Been happily play for nearly 6 weeks now and been merrily playing on my super duper new XP Dual Core 2Gb machine I got 3 weeks ago

On Sat morning for no apparent reason, I started getting Blue Screen Of Death when signing into Guild Wars.
After hours of System Restore, Driver Updates etc, the problem persists.
If I double-click the GW icon, my machine immediately goes to BSOD and reboots

Now the wierd bit, if I sign in on my wife's XP profile, I can happily play for hours, as I did last night

The second wierd bit is that I only get BSOD with Guild Wars nothing else and after the OS tries to send an error report to MicroSoft, the MS website says my error report is corrupt. Yet if I look at EventMgr, the BSOD error details and there

Any ideas ? I'll post the error details when I get home this evening. Great website and forums btw,
Many thanx in advance
