I bought exactly the same memory bar as it is now in the block, the same manufacturer bought the same characteristics from two different sellers, but the computer refuses to even turn on with any options for installing memory in any slot of one or with the old memory squeak error. do I need to change the motherboard? I also wanted to install a video card, but now I'm afraid to take it. Thank you.
