check your manual for the location of the jumper on your motherboard or you can try removing the cmos battery for a few hours, then put it back in

Is the monitor light on?  Make sure all the cables are attached, make sure nothing came loose.

check to see if the video cable came loose or is damaged.  If these are both o.k., check to see if the video card was bumped (cable bumped and card dislogdged).

should it have code beeps if there was a problem with the video card? Could it be the Mother Board?

Since you are not hearing anything, i'd suspect a power supply problem first.  You may have a motherboard issue, but that's rare on modern systems.  Since you're not seeing any video whatsoever, though - the video card itself may have failed.  That would explain why you see lights, but nothing else.  ... so... i'd be looking closer at the video card.

I hear the Hard Drive Reading, could it be the Video Card even though there is no  beed code?

It can be anything - here is what i would do in your case :
-disconnect as much as you can, and boot with the minimum :
mobo + cpu + 1 ram stick, 1 harddisk, video card, keyb and mouse. --> if still no image, the bad guy is one of them; try with other ram, or another video card.
This leaves you (if still no screen) with mobo, or cpu as bad guys
The prime suspect however is still the power supply, so, if possible , test with another one too

try resetting your cmos by following your manual to reset the cmos by using the jumper on your mobo
try removing the battery for awhile or replace the cmos battery

Resetting the CMOS resolved the Problem Friair Tuk, then I had to format the hard drive because of corrupted boot file. thank you very much.

FriarTukCommented:
that's great!  i had that problem before too, although my drive was ok.

fyi, the corrupted boot file might have been fixed by doing a Repair on the o/s, hopefully you didn't lose too much.
