That's odd.

I have the 7750G-6662 series and it's working fine for me..

Did you try updating all your drivers too?

Hmm..that's odd. Not sure man to be honest.

Call up Acer support, this sounds like a level 2 issue.

I only mention this because I just ran into it (black screen on startup - can hear Windows running):

Check your Disply settings and see if you have 2 displays listed. On the laptop I was working on it had an HDTV listed as the primary display. The owner has no clue how that setting would have changed (unintentional).

I made the laptop display default and the issue went away. It is worth a look.

The version of Intel driver can also cause it. Check leshcat site, I believe some people have to use the 2559 version.
