I have just replaced my PC.
As my new baby is a reasonably good system I now use a DVI cable but still using original Monitor.
In an attempt to sell the old beastie I listed it on fleabay and it sold.
To demonstrate it I put it back on the desk and plugged it back into the monitor to allow me to show the buyer. I even used the DVI cable to connect it.
Everything was tickety-boo when the monitor clicked and turned off, thinking it was a restart caused by some updates I waited; The PC kept on chuntering but no picture.
After a restart it now does this after a minute or so, again with the click that a monitor always makes when turning off.
I know the cable is OK as it works fine on new PC, monitor is fine with new PC. OLD PC was fine with no problems for three years until it knew I was selling it.:D
Wondered if moving it on and off the desk onto the floor has disturbed something. Have removed and refitted the graphics card to check it is seated properly to no avail.
Will next try using the onboard graphics to by-pass video card.
Any idea guys?

check all the plugs and cards are seated

try the onboard video

what are you running
video card brand and model
cpu
m/board
ram
power supply
brand
model
wattage

check the listings in the bios for 12v line voltages and cpu temperatures and post them

TBH Dai, as I explained in my last post I am unable at present to find out the details on a PC which does not work.
Thanks for trying but I will just stumble on.

take the side off and look at the psu label

look at the m/board and the model information will be silkscreened on it

it sounds like the psu is the problem

check the ram is seated properly

check all the plugs are secure by removing and replugging them in
