Chosen Solution
I have an old GIGABYTE GA-X79-UD3 motherboard that I wanted to upgrade the RAM on. I purchased the RAM that I wanted and it was on the AVL for this board. Popped it in and it would boot but always got errors and BSOD. Ran MemTest and all was good with the ram. I then looked for a BIOS update thinking it might be that and found one then flashed the update. The flash went fine but didn’t fix the Ram issue so I used that ram in another computer. The only problem is everything works fine and the computer boots, but it takes 3-5 minutes to get past the post screen before booting to Windows. Not sure why this happened but I just want to go back to the older BIOS that worked and booted fine. When I try to flash the older BIOS it says it can’t flash an older version. Is there an easy way around this? Thanks in advance.
Hi @jeffro64, If you would like to upgrade your computer’s system without replacing the motherboard, see the Updating Motherboard BIOS page for instructions. Good day, IMO troubleshooting PC is an art, sometimes need to isolate a problem slowly to check where it went wrong, Normally, I seldom and rarely do a downgrade of the BIOS version. Some memory slots are a little near to the CPU, which when you over tighten the heatsink can cause the board to warp too much, giving a unstable connection. BSOD normally has an error code. take note of it. If too fast, download the bluescreen view from Microsoft. If you are unsure what is the error, just post here and let us have a look. The power supply can be the cause also. For this case, I would suggest you to list down the whole computer components of your PC, PSU, RAM specs, HDD, processor, graphic card, etc. Check graphic cards as it can also give issues. Boot with minimal stuff installed If possible, try with a clean install and see if it happens.
Hi @jeffro64 , Just curious, how long does it take if there is no HDD connected, to pass POST so that you can get into BIOS menus or get an error message about no bootable device found etc? Have you tried clearing the CMOS in case there are any corrupted BIOS settings that may be impacting on the boot process. Go to p.27 in the user manual to see how to reset the BIOS by #10 CLR_CMOS procedure. Alternatively, turn off the PC if on and disconnect the power from the PSU. Remove the coin cell battery from the motherboard - note the orientation of the battery before removing it, normally it is +ve on top (if it is the original battery check its voltage when it is out. If it is <2.6V DC replace it.) Press and hold the PC’s Power On button for a full 30 seconds and then release it. Reinsert the coin cell battery (see note about orientation) and reconnect the power to the PSU and turn on the PC and check
Did you check to see if there is a timer in the bios for how long it displays the boot screen? Some motherboard bios settings have a value that usually is 5 seconds but it can be changed to boot past bois screen faster, say in 3 seconds or 1 second.
