I bet that if you make a maximum rate break turn, at 460 kts or so, that
your screen will go solid black and you (not your computer) will crash if
you continue to hold the G's (may require you to go to afterburner as your
airspeed bleeds off).
Likewise, put the Viper in a steep climb, then push hard forward on teh
stick. Keep pushing. The screen will go red.
It's not a memory problem, it's a hydraulic problem. Specifically blood flow
and gravity. As you pull positive G's (pull back on the stick, even in a
turn) you're body weight effectively increases, at the Viper's maximum of 9
G's, you feel like you weigh 9x's your actual weight. This pulls your blood
downward to your legs and abdomen (where you don't need it) and starves your
brain. Your hydraulic pump (heart) can't beat hard enough to fight the
higher gravity. So, you need to help it out a bit. A "G" suit (worn by
real fighter pilots) would inflate with air and squeeze blood back from your
legs and abdomen into your chest and head (where it would do some good). A
"hook" manuever (straining and flexing muscles) would be something you would
perform that would help as well, but nobody can defend against really sudden
unprepared G or sustained G. The "grey - out" you're describing is that
phenomenon. In real life, you lose the ability to distinquish color,
develop tunnel vision, and then go "nighty-night" until the G's are relaxed
and blood returns to your brain. There are several good UTube videos of TV
reporters getting VIP rides with the Blue Angels that show this experience.
The opposite effect - pushing negative G (push forward on the stick) is
called "red-out". It is the effect of vessels bursting within your eyes as
a result of blood rushing too fast to your head. I would guess that red-out
would be somewhat longer lasting. (As a kid I suffered an injury to my eye
in a soccer game and had blood pool in the between the cornea and retina.
My vision didn't get red, it actually went kinda green, but there ya go.)
BTW, most people can tolerate far fewer negative G's then positive ones, and
the more positive ones you endure in a flight, the harder it is to fight
against them.
Also, you may have noticed that your seat in the Viper is canted backward
several degrees... sort of like being in a sports car and tilting your seat
back to give you the "gangster lean". This helps you fight the G forces.
So, your computer's memory (including video card) is probably just find.
You're avatar's memory vault (brain) simply doesn't work so well without
blood flow, a natural result of pulling "G's too many, too fast, or too
frequently.
