1 Answer

No display on monitor

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, John

Dear sir, my motherboard is amd athlon 64 socket 939.when i on the system then system is running but processor fan is not rotating.Finally after 25-30 minutes it automatically turned of and displays cpu...

It sounds like the cpu's temperature is raising over the safety level set in the bios so it switches off and displays the error!
to solve this either:

Your cpu cooler fan needs replacing


Your current cooler fan isn't connected to the correct socket on your board (check you're user manual, usually a .pdf you can download from manufacturers site)


Just try connecting your current cooler fan to the cpu and see if it turns on at all. If not make sure you replace it with one that is compatible with your system that can fit in your case

If the temperature has raised to a significant level the thermal paste could probably use replacing also, so get some thermal paste remover and thermal paste, and read in your motherboard user manual how to replace the cpu heat sink safely.

Pc starts but black screen

Bad video card, bad hard drive, bios battery. If you have a screen but only a blinking cursor on it, likely a bad hard disk drive, meaning all your data and files are now gone, also your os is likely inaccessible. If you can heart it boot up like normal through speakers then video card or monitor, more likely the monitor's power supply is bad, find another monitor (size not important, just the display connector) and connect it to your PC with the power off. If it works then it's the monitor that is bad, purchase a new monitor, if another known working monitor doesn't solve the screen issue, it's probably your video card. A new card is cheap and you should be able to install a new one and have basic display until you install the drivers.

I had removed my pc to another room but after installed and checked all the cables connection the cpu was on but monitor and keyboard was not working

You might have bounced the video card out of the motherboard. Open the case on the computer (with power off) and push down on all the cards and make sure they're seated in the motherboard then try starting the computer again.

Make sure you go into the bios settings of your motherboard and shut off the on board VGA. You will need to plug the monitor into the onboard VGA adaptor before proceeding to use the secondary adaptor.
