screen goes blank while watching online movies (Windows 7)
I have a Dell Inspiron 15R and is loaded with Windows 7 OS.
I usually watch online movies. But after watching the movie for around 10 to 15 minutes, the movie window screen goes blank (white color) but the movie continues uninterrupted as I can hear the audio distinctly.
The observation is that the following things happen in sequence:
- the system hangs for around 3 - 10 seconds
- the entire monitor goes black and refreshes back to the initial screen status
- but the movie screen goes blank (white in color) but audio can be heard.
- if the brightness of the screen was lower before going blank, after the refresh, it restores to the high brightness.
But unfortunately, I have to refresh the URL and start the movie afresh.
I am not much of a games person, but I have observed that sometimes this situation happends for normal computer usage as well - the computer hanging for split seconds, screen going blank and then resuming as normal after the refresh with increased brightness (in case the brightness was low earlier).
Also a warning message appears (don't recollect exact wording), something like - "your display driver had stopped working and now is working normal).
The dispaly adapter I am using is ATI Mobility Radeon HD 5650.
