Heavy BSOD problem..

Hello, I'm fairly new to the forums so I apologize if this isn't enough information. I've recently undergone a search to try and kill this wretched BSOD problem that has started 3-4x a day since I started playing this particular video game (World of Warcraft bleah). Regardless, I didn't shell out money for a rig that would crash 3-4x a day, and I want to figure out what it is so I can get it replaced. This is the system I'm dealing with:

450w Antec Smartpower power supply
A8N-SLI Deluxe Mobo
OCZ Gold PC3200 ram
AMD 4400 X2 Chip
BFG GeForce 7800GT OC

I re-installed windows and converted to SP1 as I read on the nvidia forums that similar page-fault crashes and the like were being caused by either SP2, or the NVidia IDE drivers (which I don't use). That being said, the OS is Windows XP, running SP1. Not 20 minutes into my re-drivered, re-installed, re-directX gaming system, and poof, crash again. :< Regardless, I reinstalled the debugger and used it to the best of my abilities. I've seen large, more detailed dump information but am a tad unfamiliar with it so if there's other stuff I can post up that might help someone track down my problem, please feel free to suggest.

Because I'm not all that familiar with windows debugging, I'm not sure if it's complaining about nv_disp.dll because of the symbol file, or because that's the result of the problem. There are 2-3 more BSOD's I've had the pleasure of recieving, from win32k.sys fault to page fault in non-paged area. I can post those as well when they occur next. I don't really want to chop my gaming rig up with no video card for 3-4 weeks to RMA it, so I'd really like to be sure that's the issue here.

 

The sinner seems to be nv4_disp.dll, which is part of the Nvidia Display Drivers.

What version of Nvidia Display Drivers are you using ? (Can recommend the official 81.98 drivers)

 

That's what I was worried it looked like I'm unfortunately using 8.1.9.8. I was using 8.1.4.x or 8.1.5.x a while back and having the same problem which is one of the reasons I upgraded. I guess if nobody else has any ideas that pop up when looking at the log, BFG/Nvidia are not going to be happy. Thanks

 

When upgrading to 81.98 did you uninstall the previous ones using the Control Panel -> Add/Remove and restart before installing the 81.98 ?

Else there is a long and hard way down the Troubleshooting Lane
