Vakachehk: It won't work on the parent's laptop because the CPU seems to be in failure mode, leading to extensive freeze crashing. PS itself probably won't work as it's an ATI GPU (I think)...
Won't work on the other PC because the motherboard on that one is ancient, and while the GPU has nice stats, it's just not compatible with updates. That said, PS opens, and maybe after a while whatever bug/issue causes the blackening of everything might be fixed.
It's a new release, and new releases -always- have new issues and bugs. Look at Vista.... it was terrible. As it is now, as Windows 7 (Vista2) it's much better, after years of work.... and that's on a non-volunteer team.
