My Dell won't boot up, just a black screen as others have described.
It's been diagnosed as a faulty motherboard, but Dell want over £450 to fix it.
I can get a replacement part myself for £200 and my question is this: is it easy enough to replace, or will I make things worse by attempting to do this myself?
I've got a bit of experience with standard desktops, but not replacing parts on an all-in-one.
