Mat replacement. boards on asus n56vz?

Question

ASUS

Good afternoon to everyone, I’ll tell you right away, the question is ... somewhat stupid, but still, good people, who can, give an adequate answer, please, laptop, asus n56vz 6gb RAM, 650m gpu, intel i7-3610qm cpu, was purchased in 2012, recently died in agony. The problem arose when I moved the bios dvmt pre-allocated from 64mb to 128mb. I usually changed it without any problems, now, after the laptop rebooted, the screen went out and didn’t turn on anymore, I sinned on the BIOS, but took it to the sc, where they pronounced the verdict in the death of the video chip, and, with all the repairs, the price rose to ~ 9k rubles, climbing on aliexpress, I found a couple of interesting options, both a native motherboard with a 2GB chip, and 4GB, I also found options from other n56vv, vm, jr series - where there are video cards 650m-750m (2, 4gb) and 760m, contacting the seller, asked if there was such an opportunity to put these motherboards on my old one, to which he replied that no one had tried, but I asked him to measure everything necessary, the answer was that they were the same in all respects, but higher in terms of characteristics, and now the question. Can I try my luck and change the motherboard this way? And what do I need to make it all work? another fan (higher power) power supply, any additional wires? Thanks a lot!
guys, in general, the mother came with n56vv on her 750m c 4gb, while the flight is normal, and I can think of the same dances with a tambourine

Answer 1

It's better to. You are not the first and not the last, the chances are very small.
Each case is designed for a certain family of boards, at most you can put a more powerful board from the same series with the same port configuration. Ask the seller for a photo with sizes and compare. You may also need to buy a new PSU.
First, try resetting the BIOS (look for the manual)
If it doesn’t help, find a wizard to do a GPU reball (1-2k)
And if everything is dull here, then look for a board

Answer 2

How is the flight with the new motherboard?
