Vista Shuts after 15min, Then Is Nothing!

Hello,

I hope you can help expanded. I am in despair and do not know anymore.

Hardware:

AMD 64X2 3800 +
ASUS M2R32-MVP
3GB DDR2 Ram
2x X1950pro


I have now install Vista, also has everything went great extent.
After installation start the computer restarts and settled for 20-30min time.
If I work as the wanted open space, it lasted about 3-5min. I thought that the lack of drivers could Asus Cd-so pure.
After about 10 minutes I had no desire more, because the CD still had not opened.
The mouse pointer can move but superfluous? But launch bar or the same open-Nothing!

I hope someone knows the answer.

Hardware or software conflict? Check for the same

It could also be a good thing, the vista was installed sloppy ...what is still on the disk? It was previously formatted?

If I knew.I've now installed XP again and wanted information and solutions to my problem collecting. In Vista, I get so, as described, nothing out.
I thought that the error was possibly known.

But many thanks for the tip. Let's see whether more solution proposals. Then I start a new trial.

Edit: Well, I've installed as ever. Operating purely from CD, format / fast (Maybe this is a problem?), Install the new operating system
