No signal from computer

[JJT]

Got a problem with our office desktop. Old man said the computer just froze last night so he just held the button down til it turned off. Now when you turn it on it starts up but there is no signal to either of the two monitors. Just using integrated graphics, no graphics card. Have tried taking out the battery on the mother board. Tried taking out the ram and reseating it. It has a ssd hd. Was going to try swapping the ram with my computer but it uses ddr4 and office computer is ddr3. Could it be faulty ram? Is there anything else to try?

Thanks for any advice,

Joe

Try one stick of ram only, and unplugging everything bar the monitors, including the keyboard and mouse.

Have you looked in Device manager for problems?

Only has one stick of ram. Haven't tried unplugging everything else.

Remove the RAM and see if you get any error beeps - should be something along the lines of a semi continuous tone

Power supply could be at fault?

Is the hard disk light flashing when it starts?

Put 'Computer not starting checklist' in to Google, there are a few threads will come up for you to look at.

Tried starting it with no ram in, fans start and it whirrs a for a couple of seconds then shuts down and tries again, repeatedly. No error beeps though

open BIOS and start in safe mode ?

There is no signal to the monitor, at any point, when you turn it on.

Could be CPU or Motherboard failure or worse the SSD if not backed up.

Have you a copy of Windows on a disc? and have you a disc player in the computer, that would be my first thing to try see if it will start from that. Then it depends how the BIOS is set as to if it will try to boot up other than from the SSD.

Stating the obvious but have you checked the monitor supply plug/fuse?

oh ! not much you can do then

sounds like it needs to go to a repair shop

 

[Netherfield]

Whatever, let us know how you get on, I hate mysteries like that.

I have 2 monitors, both have no signal. They are turn on, but breifly show "no signal" then go blank.

From that chap in the pub:
1)Remove power cable and hold down the button that turned it off for 60 secs.
2)Reconnect and restart.
and/or locate video card and ensure securely mounted.
3) Take Clives advice.
