Here's a problem that's had me stumped for over a week now, Vista doesn't work with my 3007WFP if I use the nVidia drivers. I see the green Vista progress bar, but I lose signal at the splash screen.

I've tried a whole heap of things to identify the problem.

- Other DVI socket (no picture)
- Older driver versions (no picture)
- Monitor cold boot and reconnect (a corrupt image)
- Nvidia control panel settings (no picture)
- Motherboard BIOS upgrade (no picture)
- Changing BIOS settings (no picture)
- Driver install from safe mode (no picture)
- Fresh driver install using Driver Cleaner software (no picture)
- Different PCI-E slot (no picture)
- Remove all unnecessary power items (no picture)
- Old 7900GS card (no picture)
- New ATI HD 4850 (no picture)
- Vista Low-Res mode boot (no picture)
- Ubuntu (fine, but lo-res)
- Safe mode (fine, but lo-res)
- VGA monitor instead of the Dell DVI (works perfectly)
- Fresh install of Vista on another drive using standard Windows VGA drivers (fine, but lo-res)
- Fresh install of Vista on another drive using standard Nvidia drivers (no picture)
- Changing the BIOS to non-Plug and Play (no picture)
- Another (smaller) DVI monitor (works perfectly)
- Fresh install of XP using standard Nvidia driver (works perfectly)

The motherboard is an Asus P5B. The graphics card is Asus 9800GT.

My tests would suggest that it's Vista not getting on with the 3007WFP for some reason. Indepedently they're fine: the monitor works fine in another operating system (XP); Vista works fine with a different monitor. I'm told that Vista is more fussy about the EDID data coming from the monitor and Powerstrip tells me it's unable to read the EDID data from the monitor. That might be a bad reading though, since nVidia control panel identifies it as a 'Dell 3007WFP' and that name has to come from somewhere.

Any help greatly appreciated.
