Hey, I've just registered on the site but searched the forum for a while. I was looking for some advice on a laptop I was considering purchasing to refurbish. I am told that the laptop boots up, but there is no display on the laptop screen, or by either VGA or HDMI. The seller has just replaced the GPU and he says it worked for a few days then stopped again. I basically would like a list of possible solutions, and how likely it is that I could fix it. Keep in mind that I can't actually test anything as I don't yet own the laptop! Thanks in advance.
