I haven't been following availability very much, but there doesn't seem to be a shortage of what can be ordered online for delivery, at least. I did see items going out of stock as I viewed them when I was doing smartphone-related shopping this past weekend, but that's not necessarily going to translate to PC-hardware components. > Apart from that, option 3 "upgrade more hardware" seems to be the next thing > to consider from my point of view.

(I do > not have any answer in case of an immediate black screen.) With the single live environment I've tried to date, it's the same immediate hard system hang as I get with booting to the internal hard drives; it goes straight from the last display that's part of what the BIOS handles to a black screen, and at the same time the keyboard stops responding (including keyboard-light toggle keys). I did get a similar black screen part of the time during a successful boot to that same live environment on the old, working GPU, but not right away, and IIRC the keyboard lights kept successfully toggling during that period; it was also only a few seconds, 5-to-15 at most, vs. nearly half an hour I've waited with no change on a (hard-drive) boot attempt with the new GPU. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
