Hello bleeping Computer..

I have a problem with my old desktop..

I am studying in other region in my country..then came back home for holiday..

Then I want to set up my old desktop for my brothers..

I try to turned on the desktop..nothing appear on the monitor..What comes in my mind is may be the monitor got problem..later I tried to turned on the cpu with another monitor that well functioning before I tried with the cpu..

Again there is nothing on the screen too.. the cpu seems running ok..I open the casing..all fans working..the lights inside..dvd rom is ok too when I eject it..however the led on the keybord and mouse did not appear..

So I need help..what should I do? The cpu is doing very fine when the last time I use it..

Hi ezooone,

If you have tried 2 monitors and the condition remains the same you can rule out the monitor as the problem.

If you have a video card on the motherboard - try taking this out. Clean the contacts with a pencil eraser and put the card back to try again.

If you have on-board video too ( 2 VGA connections at the back of the box ) take the video card out and try the on-board video.

Also check the inside of the case for dust. This can cause various problems. If there is a buildup then blow this away or use a very soft brush. Pay particular attention to underneath the motherboard.

==============
EDIT:
Are you getting any POST beeps?
If so - what sequence?

Hi ezooone,

--> Does it have power..? Check the power cord that it is connected completely
Note* Some monitors (such as Samsung) may have an additional power switch on the back as well as the the front..if there is a power switch on the back of your monitor make sure that it is turned on and then press the power button on the front of the monitor.

--> If you are using a DVI cable press the Source/menu button on your monitor and make sure that the source is set correctly. (DVI, VGA)

--> What happens when you unplug the video cable from the back of your computer..?

The port connector for VGA seems to be missing one female-type screw.

Usually that screw not make that problem.
If you dont use Serial Port right at top of your VGA Port you could open one screw on it and put it on your VGA Port that missing screw. To open that screw you just need to spin it with pliers (to right or left).

You situation is called as No POST. you could read this article and try it.

Done all the steps..

Trying the power cycle and disconnect the hard disk/ram/dvd rom/mouse/keyboard/cpu..and turned on

The result is still the same.. :(

I think the problem is the motherboard..what do you think?

When switching on the monitor together with the tower, does monitor displays all black and power button orange? Does cpu tower boots by just looking at the keyboard(numlock usually lits up steady) or by getting a respond when pressing numlock?

Did you try pressing "numlock" about a minute after pressing power button? If there is a response from numlock pressing once then led light turns green, then there is booting activity w/out display.
