PC shutting down

[Bob Williams]

Les, do you have a friend whose PC you can try with the monitor? Just a thought, if it’s been covered in another post, forget it. Reason I propose this: I have a second-hand Iiyama 24″ ProLite, which had a VGA connection fault. I only found this out when using a KVM switch –     https://tinyurl.com/jmkmg39     – as I had always only connected to the decktop via HDMI.

I think it was Dave who suggested using it on another PC. Connected to SWMBO’s former old HP laptop, which only had VGA, and no joy. Tried a new VGA cable before that, no picture.

Still does not work in VGA, but HDMI works a treat in   1920 x 1280. Probably why it was bought for such a low price! :yahoo:

I never used the KVM switch again. Too many sensible alternatives, which involve less or no cabling. Another product whose time has come and gone. Another lump of outmoded tech in my BitsBoxes…. 😥

When the Thought Police arrive at your door, think -
I'm out.

Assuming that you can remember your login and password, next time rather than the finger/button gymnastics, try switching to a terminal, loggingin and shutdown there. That will confirm if you have something on the desktop blocking.

 

Ctrl-Alt-F3 (I choose F3 because nothing is likely to be using it).

Wait a few seconds then type your username [Enter]

Another few seconds then your password [Enter]

Another few seconds then “sudo shutdown -h now” [Enter] (without quotes)

Another few seconds then your password [Enter].

 

If the computer shuts down, you’ve eliminated the core OS. NB. The few seconds between each step is simply because you are working blind and need to make sure that the previous step has completed.

 

Arch Linux, on a Ryzen 7 1800X, 32 GB, 5 (yes -5) HDs inc 5 SSDs, 4 RPi 3Bs + 1 RPi 4B - one as an NFS server with two more drives, PiHole (shut yours), Plex server, cloud server, and other random Pi stuff. Nice CoolerMaster case, 2 x NV GTX 1070 8GB, and a whopping 32" AOC 1440P monitor.

Just to finish this topic off, I did try a different lead, no change. I then dismantled and examined the PCBs with a magnifier looking for dry joints or any other obvious problems; Nothing and no visible evidence of dodgy capacitors. I am sure I could fault find it if I use the hairdryer and freezer spray, but it would probably take up a lot of time I don’t have. I could try Ed’s suggestion of adding a fan, but think I will just go and buy a new one. I don’t enjoy spending, so may well stick with the TV set for a while, but will definitely give up on this 24″ Acer Monitor.

Les.
