Black screen/monitor goes to sleep minutes after powering on
A matter of minutes or even seconds after powering on, the screen goes black. There is a "no signal detected" message is displayed. That is to say, the monitor has gone in to sleep mode. Sometimes a slightly louder whirring noise can also be heard for about a second or two before the monitor goes to sleep. No idea exactly which component is making the noise. From what I can gather, everything else seems to function fine after the monitor goes to sleep.
This is not a Windows problem as it has also occurred whilst in BIOS.
I first started getting the problem a couple of weeks ago. There were no major recent hardware changes other than the replacement of some frustrating Microsoft wireless keyboard with a generic PS/2 keyboard -- which I have reliably used in the past with no problems whatsoever.
