Black Screen with stuttering sound

System Spec:
Athlon 64 3000+
ATI X800 XT PE (latest catalyst drivers 4.12)
1024 pc3200
MSI k8n neo2 platinum (latest nForce system drivers)
Creative Audigy 2 ZS (latest drivers)
Antec Truepower 430 watt power supply. (25 amps on the +12v rail, only running one HDD, and a CDRW along with the other stuff, this is way more power than I need for sure)
Windows XP SP2 with all hotfixes.

I've done a ton of testing on my system to check for stability. Prime95 for nearly 24 hours (heats the CPU up like mad), memtest to check for memory errors, looping demos in games to generate heat in the video card. Everything has run flawlessly. I can play half life 2, or World of Warcraft for hours with no problems.

The problem is, that I've been able to log into the game roughly twice, crashing out pretty horribly both times. The screen goes black, but the machine stays on, sans the monitor, which goes to sleep. My system is solid as a rock. The times I haven't been able to log in, the program just gives me the "SL has crashed, do you want to send a tech report" I click yes, tech data gets sent, and nothing happens after that. reader_sl.exe remains in the active processes list taking up just under 2 megs of ram, but apparantly not doing anything at all.

What gives? I'd like to check this game out but it would appear that I'm out of luck.

Ok i had something similar to my radeon way back, what i did was
no AA, FSAA , turned off that restart video thingie when frozen eh i forgot what it was named again.

Runned in window mode and it was gone for me.

Im not using that card more tho, or i would know what that thingie's name was again
