I have a problem on my computer. few days before the computer runs normally and now this day when I turn it on the monitor displays "no signal" the cpu fan is working fine, the video card fan is also working fine, the casing's fan is also working fine but the monitor's LED just light in blue then after a few sec it turns to orange and displays "no signal" I don't know what happen or what could b the problem. I tried swaping the memory card with my new one but still don't work. I unplug keyboard, Mouse and Harddisk but stil displays no signal. if I remove the memory card from the slot it beeps which means the memory card slot is working fine. Please someone could help me with this problem.

Try this 1

1 ) Once again check your RAM.

If you notice that your CPU fan is running but there is no display in the screen,

then remove the RAM from the slot, clean it and place it back properly or try

another slot.

If you have no idea about RAM, then click on the below hyperlinks "Images".


Removing a RAM

Check your RAM also. Even bad RAM will result in display problem.

If you are having two RAMs then remove it, place only one RAM and check the

display. If you failed to get any display then change the slot. If you still failed to

get the display then try the above procedure with the other RAM.

2) If the problem still exists then remove the Graphic Card and connect your

monitor to the onboard VGA. Now check if you are able to get the display or not.

3) If the problem still exists then try resetting your CMOS settings.

Turn off your PC and remove the power chord --> Open the cabinet -->

Remove the CMOS battery for 15-30 minutes and then put it back properly. Now

plug the power cord back in and switch ON your PC.

Click on the below hyperlink "CMOS Battery" if you don't have any idea about

the CMOS battery

If the problem still exist, click on the below link and follow the instructions in

"Hardware Reset".


Good Luck
