If you don't ever see anything on the screen it is certain to be a hardware fault, which is probably why you posted it in this section.

Can range from PSU failure to dust build up inside. Just wondered if it was still in warranty, if so that might be the best way to go.

Always pop back and let us know the outcome - thanks

This crude PSU check might be of interest:

You need to remove all the PSU's connectors first though.

Sounds like the PSU has failed or is failing.

"Trendsonic Casing with standard PSU"

If the PSU came with bundled with the case, it's most likely a low end unit. I just did a search for Trendsonic power supplies & had a look at some of the specs; they do NOT look good. I would switch it out. If you're in the US, I recommend this Corsair 430W for $25 (after promo code & rebate):

Or you can get the 600W for just $10 more:

Oh dear. Something quick and easy to try:

Remove RAM and clean its edge connectors with a pencil eraser, then pop the sticks in and out a few times to clean any oxide off the sockets. You could do the same with any plug in cards. Both SATA power and signal connectors have been know to suffer from poor connections (that look fine on inspection). While you are in there check the seating of any connectors that you haven't already fitted as part of the PSU change.

Try running with each RAM stick on its own in first position just to see if just one is playing up.

CPU (or it's seating) and motherboard are still possibilities but do the above simple checks first.

Always pop back and let us know the outcome - thanks

Make sure monitor light is on (at least amber) or it might be turned off or power cord may not be fully seated.

Look over monitor cord (signal) to make sure it is fully seated at both ends and there is no damage to the cord or connectors.

If the machine was moved recently, check all internal an external connectors to make sure nothing is loose (power unplugged first).
If the machine was just put back into service or monitor or other components were moved or unplugged, make sure all is connected correctly (Some machines have more than one monitor connector, especially one on motherboard and one or more on a video card, make sure you are choosing the correct one).

Use a can of compressed air to blow out dust from internal areas, especially heat sinks, fans, and vent openings. Do not allow the compressed air to force fans to spin faster than is normal for them (use short bursts or hold them from turning).

You have to be a little bit crazy to keep you from going insane.
