reflowing BGA with a hot air gun?

I have a laptop that is acting really weird. It's an older ASUS,
probably ten or twelve years old. It was plugged in, closed, sitting
on a table. It worked fine a few days before the problems started. The
display keeps shaking. The machine takes forever to boot up. And then
acts weird. But if I push down hard on the lower left side of the
machine it works fine. As long as the pressure is kept up and in just
the right area.
I spoke to my son about this problem because he knows more about
this kind of thing than I do. He said it sounded like a video card
problem that he and some of his computer whiz friends have run into.
Apparently the video processor can get too hot and the BGA under it
can start to debond.
He has a hot air rework tool and he said I might be able to reflow
the chip. Is this something that a rank amateur can likely do?

You can give it a try.
Here is one opinion on the reflowing.

Probably nothing to gain, but you won't loose much either.
One that old is probablly due for a change unless you need it like I
need some old dos computes to program up some old equipment.
