Help! Final Fantasy XI Crashes/Hangs, then computer re-boots.

[Alex_]

Hi,

I recently just bought a new computer a couple days ago:

Amd athlon 3000+ 1.8mhz
(not sure how to check mother board, forget what its called)
222gb hdd two seperate drives (111 each)
Radeon 9800 pro 128mb graphics card
4 sticks of 512mb DIMM ddr ram

When i start to play Final Fantasy XI, sometimes i can play for a bout 5 minutes, sometimes i cna play for an hour, but eventually the screen will go black, and i can still hear the music, then it will lag and re-boot. I have all the drivers for my video card, and final fantasy is updated.

Thanks
