Title: P67A-UD7-B3 POST/Power On Problem
Post by: NuQQ on June 07, 2011, 12:47:57 am
Hello everyone,

I just finished putting my new system together and it won't get to OS installation. My POST sequence stops at 89h (LED POST Indicator). Which in my motherboard's manual states:
"1. Assign IRQs to PCI devices
2. Set up ACPI table at top of memory."

So far I've tried different PCI Slots for my video card and I've removed my wireless NIC completely.
I can rule out the faulty video card since I was working flawlessly in my old system 30minutes ago.
Tried AHCI and IDE SATA Mode, I know this is random but I was trying to get it on AHCI right off the bat.
I've tried booting with a single stick of RAM in the first DIMM Slot.
Both my Hardrive and my DVD Drive are detected in the BIOS in the right slot.
I've cleared CMOS already.

I think I've covered everthing if ya'll need more information, ask away. I'm out of options here, help me out :)

Thanks,
Nuqq.

Hi and welcome to the Gigabyte Forum.

I don't suppose it is anything very much that is causing you problems we just need to do a few checks etc to pin it down. What ports do you have your drive connected to ?

In fact a list of your hardware wouldn't go amiss.

Try clearing the CMOS by folowing these instructions exactly.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.
