I am having this issue all on a sudden in my 4 year old PC. After I start my system, it boots as usual, monitor turns on after single beep and proceeds to load the OS. However it turns off after 1 minute or so, irrespective of what the current state of the system is (starting OS, prompting password, even in BIOS). Even the power LED in the monitor turns off i.e. it doesn't show running (green) or idle (orange), but turns off as if the monitor is not getting power. This happens every time I start the system.
I tried disconnecting the components (graphics card, RAM etc) and reconnecting them, but it didn't work. What can be the source of this problem? Is it the monitor or the graphics card? Or something else?
Edit: One strange observation - after the monitor turns off, if I shut down the system (by long pressing the power button in cabinet) and wait for a while, the monitor power LED turns on to report idle (orange).
