Why Does My PC Keep Rebooting Before BIOS?
Your PC keeps restarting before BIOS, mainly due to having faulty RAM. On top of that, a defective power supply, overheated processor, and virus infection can cause your machine to restart before BIOS. Sometimes, changes in BIOS settings can also be the reason behind this issue.
Let me explain them in the below section.
Here are the reasons why your PC keeps rebooting before BIOS:
Faulty RAM
Problems with the RAM can induce various issues, including sudden and recurring reboots. It could be that the RAM itself has problems or dust has collected on the RAM slot.
If you notice that your computer is about to restart and you hear a beeping sound, then this is a good indication that the problem has something to do with the RAM.
Defective Power Supply
If you determine that there is no fault with the RAM, the power supply unit is another area to look into. Just like the RAM, any problems in the power supply can cause the machine to restart again and again.
Overheated Processor
An overheated processor is one of the most common issues associated with a computer that keeps restarting. There are several reasons processors can overheat, and one thing is clear – when it does, it brings a bunch of problems. And, yes, an overheated processor can be the reason why a computer reboots randomly and repeatedly.

Virus Infection
This is the most common reason behind a computer keeps restarting. When this issue happens constantly, even if you have checked the other factors listed above, then a virus could be the real culprit.
If you are having problems due to virus infection, turn on the boot time scan feature. This will automatically perform boot time scanning the next time your PC restarts on its own. This feature will also delete the viruses before they load.
Changes in BIOS Settings
BIOS is a series of instructions that tell your computer how to load its operating system once it’s powered on.
The software loads from a ROM on your motherboard, but it also has some configurable parts, which sometimes get corrupted.
Faulty CPU
CPUs are highly durable components that last years without any issues. Sometimes, the CPU’s heatsink and fan are likely to cause problems since they’re much less reliable.
