Long bios POST

TommyTwommy · June 1, 2020

When booting up the PC the bios post lasts for a few minutes and the pc takes a long time to boot up and shutdown afterwards. After resetting BIOS and and clearing CMOS it worked normally for 2-3 days and now it is back to being slow again. Is this a motherboard issue? It is a pretty old motherboard from the Phenom II era. (Asrock M3N78D FX).. Do I only need to replace the cmos battery or is the motherboard gonna be toast soon?

hmm its interesting you mention the CMOS battery. When it starts taking longer is any setting changed in the bios? I would love to imagine its retraining the ram again each time but I don't honestly know if that was implemented then. Check if any settings change if it does then a new cmos battery should fix it.

Try updating the bios

Try with 1 stick at a time

If that doesn't work it could be just an aging cmos or mother board

No I didn't change anything. I just reset it, entered the bios because I had to after resetting it, restarted the pc and that was it. It was back to normal.

I'll check if there are any updates. It only has one stick currently.

Maybe one important thing to mention might be that I've also been getting a lot of error messages saying "Windows has detected an issue with your harddrive." it is a pretty new intel sata ssd so I was pretty certain it was a false positive. I've done a chkdsk, checked for bad sectors and errors but it is completely fine.
