Hi, everyone. Sorry for long post, but I need help and can't express myself in fewer words. :o)

I just bought a wonderful new video card for my wife's 'pooter, installed it, and it screams very loudly when power is turned on. Fans also do not rotate.

I called manufactuer and they ran me through a few BIOS tests and determined that the voltage at the AGP slot is too high. V-Core Voltage = 1.76 volts and they said it can't be above 1.6v.

I also swapped out the 600W powersupply and that made no difference.

Put the card into another pooter with a much smaller powersupply (300W) and it did not scream. So... looks as if the MB in her 'pooter is dying.

The wattage of your power supply has nothing to do with the voltage on the bus. Some BIOS-s have adjustments for voltage. This is for those who like to "overclock" their computers. Higher clock rates usually require higher voltages. Perhaps you can boot into your BIOS and find a voltage adjustment.

There does not appear to be a way to adjust the voltage. The tech support folks at the company that makes the video card seemed to think that there was too much voltage at the AGP slot.

Hmmm-- too bad. One last thing to try. If there is an adjustment for clock speed cutting that back just might also have the unadvertised side-effect of cutting back on the voltage.

Perhaps this is what caused the previous video card to fail and is causing the new card to scream. The video card tech folks said the card is designed to make that noise if the voltage is incorrect.

So, if there was any doubt, that confirms that voltage really is the problem. If the above doesn't work you now have a great excuse for getting a shiny new computer!
