I recently obtained a Geforce2 MX400 AGP card to replace my old Voodoo Banshee PCI card. I thought I would test it out in Win98 before installing into WinXP.
Got the new card installed okay and running with the latest nVidia drivers but my PC started behaving very strangely. The power to the floppy drive unit became somehow disconnected and the drive would not work. In fact, as far as the rest of the PC is concerned, the floppy drive did not exist!
At first I thought the floppy drive was defective so I tried another one but the problem remained. Then I found myself locked out of Windows. I restarted the machine in safe mode and found the MX400 listed as a standard VGA card. I tried to reinstall the nVidia drivers but was told that there was no MX400 card present!
After removing the MX400 AGP card and reinstalling the old Voodoo Banshee PCI card the floppy drive immediately started to work again and everything else was okay.
It left me wondering if the PSU is defective. Could the use of a faster AGP card that presumably draws more power be causing this problem?
(I am using a Gigabyte GA-7ixe4 M/B with 1 AGP (2x) slot, 5 PCI slots, 2 ISA slots and AMD 751/756 chipset)
Thanks, Alan
