Does the system stop working after adding 4 sticks of RAM?

Question

RAM

Motherboard LGA775 max. Memory 16 GB.
Now it costs 7, 3 2GB each and one 1 GB each.
When I change the bar from 1 GB to 2 GB, the computer stops giving a signal to the monitor, and it goes out, I tried it with the computer turned on, it just wrote down
All the bars work, they are identical, all the connectors work , swapped places, Everything WORKS, but it’s only worth putting 8 GB, then everything, goodbye

Answer 1

Motherboard LGA775

there is no such motherboard, it's a socket. Read in the docks at the motherboard, how much it supports operatives, and how much the processor has. I didn’t understand who you wrote about.
And in general, it’s not very clear what is happening there, reformulate the question normally

Answer 2

Does the computer freeze and shut down before enabling bios or before loading the operating system?
