No, not a gripe about the local constabulary.
The other day I was using the Win 10 desktop when the picture went all
multicoloured snowstorm and the PC shutdown.It now won't shut back up
again (if you see what I mean).
I've checked the monitor and that still works fine.The PC was trying to
boot about 3 times and then stopped. The screen was showing the
multicoloured snowstorm or vertical coloured bars before shutting down
due to no input signal. I think the PC was supposed to boot off a CD or
USB drive if appropriate And I think it tried when given the chance and
failed. I've also tried forcing it to boot into safe mode without
success. Without a screen it is very difficult to know what is
happening, and being unable to boot off another device there is no way
to run diagnostics. Now, when it tries to boot, it seems to try one and
beeps, which may mean that the mother board/Bios has a problem - I may
have (just possibly) screwed the BIOS by semi-random key presses during
boot in a vain attempt to get something on the screen.
I'm thinking graphics card failure (I think it has a separate card -
I'll get the screwdriver out tomorrow), but would that cause boot
problems? Is the motherboard toast? Is there any way to force it to boot
from USB without having a screen to see what the boot sequence is?
Removing the HDD might do that.
All suggestions (legal, painless, ideally helpful, and mindful of social
distancing) gratefully received.
