The fans are spinning, but the image is not displayed on the monitor, what is the reason?

Question

Iron

Hello. I need your help, because I don't know what exactly is the reason.
My video card gave up and left for another world with a chip blade (I already encountered the problem with the old video card, but somehow miraculously everything was solved and the computer just turned on as if nothing had happened), I decided to upgrade. From the old mat left. board (H-Joshua-H61-uATX socet 1155) and power supply (fsp 700 watts). Everything I've bought has been tested and is working. I connected everything, and then it's a bummer, all the fans are spinning, there is no image. Started checking.
Took out the battery from the mat. fees, put everything back the same.
I took everything out, except for the power supply and the processor, I turn it on, the speaker is silent, a black screen.
I started to check the processor, it was heating up, plus I checked it before buying, but still I installed the old one, everything was the same, except for one, the speaker without RAM began to squeak. I installed RAM, nothing has changed, only the speaker went silent, the cable from the monitor is connected to the motherboard, before without a video card it gave out an image now not with the old processor, not with the new one, a black screen.
Well, I started checking the RAM, put the old one, nothing has changed.
I thought bp, asked a friend to bring a bp (serviceable, working), connected, nothing new.
Please tell me what is the problem, I tried everything, nothing helps. I understand that something is wrong, but I don’t know what exactly, maybe you have encountered such a problem. Sorry for such a big text

Answer 1

If all components are checked, then the problem is probably in the chipset mat. fees

Answer 2

Could this be due to a dead bios battery?

Answer 3

There is very little input for a sane answer.
It is not indicated whether the new video card is discrete or integrated into the processor, there is no configuration as a whole.
If there is a built-in one, then if you used a discrete one before, there may be a video output on the motherboard that went through the beard, and it went a long time ago - you just didn’t know.
If it is discrete, then options with a chipset or the processor itself are possible (as an option, when changing the CPU, the leg was crushed somewhere, as far as I remember - they are on the motherboard, so checking the processor separately will not give anything). Or, for example, they damaged the video card connector when poke, this can also happen.
