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. (Solid RED)
This made me believe that the problem is from the RAMs, so I reinstalled them and updated the BIOS to its latest version (ver. 3202). 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.

With or without XMP the problem still exist. Everything else is set to auto.

Edit #1: Removing and installing all the RAM sticks is an alternate (temp) workaround to get my PC to post. (However, clearing the CMOS is much easier and yet the problem still exist). My assumption now is "If all modules work alone than logic conclusion is that motherboard make problem with communication when memory is in quad channel or some of DIMM slots is not good. "

what do you guys think ?

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

Regards,
 



I have already tried this. I've got another q code 76 with cpu led is solid red. As always, the temporary solution was to clear the CMOS.
