1) Don't run Matrox's speed check.
2) Do run Sisoft Sandra's 'Speed Check'.
3) Delete all partitions on the hard disk. Install whichever windows you'd like. Do not run/install *anything* matrox sent with the disk drive, or offers on their web site. Install the 4.32 drivers, make sure the 'Ultra-DMA' is checked on the hard disk inside windows. Make sure Mode-5 is enabled inside the bios.
4) Do run Sisoft Sandra's 'Speed Check', again.
