Hi all, problems with the b450.

MB - b450 steel legend
Apu - a6-9500e
Mem - corsair 3200 vengence pro rgb.
Psu - cx750

Not connected atm GPU - 980ti

Just trying to get the mobo to boot up etc just so I can update the bios to take the 3600 but having big problems with posting.

Fans and rgb all light up on start up however it just sits there and restarts every 20/30 seconds or so.

I've done a search on the forum but no answer seems to resolve it.

I've removed the cmos battery, tried all combinations of memory in the slots. Tried with and without the gpu, unplugged ssd and Hd etc.

Any ideas?

Many thanks
