More DFU problems - Tried everything?

Hello, I have had a lot of problems with my lovely M6. But now I have got the white screen problem (again), and this time I can't manage to get the DFU tools working.

*I'm sure I'm pressing the right buttons, all the time.*

I've tried on three different computers, but still without any luck:

1) Ferrari 1000, amd64, winXP: Driver install okay, downloading hanging. My opinion is that this is a hardware compatibility problem.

2)HP, intel, XP: The computer just gives me a popup, that says it's something wrong with the device, trying to use a windows driver, can't get any option to install my own driver.

3)Dell XPS, Intel Centrino Duo, Vista: I don't get any device in explorer (no built in DFU working), but on the other hand it asks me for a driver, but I can't find any DFU tool driver for vista (people seems to get the "vista dfu" working out of the box.)

I do appreciate any help,
thanks in advance.

Edit: Sorry for all the english grammar problems...

See the picture of the problem, attached...

I've now tried installing the XP driver on vista, but then I got the same problems as at the picture (attachment), but with four blue dots.
