  1. I get Stop (BSOD) errors with reference to the video card drivers, three so far in relation to the main driver, one in relation to the Mini VDD driver, and 1 with no driver listed. 5 errors are as follows:

    nv4_disp.dll address BFA6AE83 base at BF9D4000 Date stamp 44dd4897. Stop 0x0000008E (0xC0000005, 0xBFA6AE83, 0xA54E797C, 0x00000000)

    nv4_mini.sys - Adress B95C6EFB base at B93D1000, Datestamp 44dd49d8. Stop 0x00000000 (0x000000C8, 0x00000002, 0x00000000, 0xB95C6EFB)

    My current system:
    Brand: I made it myself (homemade)
    Motherboard Brand: Gigabyte SLI 550 (GIGA GA-M55SLI-S4 NF4 SLI AM2)
    Motherboard Chipset: NForce 4.
    Processor Type and Speed: Athlon X2 dual core 3800+ (CPU AMD|A64 X2 3800+ AM2 2x512K)
    System Ram: 1Gx2 CORSAIR TWIN2X2048-6400
    System Bios Version: m55sli-s4_f4
    Driver Version: Forceware 91.47 (6.14.0010.9147)
    Operating System: Windows XP
    Power Supply: PSU ENERMAX | ELT500AWT 500W RT (22 Amps on the 12 volt rail)

    Comments: If I leave my computer on during the night seems like 8 hours+ of the computer being on is when I get my blue screen Stop errors. Seems like I only get blue screen stop errors when I am running a game using the video card. When I am not running the game and leave the computer on for extended periods my computer just simply freezes and gives me no blue error. My dxdiag says that the approx. total memory is 512 MB. I thought my video card was supposed to be 1 Gig. Does this mean my motherboard cannot handle my video card because it is top of the line? Also I read in the manual for the video card that it requires a minimum of 450W. My power supply is 500W (22 Amps on the 12 volt rail). Could that be a problem? The memory that I have is on my current motherboard's list of compatibility, but it is not the recommended memory.
    I ran memory scans on my memory for more than 8 hours straight. No errors. If it is a motherboard problem, which I assume it is, I am going to buy a different one. Are there any motherboards you could recommend for my setup? If not maybe more change is needed. I just want to have a stable computer.

    I had the same file trip up my rig (nv4_disp.dll) with my 7900GTX so I uninstalled the 91.47 drivers, used Driver Cleaner Pro under Safe Mode to completely clear out all drivers and then reinstalled. I didn't get error again.

    Your card is supposed to have 1gb - what does Windows recognise it as having? (Right click on Desktop, Properties, Adapter). Was this a replacement card or added to the system when built? If it's a replacement, then definitely use Driver Cleaner and reinstall.

    Other than that I would suspect power supply, memory or overheating. What are your temps like after a gaming session or running for 8 hours/overnight?

    Some things to try, but unfortunately that's all I can suggest other than emailing Gigabyte and ask if the board can handle the 7950.

    Blue screen with nv4_disp

    I got the same message when I woke up. So it seems we're having the same problem, however I just reinstalled the newest drivers yesterday and this happens today. So I wonder if it's as simple as reinstalling the drivers. I too have the GX2 just mine is made by EVGA. So i have to wonder if this is just a lemon card with a comon issue that is just not known yet or some wierd conflict with a component in our machines. Has the driver reinstall worked for you Hoopfan187 ?
