ECS Elitegroup K7VZA 1.0 Specifications Manual Drivers BIOS OEM Reviews/Links The K7VZA REV: 1.0 is a retail Socket A (462) motherboard built by ECS Elitegroup. The K7VZA REV: 3.0 is a retail Socket A (462) motherboard built by ECS Elitegroup. The older K7VZA REV: 1.0 has an orange colored PCB with VIA KT133 (VT8363) soldered on it instead of VIA KT133A (VT8363A) and lacks the support of AMD Athlon XP and Duron (Morgan). You also may try.

I've been using a Nvidia TNT2 M64 video card for a while now without any problems. A couple of days ago I decided enough is enough, so I've upgraded to an Abit Siluro GeForce4MX440 card. That's when the problems started. The system would crash anytime an OpenGL or Direct3D game would play, and even in Windows. The blue screen would always mention the Nvidia driver, although the event viewer will list an ACPI error (writing where it's not supposed to). Well, next I went and found there is a BIOS upgrade to fix the ACPI error, so I downloaded it and installed.

It made no difference. Next I though well, maybe reloading will solve it.

It certanly helped, but it will still crash. Same video driver error.

I'm running out of solutions. I've tried disabling the BIOS shadowing, lower the AGP value, disabling almost everything in the driver panel. I've never had any problems with the older card. Am I looking at a bad card? I did notice there I can increase the 'driving current', whatever that means, but the manual gives no info on what values to put. DA is the default. I'm running a Athlon 1G, 512MB ram, 20G Maxtor drive, 60G IBM drive, ECS K7VZA Rev.3 board, Abit Silluro MX440 video card, NIC, CDRW, DVD.

There are no other peripherals. I haven't really paid attention to the actual memory value on the blue screen of death, but they look the same all the time. Sometimes the game itself just quits.

Sometimes the whole system freezes. There are however no no entries in the even viewer other then 'The system has restarted from a bug check'. Very descriptive. I'm running XP Pro, I probably failed to mention that. I suspected it might have been, but you were so thorough describing what you tried I thought you may have left that step out. Anyway, if you bought it from a local store, try to exchange it, it may be faulty, or try the card in another machine if one is available. I hate it when something that you are really psyched for makes your machine crap out.

I was going to say something about exchange the Nvidia for something else, but didn't want to turn this into an Nvidia/Ati debate. I think we have a thread for that somewhere already.

I got it from McGlen, there should be no problem getting it replaced. I'll probably try to exchange it for an ATI card, but I've heard those have their own 'share' of problems also. Somehow I'm leaning against a hardware issue mainly because it got a lot better after I reloaded XP.

Right now I can play Maxpayne for perhaps 40 minutes, before it would run for maybe 2 minutes. Since no other hardware was changed or altered I'm leaning toward a driver issue. I was told that on older version of the Nvidia driver is better, but I forgot the number. Regarding the MB, does anybody know what values I need to put in the 'driving current' box to increase the current?

I believe that will increase the voltage to the video card. I did a bit more research and found that my problems may be related to a lack of voltage to the AGP bus. 'DA' is the standard value (if set to auto), but I've read some posts in which a higher driving control value needs to be used when using a Silluro MX card, although different values were given. Some suggested EA, EF, FE, EE, and FF. I'll start low (EA), then go high (FF), and see what happens. Since the problem occurs 99% of the time when the card is worked really hard (during gaming), a lack of voltage will make it crash.
