Gigabyte ga-x79-up4 won't post

post #1 of 44
Thread Starter 
Hey everyone... upset over here.

Can't get this board to post. I've tried everything I can think of. RAM in different combinations of slot. Brand new 750w antec psu. It works, bc it powers of another mobo fine.

This gigabyte board is brand new. Ans its the replacement. The first one didn't post, I thought it was DOA so I returned it... and the second one won't post either. The odds of that are slim, so im wondering *** is going wrong.


Specs:
I7 3930k
Antec kuhler 620
Antec 750w gaming psu
4 x 8gb kingston ram
Radeon hd 5450


I have the vid card installed on it. Nothing. I tried without the card, nothing. I tried with the heatsink on and with it not on. Heatsink fan plugged in and not plugged in.

Anybody have any ideas?

I read reviews about this being an easy install. .. I don't see how at this point. 2 nonworking mobos in a row. *** man

clear CMOS, then boot.

Also, could it be your CPU? very unlikely.

^Good idea, i didn't think of that, thanks.

I just went down and tried it. Removed the battery for a good 10-15 secs and replaced it. No luck. Gigabyte doesn't seem to have any other way to clear the CMOS

check ur user manual there is a jumper you should be able to remove the cap or something (not sure of the exact english word) you have to remove a cap, to slot x x _ and then back to _ xx i blieve not sure check your manual on clearing CMOS

To clear CMOS look below:

^THANK you... i will most certainly try this. Thanks for posting, it may have taken me a minute to find in the manual.

The only thing i'm worried about is that the mobo's never even been turned on for me to change the BIOS in the first place lol... so you would think they'd ship these boards fresh and ready to go. If this doesn't work tonight I'm going to have to return and get a different brand, b/c i can't risk losing time on a 3rd mobo not working properly out the box. Need to be up and running at the latest by Saturday.

Well with mine i had no such problems, i had other problems solved by bios update... I got the latest F3t from station-drivers

^okay, good to know.

Would you mind me asking what graphics card you're using?

I read a post from someone that they had to use an old ATI card to get it to post, then updated the BIOS so they could install their GTX760.

I've got a Radeon HD 5450 (can't remember the manufacturer... would be funny if it were gigabyte)... so i'm wondering if the default settings of this board don't agree w/ the video card also.

This and the CMOS are the only possible solutions I can think of at the moment. IF your booted right up as normal though, i'd really like to know what graphics card you're using. Also... did you use the suggested RAM slots?

If it won't post at all, you could try hooking a speaker to the 4 pin speaker header on the mobo and see if you get any beep codes. It might point you in the right direction, e.g. bad CPU, bad RAM, unrecognized video card, etc.

At this point, with limited information, it sounds like a bad video card, bad RAM, or bad CPU. You will need spare parts to diagnose further. PSU and motherboard can probably be ruled out.

I'd also attempt powering the thing up OUTSIDE of a PC case. Just a motherboard, PSU, video card, and ONE memory DIMM in the slot recommended by the motherboard manual for 1 DIMM operation.

Hey... I actually ran into one of your old threads about this exact same board, where you were having problems getting it to fully post. (At least yours turned on fully, if only for a few secs lol).

Did you ever get that solved? If so.. how did you do it? Was it clearing the CMOS that fixed it? Please share if you can remember lol. It looks like it was 2 months ago.
