So I have this problem when I restart my PC, it fails to post and the fans keep spinning hardly. The only solution is to press the "Clear CMOS" button on my mobo, then the system will boot normally.
I am kind of a person who never shutdown his PC and keeps it running for months, and upon restarting the PC for installing new software or updates, it hangs and fail to post with Q-Code "B1" and the DRAM led switched ON.
This made me believe that the problem is from the RAMs, so I reinstalled them and updated the BIOS to its latest version. yet the problem still exists.
However, if i restart my PC frequently (after clearing CMOS on the first post failure), the PC boot up normally. But if i left my PC running for more than 3 days lets say, upon restarting it fails to post I have to clear CMOS again.
My PC is running on stock speeds, although i did some CPU overclocking in the past.
XMP mode is enabled for the RAMs, the rest is set to auto.

I hope that I made it clear and sorry for many grammatical mistakes.

Regards,
Me

Clear your CMOS and test your system at stock defaults for me. No XMP.

I have already tried that! I have also tested every single stick (Placing only one at a time) and the system always post. the problem is when I leave my PC ON for days and restart, the PC fails to post with Q-code "b1" and solid red dram led.
This problem is recent and i never had it before (my PC is 1.5 years old).

any suggestions about what is going wrong ?

Does the issue possibly coincide with the system trying to do a Windows update?

I experienced the same frustration - updating to BIOS 3101 (stock - no mods) resolved it.

Hey,

I've just created another thread concerning this issue. Mine was due to a usb compatibility problem (playstation 4 controller plugged = b1).

I've updated my BIOS from version 2101 to 3202 (Latest at that date). Will report back if the problem still persist. 🙂

Don't think so. Anyway I've updated my BIOS from version 2101 to 3202 (Latest at that date). Will report back if the problem still persist. 🙂
