What are your full system specs?

CPU:
RAM:
Power supply:
GPU:
Drive/s:

What diagnostic lights come on when you power the system? There are 4 of them on
the upper right corner of the board just above the 24pin power header. CPU, DRAM
etc. A green light indicates that it completed power on self tests successfully
for that particular component (CPU, RAM, Boot etc).

Your RAM should be in slots A2 and B2 on the board. Make sure they are properly
seated in the slots as they can be tight on new boards. Don't use too much force
but enough to make sure they are fully inserted.]]> Fri, 17 Jul 2026 18:12:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=113551&PID=201818&title=b850-proa-wifi-no-post#201818 https://forum.asrock.com/forum_posts.asp?TID=113551&PID=201816&title=b850-proa-wifi-no-post#201816 Author: ztilleto

b850 pro-a wifi asrock, doesn't POST, it shows red LED, sends power to mouse but not keyboard through USB. After a few seconds it flicks directly to green light and is stuck there.

Nu signal to monitor.
Tested without GPU card, only through cpu and internal graphics.

Tested by reseating ram modules, tested with just one module in different slots.

Removed battery for cmos reset.

I'm a bit lost on what the leds are trying to tell might be the problem with the way it acts. ]]> Fri, 17 Jul 2026 17:08:00 +0000 https://forum.asrock.com/forum_posts.asp?TID=113551&PID=201816&title=b850-proa-wifi-no-post#201816
