Desktop switches itself off when it gets to the bios screen

Check the Computer for Overheating
If your Windows 10 PC shuts down abruptly, the first thing I would recommend you do is to check if it's overheating. Overheating could be due to damaged or underperforming fans, poor ventilation, dust, and inadequate power supply.

This May Work,

Hello, Sudden shutdowns during the BIOS screen can be caused by various issues, including hardware problems or corrupted BIOS settings. I recommend resetting the BIOS settings to default or seeking professional assistance if the issue persists.
