Why is there no video signal from the computer?

Question

Iron

Yesterday I bought and assembled a new computer, before that I myself assembled and upgraded another one - I worked for 5 years. The problem is this: there is no video signal, I tried to connect it with three different cables, to different monitors and to a TV, both from the mother and from the video card - the result is the same - No singal. What could be the problem?
The post code on the motherboard hangs at "62".
I am attaching pictures and a parts list.

Answer 1

You should at least read the instructions for the motherboard ... "60" on the LED socket is not the temperature, but the bios POST codes.
Pull out the vidyuhi, turn off the hard drive and everything that is turned off, leaving only the processor and memory. Check the manual for the correct location of the memory bars and, as an option, first try with one of the bars. More on the situation.

Answer 2

on the built-in signal goes? it was on the mother with curved legs of the processor socket. the percent itself worked but the vidyuha did not start, and the other one worked. adjusted the legs everything started. another option is to update the bios on the mother
