I have a HP Pavilion 550-115nf desktop computer running Windows 10. I changed the power supply and the graphic card. It did work well for about 2 years. But now I'm facing a big troubleshoot.
The screen of the pc freezes and I need to shutdown it by pressing the power button. After that I can't boot anymore. When I press the power button everything looks like it goes well but nothing displays on the screen. If I let the computer turned off for several hours I'm able to boot again but it freezes after 10min.
It's not a problem with the screen because it works well with another computer.
Thank you for your help,
Louis.

Even when I plug the HDMI cable directly on the motherboard I see nothing. – louisld – 2019-05-19T09:05:13.583
