Accessing the BIOS is a necessary aspect of using any computer. It allows you to change settings, make necessary tweaks, or improve performance by turning some settings on or off. Every PC has a BIOS of its own kind, as it depends on the motherboard.

However, there are times when PC won't boot to BIOS. So, what do you do in that case? Today, we're going to analyze what causes this. Then we'll talk about a few ways you can fix this issue. So, let's dive right into it.

Why My PC Won't Boot to BIOS

If your PC won't boot into BIOS, then likely it's there is something broken in it. Or, some settings or tweaks are out of the way. The BIOS settings are made to help you troubleshoot, tweak, etc. So, if your PC cannot enter BIOS, then there could be a few issues, such as:

  • You're pressing the wrong buttons, i.e., F2 instead of F10, F10, or DEL
  • Your motherboard's CMOS battery has gone bad
  • RAM or other hardware preventing it from booting into BIOS
  • The keyboard is broken, and the BIOS key doesn't work
  • Broken or missing BIOS jumper on the motherboard
  • The power connector isn't seated properly
  • Your motherboard is broken
  • The BIOS chip on your motherboard has gone bad

If your PC won't go into BIOS, then it's likely it's one of these issues. While you can't fix your motherboard, you can send it for RMA (Return Merchandise Authorization) to repair it. However, you can still try other fixes. So, let's keep digging to find out how to fix this problem.

Sometimes, your computer will be stuck on the BIOS splash screen. If you are in such a dilemma, you can refer to the following article for help.

Fix 2. Remove BIOS Battery to Reset CMOS

The next step is to pop your PC case open and try to reset the BIOS battery. However, you must ensure you're doing it right, as simply removing the battery may not reset your BIOS entirely. So, here's what you're going to do:

Step 1. Shut down and unplug your PC from the wall outlet.

Step 2. Open your PC case and locate the CMOS battery.

Step 3. Press the battery latch backward until the CMOS battery pops out.

Step 4. Once the battery is out, wait for 10 seconds.

Step 5. Pop the same or a new battery back in.

Step 6. Done.

This will reset the BIOS in its entirety. And once you restart, you will notice the notification on your BIOS screen saying that the BIOS was reset.

Fix 3. Troubleshoot the RAM Sticks

You can sometimes fix this issue by plucking your ram out and plugging them back in. So, if your BIOS is not working, it's likely that one or two of your RAM sticks are preventing that from happening. Here's how to ensure that's not the case:

Step 1. Open your PC case.

Step 2. Unplug your RAM sticks.

Step 3. Use a pencil eraser to clean the connectors.

Step 4. Plug your RAM back in.

Step 5. Try to turn on the PC again.

Step 6. Done.

This will most likely fix the issue of your RAM not allowing your PC to go into BIOS mode.

Fix 4. Fix the Faulty Power Connector

While you can't fix your power supply's faulty power connector, you can ensure it's seated properly. If you've made any recent hardware changes, then it's likely that this power connector was unseated or disturbed. Here's how you're going to do that:

Step 1. Locate the ATX 24-pin connector on your motherboard.

FAQs on PC Won't Boot to BIOS

1. Can BIOS be broken?

Yes, it can. A BIOS is a storage chip on your PC's motherboard containing the motherboard's firmware. If that chip is burnt or broken, the BIOS will not work. And that BIOS is powered by the CMOS battery when your PC is turned off, so a broken battery can also cause the BIOS to malfunction.

2. Can malware destroy BIOS?

Yes, malware can corrupt or delete the BIOS file from the chip. As a direct effect, it'll render your computer unusable until the BIOS is fixed.

3. Why is my PC booting to BIOS, not Windows?

If your PC is booting directly into BIOS and not Windows, then it's likely that your storage settings are out of order. So make sure you head into Boot options and prioritize the device with Windows on it.

4. What causes BIOS to fail?

Various issues cause the BIOS to fail. Sudden power failure is one of the most common reasons BIOS chips fail. Other reasons include technical malfunction, malware attacks, or users accidentally bricking the BIOS when trying to update it.
