GreyFox: your SOLUTION isn't true !
why ?
because when you got a HEATING problem !
it's either your video card or your CPU, but both crash the WHOLE machine.
only his internet Crash !
so the problem cannot be over-heating !

juggernaught:
if you tryed all my solutions then you clearly have a FILES problem and the only way to solve it is by REINSTALLING windows or FORMATTING and REINSTALLING !

anyway, have you tryed the DOWNLOADABLE version ?
if yes and still having the problem then it is clearly your computer !
it's really annoying, but you'll have no choice !

EDIT:
i just thought, it could be your ISP !
but if the rest of internet works but not the site then it is a problem to the shockwave plug-in.
you'll have to try to REINSTALL the plug-in.

just think a computer is very capricious, in lots of case the computer work fine, but has LOTS of trouble going underground ! meaning the computer may be running fine and still have corrupted files or even program who access the same files at the same time. causing the computer to have INTERNAL Error !

i doubt you can see what's going on in the CPU while your computer run !
that's what i was talking about.
if you got a problem like that then the problem can only be solve in one WAY !
by reinstalling COMPLETELY.

i know what it includes and that's why i telled ya to try REINSTALLING windows over your old one first. that way you don't lose a single thing.
but still if the problem is given by another program IE for an example then even reinstalling can not solve the problem.

anyway...
never consider that your computer isn't the one who cause the trouble cause in 99.9% of the case, it is him !
from what you say, it is YOUR computer who is the problem.
