Guild Wars Causing Serious Error

I've been playing guild wars for some time and have just recently been experiancing extreme problems with Guild Wars. The game has been causing my entire computer to freeze up to the point where I cannot move the mouse or type in any keys, and everything stops moving. I sent an error report to Windows about it, and they told me to disable my Hardware Acceleration and disable wire combining.

The computer itself stopped freezing, but Guild Wars no longer plays, because disabling hardware acceleration also means disabling Direct X and the like. When I enabled it again, the problem persisted, and is now to the point where I cannot even type in my password and get on a character before my computer starts to freeze.

I've looked into the possibililty that the trouble may be due to an out-of-date computer, but that's all but impossible since this computer has the newest graphics card, operating system, and runs the fastest kind of internet in existance. Anyone else been experiancing this problem? If so, is there any way to fix it without totally replacing the computer?

8800GTX KO 768MB, Vista Ultimate 64bit with a 14Tb/s interweb connection?

Seriously though, it would help if you posted your specs rather than saying it's got the newest eveything. That way we could offer some advice rather than attempting to guess what could be up.

Also, I forgot to mention that this is a 2 month old computer, I had an old one that used to play Guild Wars fine, this computer is newer and has a better processor than the old one. Not exactly sure what kind of hardware the computer uses, or if it's the newest. However, I know for sure that it's better than the previous computer. I would appreciate it if you could tell me how I find all of this out. All I can get for you for now is this:

Windows XP
Home Edition
Version 2002
Service Pack 2
Intel Pentium 4 CPU 3.40 GHz
3.40 GHz 1.00 GB of RAM
