Monitor is blank

[MrBlunden]

Hi,
I have a computer that when I start, the monitor shows nothing.
When I start it, there is electricity on the motherboard.
I tried two graphic cards on another computer with the same monitor, they worked fine, and on the computer in question - monitor is blank.
What can this be? Could this be a motherboard battery issue?

Thanks!

Welcome to the forums!

Clear the bios.
Are the fans spinning?
If not, could be a bad power supply.

What do you mean "clear the bios" - remove the battery? I can't see the bios screen.
All the fans are spinning and also the fan on the graphic card.
So I should try it with another power supply?

Yes, remove the battery for 30 minutes to completely erase the information.
