Hello there,

Here are my problems :

• When I start-up my PC on Battery, with any 17x.xx drivers from nVidia or Dell, Windows Vista start, then I hear the welcome screen music, the login "ta da" and I still get a black screen...
• If I do the same with the power cable connected, Windows start normally and I get display working.
• When I do the "Diagnostic" or I play to a game that use Ageia PhysX integrated chipset, I get the video card fans running at full speed, which do not seems to be a normal thing.

All those points made me phone the technical support a month ago... My computer was taken to the support center then "repaired". They changed (officially) the motherboard and the graphic card. I got back my computer today, a month after the departure, when I was supposed to get it back after a week. This delay was due to on of the part being unavailable and they was waiting for the resupply.

Now, I tried back on this "fully tested" PC these things and... I got exact same issue... note that the computer was formatted and reinstalled (not completly, I had to reinstall almost all drivers because support center does not).

Have you any idea if this problem is hardware or software (likely Vista) related... Maybe I'll try to install Window XP and see if I get same trouble ?

Regards.
