PC turns on but no signal

Right. Excuse my lack of technical lingo. I'm good with computers but don't know the correct lingo.

So my PC turns on. Fan spins and the led lights all turn on but I get no signal.

I have checked the graphics card and the fans not spinning so I removed it and plugged the VGA into the onboard. FYI I tried 3 monitors first.

Still nothing. I discounted all 32gb of ram. 4 x8gb Put them all back 1 by 1 checking if any where the cause and still nothing.

I removed the battery and still nothing. I replaced the battery and still nothing.

I got some canned air and cleaned it all. Nothing.

At one point I had no battery inserted and 1 ram stick and turned it on. And it game me signal??

Yes... so I turned it off. Added the ram. The battery and I'm back to square one.

I then tried getting it back on by removing what was added after it turned on but nothing..

I have tried a conversation of battery in and out different amounts of ram. Graphics card back in and out. Discounting cable and re connecting. Holding button down when turning on and off.

I'm lost please help

could be a bad monitor cable if you have used the same cable for all monitors.

Unfortunately not. Each monitor has its own lead. One of which HDMI

possibly bad cmos battery as the only time its worked is with battery out?

If only that simple. Tried 3 batteries now :(

Back to basics

remove graphics card and use on board graphics vga

1 stick of RAM

disconnect all hard drives and optical drives

no USB devices plugged in

will it boot to BIOS?

Is it worth investigating the PSU. It may not be delivering sufficient voltage

  Darren Claringbold 11:55 15 Nov 2016

Thank for the reply.
So I have tired all these steps except testing the psu as I don't know how.

Last night I removed the cmos battery and left it out over night. This morning I popped it back in and the computer fired up giving me the option to run last known good configurations.

I hit yes and it loaded. Once it got the the login screen I powered it off. Reconnected everything and put it back on and I'm back to square one?

Now I'm really lost

As suggested it does sound like power supply.
