Basic system info:
OS: Windows 8 Developer Preview (x64) CPU: Intel Core2 Duo Graphics: Intel integrated/ATI Mobility Radeon HD4330
- After installation everything works fine and it boots to the desktop
- At some point later (seemingly randomly) the screen goes blank (but still on), then turns off, and then on again (but is still blank)
- After this when the computer is restarted a blank screen appears instead of the boot options after the initial boot logo has shown.
So on initial thoughts it appears it may be a graphics issue. I have tried system restore/repair to no avail.
In a nutshell: why do I get a blank screen, and how can I get my display back?
It turns out that after the problem has occurred, putting the computer to sleep and waking it up brings back the display. This technique (putting it to sleep then waking up) also seems to work when the screen is blank after booting, as long as enough time is left that the computer gets past the boot options and to the logon screen before you put it to sleep.
After some more testing (cough reformatting and re-installing) I can confirm that a) after re-installing from the CD all is fine for a while, but b) the problem re-appears after a short peroid.
