When I switch on my computer there is no display. When I remove the D plug that connects between the monitor and the the CPU at the CPU I get a no signal message. On reconnecting I lose display. Seems to be the CPU rather than the monitor.

Re: No display on monitor
Hi, sounds like a problem with your base unit, might be a lose graphics card, a stick of memory might need taken out and put back in.
shouldnt be expensive to fix.
as that will give you the fault that you describe with the monitor.
as the base unit aint posting, and the signal aint being recieved,
if you have basic knowledge you should try taking out the graphics card and refitting it, usually does the job :-)
All the best,

If you don't use an identical monitors, then they may not work if your video card can not handle them. The "check video cable" it means the monitor does not get a signal, and it does not mean that the monitor is a problematic monitor. You can test this monitor as a single monitor (and try to connect it using first video port, and then move it to the second video port).
please check on cables connecting the monitor to your tower/cpu. make sure both ends are plugged in tight. check on the monitor power light aswell, if its blinking or not, if the monitor has been more than 5years old too, its possible thats already dead computers have a life time too especially the old models.
This occurs due to the Monitor display cable not connected properly. Please double check the cable from Monitor to the CPU(the main box).
You could also try removing and inserting the cable again.
Please be careful and don't apply excessive pressure as you might break the monitor cable "pins" if inserted wrongly.
This should fix your problem. (Assuming both the CPU and monitor are switched on.)
yes all the connection are intact, in these cases have the cpu check the monitor is not the problem, the monitor is still displaying which means that it is good, have the cpu check or check how many vga adpater is present in the cpu, if you have a built in and a separate card and you plug the monitor to the built it will not work and you need to connect it on the separate expansion card that is install inside your cpu
it simply means that your cpu is not giving back signal to your monitor to process, in fact, it is a cpu problem that is why there is nothing to display in your monitor.
Your cpu froze because of that usb thing. the only way to unfreeze it is to manually reset your hardware in this order.
1. RAM modules. If you can unplug your RAM (memory modules) connected in your motherboard, please do it. Just unplug the modules and then plug it back in. if you have 2 rams, then interchange them when plugging it back. this will force your mobo to refresh its resources.
2. CPU. if you can pull out your cpu chip, then do it. this will refresh your cpu setting in your mobo. (mobo = motherboard)
I am guessing that you see lights on your computer, but no display on your monitor.
Have you tried another monitor? If you have and still no display, try unplugging everything from outside the computer except the monitor and then try again.
If no display, unplug power from computer and open the computer. Remove all expansion cards other than the video card. Disconnect all the cables from all of the drives, then connect power and try again.
I think you need to connect the cpu cable with the monitor to start it.
if still your computer turns on without issue, but your computer screen is showing a No Signal message, it could be due to problems in the CMOS, RAM, VGA card, or the cable that connects your CPU to your monitor.
