New computer problems

My buddy's been trying to fix a problem. He has quite a pretty good computer 2 gigs ram geforce 9800 gtx and a dual core

Guild wars is occassionally minimizing and then dissappearing off the taskbar. Then it plays audio loops and he is forced to alt f-4 to close it. I know of one oother person with the same problem.

All his drivers are up to date and he has all the sound codec's.

He has reinstalled guild wars as well

I also get the sound loops on occassion and the game freezes, i usually have to completely reboot as crtl+alt+del don't work

If it does work it says the gw client has stopped responding

I also reinstalled gw

1. Have you ever been able to run Guildwars before on this machine without these problems?

2. Have you recently installed new hardware or software? like Video card or sound card or anything else new?

Sometimes it's best not to upgrade drivers if your computer is working fine. So maybe going back to an older driver? (If your PC was working fine before any updates to your drivers.)

Also Try this: go to start->run and type dxdiag. Once there, there should be a "DirectX Files" tab, click on that to see if there is any conflicts. If there are try reinstalling DirectX 9.0c

he's tried the older drivers. Its a new computer btw

try running GW on one core.

^What Crom said. It's becoming the first thing to try with anyGW problem on a multi-core system.

What Snog said, except I'll try to actually explain what these guys are talking about.

Many of the lock-up problems with GW (and other games) on multi-core machines can be minimized by forcing GW to run in only one CPU core. You can do this by setting the "process affinity" when you run it, but rather than go to the trouble of explaining that, and since you would have to do it each time anyway, I would recommend you Google a small app called "ForceCore", read up on how to use it, and download it.
Post here if you need help getting ForceCore to work.

Basically, you will end up with GW shortcut where the "target" line looks something like:

C:\ForceCore.exe -1 "C:\Program Files\Guild Wars\Gw.exe"

shall try it asap hope it works thanks

doesnt work still crashes running off 1 core

You say he has "All the sound codecs" and it's playing an audio loop. That may be a pointer. Disable the sound device in the device manager and try gw without sound.
Does it happen after long hours of play or short?
Does it happen every time?
Vista or XP ?

More info please..
