What is wrong with my computer?

Question

Iron

Please tell me, I have a computer, monitor and keyboard connected to the system unit. I press the power button on it - 5 long beeps sound, then a pause, then again 5 long beeps, etc. Question: what is wrong with my iron? Am I correct in suspecting that I have problems with RAM? And the question is very interesting - what exactly could be the problem? And what should I do, how to fix it?
Upd .:
I can’t say the type and model of the motherboard because the computer does not load and I don’t find it on the motherboard.

I throw a link to the photo (which should help you), I say I didn’t remove anything

It is assumed that there is no operative, but then the question arises: which operative is suitable? I know that Dimm, but I don’t know which one .... I would be glad to help.

Answer 1

Then he started beeping? what they were doing? what didn't they do? 5 long is subjective. I know that 5 short ones indicate a processor error!
