White Boxes and GW

Ok, since tech support from GW has been useless so far, lets see if this has been covered (search won't work)

I've been getting white boxes instead of people. Sometimes its female warriors, sometimes rangers, whatever. Now also, I crash a TON. I've tried every driver there is, formatted and switched OS's, ran a ton of checkers and benchmarks, nothing gives me problems EXCEPT guild wars.

I'm on -
XP 2200+
SiS 748 Chipset
AC '97 sound
1 gb (2x512mb pc2700 ddr)
x700 ATi 256mb AGP 8x/FW
80 gb 7200 rpm seagate barracuda.

This problem has become such a pain and my latest response from GW support is "Buy another video card to try" - This card is brand new and I hit near 40k on Aquamark 3.

I've - Uninstalled/reinstalled all drivers (using driver wipe program), reinstalled windows (clean format), Removed/reinstalled GW (including clearing the .dat files) ran memtest, ran aquamark.

Its not looking like I'll be playing GW much longer, but anyone who helps I'll take good care of in game .

My brother had this this problem. Check out this thread. Seems to be female Warriors more than anything else.

He still gets it but a restart of GW sorts it out. Pain in the ass, but I do believe the computer has a bad stick of RAM.

Which programs are running in the background? If you haven't tried already, disable as many as possible (antivirus, firewall) and see if the game still crashes. I had a similar problem once caused by a memory conflict with my antivirus program. Once I fixed that I never experienced any problems anymore. Also, if you crash do you get a blue screen, reboot or does it simply crash to desktop?

Interesting... the other machine also had an SIS motherboard chipset.
Make sure all your sis chipset drivers are up to date - http://www.sis.com/
Espically any pci express / agp drivers.

I have this problem aswell. I'm on an nForce4 chipset with an nvidia video card.
