since half a year my computer started having startup problems, the pc shut itself down once or twice during the startup of Windows before it would act normal.
Hoping it wasn't the power supply, I updatet the BIOS using a USB-stick and the program in the BIOS.
After the bios update was finished, the PC rebootet, only it didn't boot correctly.
After that, when I start up my PC it stay's on for about 5 seconds and shuts down itself after that, not even enough time to enter the BIOS again.
Hope there is anyone who can help me!
