Title: No Signal To Monitor
Post by: GillE on April 01, 2019, 23:20
My monitor told me today that it is not receiving a signal.  I unplugged the cable from the video card and connected it into a VGA socket which goes directly into the motherboard.  Still no signal.  I then tried an older monitor which I knew to be serviceable and found it didn't receive a signal either.  Finally, I connected my original monitor to an older PC and found it worked perfectly well.

A week or so ago I installed a new SSD which seems to have been working fine.

Can anyone help me, please?

If it's been working for a week, then it would seem doubtful that it's anything to do with the SSD, unless somehow you disturbed the graphics card while installing the new drive?  It might be worth popping the case off and checking that the graphics card is seated and connected securely.

It's a bit odd that you didn't get a signal from the GFX or the onboard card !
Have all your tests used the same cable from pc to monitor ?
If they did then you almost certainly dislodged something when installing the ssd...tho' i'm not sure what would account for neither working. possibly power supply to mobo?
Is the pc posting / firing up normally ?

My tests have used different video cables.  I donít see how I could have dislodged any cards - theyíre miles away from the SSD.  The machine appears to be booting up ok but without a video output itís difficult to tell.

I wonder if your onboard graphics would actually work if you still have the graphics card installed, as when the PC boots it would default to the graphics card.  Maybe remove the graphics card and connect the monitor to the onboard graphics and see what happens then?

Tried that, Simon.  The problem persists although this time I did get some warning beeps on boot up.

OK, so what happens if you reseat the graphics card and try that again?  I have to admit, this is all guesswork as I can't think what else the problem could be, but it does sound strange that both your onboard graphics and your graphics card appear to be affected.

By the way, the additional beeps are probably just to tell you that there's no graphics card installed.  With any luck, by removing and replacing the graphics card, this may force it to reinstall and that may possibly help.

I wouldn't knock anyone for their choice of diet.  It all comes down to what each individual's conscience can stomach.

Literally!
