go for it.  the original heatsinks and fans were poorly stuck on.  there is a way to get the glue to remove in one snap if you freeze the card in the freezer.  look for the technique in this forum.....

the card is dead.  something on the card is shorting out one of the power supplies (12Vdc or 5Vdc).  could be just a fan?  you could try unplugging the fans from the board and trying it....

the cooler the better, all the way down to 0C.  below 0C even electronics can have some problems internally.  most ic's are operating temperature "speced" to between 0C and 50C with a "storage" temp from -40 to 90C etc....  the more stable and cooler the temp is kept (down to 0C), the longer the electronics will last.

I am pretty sure that MesaFX cannot run in a WINDOWED mode.  MesaFX is still you're best bet for opengl for voodoos.

My V3 worked AWESOME in my old MMX233 back in the day......  I do believe that I had one of the FIC motherboards configured for an MMX233 chip way back when by addinf a resistor across two jumper pins to "program" the voltage controller to the correct voltage and it worked SWEET.  let me know if you want me to go back over my notes and find it for you.  if you have a 233MMX chip just lying around (like i did then), it would DEFINATELY give you a boost in speed in the graphics too.

use the motherboard that it DOES run in to upgrade the video BIOS.

have you tried upgrading the VIDEO CARD BIOS???  If other cards work in the system, then the card is most likely the fault.  do you have another gf4 mx440 to put in this rig? and does the card work in another motherboard?

probably not, since your ONBOARD video card is most likely an AGP card too!  you really need a motherboard with NO onboard video to do a BIOS rewrite properly to an AGP 3dfx card anyways.  try to find a PCI elcheapo card from a friend or something.....

you're going to need ANOTHER video card to "boot" with installed at the same time the voodo card is.  any old PCI VGA card will do here.

I'm pretty sure that is just lack of memory, as my buddies laptop has a 32Meg ATI mobility7000 and does the same exact thing.  1GIG of system ram is a MINIMUM to keep "lag" away for WOW.  and NO it's NOT your connection, it IS the RAM size of your system that slows things down in the big cities..

the AGP chipset running at 2X is still just using the PCI hardware of the slot/chipset on the motherboard.  when you kick it up to 4x, is when you start forcing the AGPness out of the slot.  the AGP slot is a ONE WAY buss, the "dual" or multiple nature of the V5 and V6 had no way of telling the AGP motherboard that it was ready for more data.  at 4x, you're sending data faster than just the leading AND falling edges....... the PCIE slots are another mater alltogether.  they are a two way comunications slot and well suited to multiple GPUs.

essentially, the AGP slot from 4x and up is in a mode that doesn't work with multiple GPUs in an SLI configuration.  too much going on to keep track of between the three processors.

No , it's the MOTHERBOARDS agp chipsets that will not support a dual video GPU setup.  there was never an AGP chipset that would ever allow this configuration.

you have noise coming in from the AC line into the power supply.  try a different power strip or UPS.  sometimes old power strips can produce noise on the line.

Intel made a processor (PIII and celeron) at 133Mhz and 100Mhz FSB that reached 1.4Ghz with the Tautalun core.  with a special slot one adapter from powerleap ANY slot1 motherboard can reach 1.4Ghz.  I ahve this in my Intel 440SE-BX2 motherboard. they also have A socket 370 adapter for the 1.4Ghz PIII. runs $129 for this plus the processor.

which BIOS did you flash it with,  I think there is only one BIOS that will make that function work.....
