A Desktop PC built from off-the-shelf DIY parts, rather than a prebuilt from a major manufacturer. These can also be built by an SI using off-the-shelf parts.

Computer stuck on BIOS.

One day, I loaded up my computer, when everything froze. I shut it off using the physical shut down button. Next time it booted up, I was stuck on the BIOS screen. My storage isn't being detected, but the part itself seems fine.

Hi @dantheking2021

You could try a full power refresh just in case the BIOS has become corrupted for whatever reason preventing the PC from starting properly.

Disconnect the power from the PSU, remove the coin cell battery from the motherboard, press and hold the Power button operated for a full 30 seconds, reinsert the coin cell battery (+ve on top as marked on the battery) reconnect the power to the PSU and turn the PC on and check.

If it now works OK it may pay to check the voltage of the coin cell battery to make sure it is OK. If is is <2.5V DC or if the battery is >4-5 years old replace it. Type number is on the battery Do this with the PC turned off and the power disconnected from the PSU

If it still doesn't turn on OK and if it only gets to the BIOS menus - is there an error message e.g. no OS or similar or straight to the menus

Storage drive not being detected in BIOS indicates that the HDD (or SSD) has failed or that there's no power available to the HDD (or SSD) as the BIOS cannot communicate with the HDD(SSD) control interface.

What do you mean when you said that "...the part itself seems fine."?

If it's a HDD and you can hear it spin up when turning on the PC this proves that power is available to the HDD but not that the BIOS is communicating with the HDD.

If it's an SSD then there's no audible (or visible) indication that it is working even partially.

You could try installing the HDD/SSD in another PC and check if it is detected there or you could try running a Linux distro (Puppy Linux?) from a USB flashdrive and when it loads (do not select install just "view" or "try") get into Terminal mode and run commands : smartctl --all /dev/sda and check if the HDD(or SSD) shows up.

Sometimes Linux will pick up that the HDD/SSD is there when the BIOS can't for whatever reason.

Probably your battery on your mainboard will be empty. When you start your computerit looks to the bootpart on your harddisk. When you have replaced your battery, you have to find your harddisk manually. than your pc will start up well.

It's not a laptop, doesn't have a battery.

Hi Dan! He probably means the BIOS battery. It's the 3V coin cell battery on the motherboard. It's worth a try to check this one out!

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

Yes, it's a small battery
