black screen bug

Hi,
while playing a metro app, my screen turned black.
Now, even after reboot, i cant see a thing. Display works until the win8 boot screen disappers.

any ideas ?

already have same problem, and traditionally reinstall win 8 , that's it :|

My notebook got two graphiccards (ati, intel). Out of the box only the Intel chipset is working. Windows autoupdate is updating the ati driver, which causes the error.

Preventing windows from downloading the update and disabling the ati-chip in your device manager will fix the problem.

This happens to me randomly like once every 10 boots or so. I found a curious 'fix' for this problem, at least it helps get into my desktop, maybe it will work for you:

When you see the black screen on boot, press this sequence of key combos:

1. Alt+F4
2. Enter
3. Windows+D

Voila! You're in your desktop.

I suspect the black screen is the metro UI not appearing properly or something like that, idk but this works for me every time.

Hope this helps!
