Random BSOD's and other problems

[Will]

Hi all,

A customer of mine is complaining that he keeps getting BSOD's at random times as well as application crashes. This is on a system which I built about 4 months ago. Errors include "Driver corrupt MMPool", "nv4_disp.dll", and random stop codes. I've run the memory dumps through the Windows debug kit and it seems to suggest driver problems or an issue with "RapportMgmtServ".

I was originally led to believe that the RAM was faulty, however I've run memtest on the machine overnight which returned no errors after a few full passes. Because of the "nv4_disp.dll" error, I completely uninstalled the graphics driver and installed the latest avalible from the nvidia site, yet the issues have still continued. To try and rule out the nvidia graphics I removed the driver from the system and set the BIOS to use the onboard video instead which has had no affect on the issue either.

To try and rule out a Windows issue, I have run both the system file checker and scandisk which have found no problems on multiple run's.

Does anyone have any advice as to what I should try now?

System Specs:

• Asus P5G41T-M LX Motherboard
• 2x OCZ Gold 2GB (1x2GB) DDR3 PC3-10666
• Intel Core Duo E6700
• Seagate Barracuda 7200.12 500GB
• 650W ATX Power Supply
• GeForce GT 520 1024MB GDDR3

To completely rule out hardware error boot form an PE disk like ubcd4win or bart and let the computer run for a while.
If it doesn't crash then you know its probably the software.
Which OS is loaded? you might want to check heat and power stability.
good luck

Jogold has given good advice. Googling the GeForce GT 520 shows this card "has a history of causing sound driver conflicts."

Thanks for your quick replies.

I'll bring the PC back to mine tomorrow and let it run with ubcd4win for awhile. The system is running Windows XP Home fully patched.
