I have been having wierd random freezes since i changed a video card.

It seems to have been the video drivers.

I just updated to the latest ATI 9800 ROM and drivers.
And it seems to have stopped freezing.

so if you are seeing wierd stuff:

try these:

use version tracker to search for the latest ATI drivers
