. Boots up. Same thing. I'm in and the mouse locks up. Then cycling again. Get it up with a differnt mouse and port. Same thing. I don't want to flash the bios if it going to crash on me. Suspecting the board. Any ideas?

One thing to check the CPU socket for a bent pin. The other thing pull the board back and try it on the box it came in. If it is OK on the box then there is something in the case it could be shorting on.

Post is nearly a month old now with no replies.  Only thing I might add...  what type of RAM are you running, Brand / Model / specs?

Also what BIOS rev? 

If you start the system and enter BUIOS, then let the system sit, does it still become unresponsive?

Try booting with one stick of RAM.  Try a wired mouse, etc.
