Mobo Issue

post #1 of 7
Thread Starter 
So my PC boots up. No video signal to either monitor. The debug LED on the mobo displays code 34 which according to manual means "CPU Post Memory initialization"... whatever that means. Almost seems like pc is stuck in boot up.

Asus live chat support was a joke. At a loss for what to do now...

Reset the CMOS if you haven't already. Also reseat your RAM. According to your code it actually isn't booting up as you said.

I would do a CMOS reset, if that fails make sure your memory voltage and timings are correct for the dimms your using.

As others have said reset the CMOS and try booting up with 1 Stick of ram if that does not work move the stick to the other slot to see if it was possibly a bad slot.

This guy was very helpful
1) pull anything that has ram involved.
2) pull battery
3) count to 5 donuts
4) replace battery
5) insert ram and vid card securely
6) connect cable to vid card (if it requires one)
7) press power button
8) cross fingers

repeat as nessasary

edit: Asus customer support, like any other support from any other company consists of humans sitting behind a computer, some are slow, some are fast... give em a break, they are paid by the hour, just like 70% of america's work force

Unplugged PC
Pulled battery
Cleared CMOS/RTC Ram
Put battery back in
Plugged PC back in
Same problem

I saw some say to try removing a RAM and video card... i wanted to try the quick stuff first. I guess more drastic measures are needed. Uggggggg

I feel for you, I know how stressing this can be. I did some searching and found this and it is well worth a try since it came from a ASUS rep.


1) Remove power from the board

2) Remove the CPU from the socket

3) Clear CMOS (important to do this with CPU out of the socket).

4) Insert one dram module in the last slot.

5) insert CPU and mount cooler.

6) Power up and see if the board will POST.

Let us know how it goes.
