It's a Samsung all in one PC. I did all the possible troubleshooting.
1. Checked screen in HDMI mode working continuously with out any black screen.
2. Two RAM slots checked by swapping the RAMS, only with single RAM, and all possible variations. Tried with new RAM as well but no change still screen goes black.
3. Disconnected all the motherboard connections and reconnected and powered on still same black screen.
4. It worked for 30 mins before upgrading graphics, bios and chipset drivers. After upgrading it went black. So I installed new operating system erasing all previous data. I formatted with NTFS slow format. And later installed fresh windows 7 operating system.
Weird thing is screen doesn't go black while installing operating system. After installation it will login to windows and goes black after few seconds. Again same thing "BLACK SCREEN" but can hear login and shutdown sounds.
5. I couldn't able to do something with bios settings as the screen goes black.
Could you please suggest any other trials that I can implement to reset bios and to uninstall graphic drivers and chipset drivers. Is it possible in safe mode? I don't think even it not gonna work but want to try it. Or IS THERE ANY OTHER BETTER SUGGESTION FROM YOU. Thanks to one who can come up with new suggestions other than those I already did.
