The computer turns on, there is no image, what should I do?

Question

motherboards

I decided to put a fresher processor on the motherboard and this problem appeared. When you turn on the computer, the cooler starts spinning, but the image does not appear on the screen, the speaker is silent.
There is no such problem with the old processor. I am sure that the fresh processor is working.
But once the image appeared on the screen, I decided that everything was fine, turned off the power, applied thermal paste and installed the processor, but again it did not produce an image.
BIOS update did not solve the problem.
Changed the battery, changed the RAM too.
Processor - Intel core q8400
Motherboard - Foxconn 945g7md-8ks2h

Answer 1

Take the computer to a service center. Probably a problem with the video card, if it is possible to ask a friend for a video card, it is worth doing it. If there is an integrated video card in the mat. board, it is worth switching the display output to it.
