gw.exe error?

is there a .txt file in your GW folder named ArenaNet? if so, that will have the crash details in it as well.

There was a log file named ArenaNet.log in my gw dir:
http://puddingbroodje.nl/ArenaNet.txt

Not an expert at deciphering crash dumps, but it looks like issues with textures. Now to ME, that means a corrupt .dat, but it could also be down to overheating?

What do you say, people-with-more-knowledge-than-me?

yeah i think that to, there is 1 crash log in that file and the rest are all errors with the textures, but i already reinstalled GW so the .dat file is new.

I think I've had this issue on my old computer, and I think it was due to overheating, you might want to check the fans/heatsinks on your motherboard/cpu/graphic card

Try running GW with the -dx8 and/or -noshaders command line and see if it still crashes.

I thought of -dx8 and -noshaders too. Problem is, if that does cure the problem, your graphics are going to be so shite you're going to want to upgrade anyway

upgrade to what? i got a brand new 8800gt for the graphics.

Oh dear. Maybe "replace under warranty" was the phrase I was looking for.

They're diagnostic commands. I'm not suggesting he runs his game with those commands forever it just helps determine the problem. If that solves the problem he will know DirectX is causing the crashes.

To the OP you aren't running DirectX10 by any chance are you?

Vista + 8800GT = DirectX10, so yeah i'm running Dx10

Edit:
I played Assassins Creed for 2,5 hours non-stop without any problems..

Reading through that log, it covers 4 different crashes over the course of 4 days. One is certainly missing textures (cos it says so ), but googling others leads to people who had faulty RAM, faulty RAM sockets or even mismatched RAM pairs.

You might want to check your memory.

I've done some research on the internet and came to the conclusion that Vista and Nvidia are not always compatible with each other.

i have downloaded the beta drivers and ik hope that solves it. (i also did a BIOS upgrade, just in case).

Faulty RAM would crash his other games/programs. Most likely a graphic's driver or DirectX issue. I've heard DirectX 10 has caused problems for other GW users but I'm not 100% sure. If the problem continues I still recommend using the -dx8 and -noshaders just to make sure whether it is or isn't a DirectX problem.

Hmm, again I'm not an expert, BUT... Guild Wars has often given problems to people who run other games without a hitch. It seems to reach parts of the OS/hardware that other games just cannot reach

They should use GW as a benchmark: If it can run GW, it can run anything!

It's possible but it seems highly unlikely. OP run Memtest to see if your RAM is malfunctioning: http://www.memtest.org/.

did the memtest already and resulting in nothing...

10 min ago i got a BSOD with the error:
nvlddmkm.sys

Argh. That's an nVidia driver issue. Researched it a bit and found hundreds of similar tales of woe on forums all over the internet. No absolute fix on any of them. Take a look at this ten page thread as an example - http://www.ocforums.com/showthread.php?t=518749

Certainly make sure your nVidia drivers are the latest WHQL ones - don't trust betas, unless you read in their release notes that they contain a fix for your specific problem

Interestingly, it seems that nVidia drivers with the same issue numbers can be different depending on source, that is from nVidia themselves or from Microsoft Update. Not sure how true that is, but I was having a lot of problems with my 8800GTX setup until I allowed Vista to install drivers that replaced my nVidia ones. No problems since.

now i'm justing getting BSOD with no error, just " STOP " and a row of numbers (hexa?)

but i get them randomly, when i browse youtube of playing a game, doesn't matter.

If you're getting random BSODs that would imply faulty RAM. Replace your RAM memory sticks if you can. Could be a driver issue as Snograt said too.
