Have you tried downloading the zip version of the latest video drivers?
Try performing manual driver installation:
Yes. I already tried that. I tried the drivers supplied with the motherboard, and the latest version which I downloaded.
I also tried the manual installation.
Result is the same with all attempts: Installation fails after 10 to 15 minutes.
The same error message appears in the event log.
I am looking for some more detailed logging. Which hopefully explains the cause of the timeout.
