Z68XP-UD3P Intermittent Posting Problems

[richandzhaoyan]

Hi Guys,

First time poster and first time pc build so any help very much appreciated.

I have built a system around the Gigabyte Z68XP-UD3P mb. I5 processor, 8G Ram, SSD for os, twin nvidia 560ti's in sli.

I put the system together about 4 months ago and have been plagued with niggling problems ever since. Plenty of random BSOD's (usually when the system is idle) but the problem I have now is with the BIOS not posting, it freezes randomly at diffferent point in the startup.

I think I have pretty much sorted the BSOD's - I have put this down to the mb not recognising the RAM correctly. It is Corsair 1600mHz and the BIOS was only recognising at 1300. I have now set this manually and also upped the voltage for the RAM manually too. This seems to have settled Windows down and no more BSOD's for awhile.

The problem I have now is that every now and then the pc simply will not go throught the post process. It gets stuck sometimes after detecting the RAM, and other times it will detect the first 2 IDE ports, which the Hard Drives are attached to and then tries to detect other IDE drives but comes up with a series of "L"'s all down the left of the screen before freezing again!!! It's pretty bloody infuriating..... to say the least.

Being a first time builder I unfortunately dont have any other hardware to swap in/out for testing and alot of reading has led me to doubt the RAM, power supply, SSD, etc, etc...... but tbh if I was to go out and buy any new parts I would start with the Motherboard!!.

The question is, is this where the problem lies?? I have read about cold boot problems with this motherboard on the internet but mine does not seem to be going through a "boot loop" sequence, as such, just a no boot!

I cant see as any of the other parts are to blame as it happens at different stages of the Post process and when it does Post correctly, windows allways loads and I have no problems running any software/games, etc..

Sorry for long post but thought I would try and explain it as fully as possible. Any thoughts/advice would be very much appreciated.

TIA,
Richard

I would pose these questions to Gigabyte support and see what they say. Since your motherboard is in warranty, they would likely have you RMA it, or ofter some other solution that has not made it to the internet yet.

You might be having problems in the BIOS itself. A good idea would be to download a fresh copy of the latest BIOS for your board available at the Gigabyte Website.
Get it onto a Flash drive and update the existing BIOS or reflash it.

A point to be taken into consideration at the time of doing this would be to have the rig with it's minimum requirements on, meaning, just a single stick of RAM, a Single GPU and the SSD.
I say this, because we have not yet come to a definite conclusion that the Mobo has a problem or the stuff on it has a problem. Thus flashing it with it's bear minimums will eliminate the other possibilities of getting into a bigger mess if things get screwed.

Hi Guys,

Thanks for the replies,

I have flashed the BIOS up to the current latest release. It didn't seem to make any difference either way to be honest. I might as you suggest try to flash to a different version, with the minimum components attatched and see how that goes.

I have not as yet been in touch with Gigabyte, basically because as this is my first build and with all new components, I simply was not sure where the problem lies. I think I will get in touch with their support though as I am becoming more and more sure that it is a mb problem. Maybe they can help to rule it out either way.

Thanks again for your thoughts,
Richard.
