When you first switch the computer on do you get anthying on the screen, or is it blank throughout?

no it doesnt display anything
but it shows that pwer is on

What about monitor light? Does it switch on to show it is getting a signal from the graphics card?

[manish19866]

on gettting the power it says no signal  digital  and then becomes black ie no display,but the HDD led remains at it state without blinking

I would try taking the graphics card out and placing it back in, if it is showing no signal like you say then I think it could be the graphics card. Do you have another one you could try in there if resetting it doesn't work?

You may also want to look at the connections to the graphics card and monitor to make sure they are connected properly.

i had removed the graphics card  and then again placed but it doesnt work
 hav checked the connection it seems ok

and i dont hav another to check .

wht to be done next?

Do you have onboard graphics on that motherboard? Do you have vga aswell as hdmi on the back of your graphics card? If so I would try connecting it to the other slot, like hdmi to vga.

i dont see any fan in my graphics card  its a 128 mb graphics card

for the vga port i dont hav the cord for it

I would look at it been the card first and I suggest you borrow one of a friend to test it?

how coul i boot when i dont hav the display and dont know what is happening  with the system  when no displey is dere


what could be the problem with  HDD led which displays in continuous manner ie . doesnt blink at all

I was testing one thing at a time for you before going on to the next thing, but since you cannot get hold of these things I'm not sure if I can help you anymore. Without a display how do you expect to be able to diagnose certain problems? Say like if you disconnected the hard drive the display would show on screen that there was a harddrive error..etc. However, you dont have a dispay so it lead me to believe it was the graphics card or monitor problem maybe.
