My girlfriend is currently trying to play Guildwars on her computer.
First try she had to update the drivers for her computer and she did. Now every time she tries to start guildwars her screen goes black and flashes

she has a radion 9800 so her computer should be able to deal with it.

can anyone give us some tips as to what is stopping her computer from running guildwars?
