Hello.

I upgraded my videocard to HD7770 recently, and found this annoying hangs. Just
like described: "after some time of work screen goes dark, than blinks and than
hangs (picture stands still with no changes and no reaction on keyboard or
mouse, numlock isn't working)." I can add that the monitor draws "no signal"
message, than finds that signal, makes autoconfig and nothing happens than.

The most of such a hangs happened when I played "Heroes of The Storm". The last
3-4 times I tried to enter game system freezed. But as it seems for me, the
training games are works fine. Maybe it not relevant information, but just for
case.
The system becomes unusable, acpid don't respond on power button, the only way
out of it is reset button.

And one time right now system *almost* died when I clicked at link in firefox.
Almost. All looks the same: screen goes dark, than lit again, but I
successfully switched to first virtual terminal with C-M-F1 and see there
something like "failed to allocate virtual address for buffer" and some more
lines. But I was stupid and the next thing I done was C-M-F7. System died.
