I have a 5 years old speaker connected to the same socket extension with my desktop PC (i.e. Monitor & PSU). When I turn my speaker on after the PC was booted up, sometimes the monitor will blink for a few seconds and return to operation.
However, there are a few ocassions in which my monitor won't show up. I can still hear my CPU fan running but I noticed that:-
- I couldn't toggle my Num/Caps Lock on my keyboard
- I turned the monitor off and on but it just showing Analog/Digital alternately and finally a blank screen
I've checked the connection is tight but still couldn't figure out the problem. This only happens when I have my PC running and turn on the speaker after that but not the other way round.
In addition, if I've experienced the blackout, sometimes I can't even boot up my PC properly. That is, I turn off everything and switch on my Monitor & PSU only and I can hear the boot up beep as usual but my monitor is showing Analog/Digital alternately again and then total blank. I've to use the hard power button on my PC to shut it down and repeat the boot up sequence a few times again to make it work.
This is very frustating and I'm not sure whether it's the failure of my speaker/PSU/monitor. Any help is appreciated!
