"Repairing data archive" followed with crashes!

Hi guys, im kinda new to the community, but ive been playing GW for about 9 months and the thing is that i have a Laptop:

-Intel pentium M processor 760; (2ghz, 533 Mhz FSB, 2mf L2 cache);
-Ati Mobility Radeon x700;
-PCIe with 128 Vram;
-100gb HDD (disk);
-1gb DDR2 ram.

And it is an Acer Aspire 1690.

Now the problem is that since about 1, 1/2 month ive been having some problems with my GW, and almost of the times its the same problem:

Sometimes (not every single day) I enter the game, logout, and then when i enter again in that same day it appears "Repairing Data Archive", it runs, and usually (not always) the game freezes and a Blue WICKED screen appears for 1 second and then "puff" the laptop reboots itself, ive formated the laptop, ran Defrag Tool, ran norton, and i have norton firewall, ive also ran ad-ware for spywares and such but the problem remains, ive also tryed to upgrade my drivers but everytime i try to update to Catalyst 6.x it gives me an error such as VGA or that i dont have a display driver blah blah, so i ran a Mod from Driverheaven to put catalyst 6.2, but i had no luck. Now i trully dont know what to do, and i dont know if it is some issue that GW has with the graphic card or something else...

I hope u guys can help me out, thnx.

P.S: not to mention that sometimes i see weird things in game such as White Cubes....

i have the same prob and its really annoying me...1 minute im playing then the next a gw crash report...i get repair data archive every restart pretty much..i swear its this directx9 update they have done...first they RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GO up the sound..now they RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GO up the graphics engine and stability of it...congratz anet pffftt.....

If it's saying repairing data in your gw.dat file, it may be an update did not install correctly. I hate to suggest this, but you may have to re-install guildwars and Don't try and save gw.dat file (or rename it to keep it but let it create a new one. Your symptoms scream to me corrupted gw.dat file (white box's are "place holder" if it can't find the textures.

i am suddenly having glowing white tall cubic shapes where people (and only people) are.

started out with only one of them but it is now about 8-12 at a time.

also had 2 of the repair data archives.

other pc works fine.

sound the same to you?

wait til i get my Factions cd then reinstall both games and stream the remainder not on the discs?
