1 long and 2 short beep

Without looking up the actual beep code and just working of the reality that most beep codes are related to RAM or video card errors along with the fact that you just changed your video card, it's safe to say that's the problem. Somehow, I think you realize that, though .

Reseat the card and try clearing your CMOS.

there is a buid in video cards and i also clear the bios but the problems still there

 

Well, attach your monitor to the integrated video card and you'll likely get display. Enter the BIOS (tap Delete upon booting your machine) and configure your default video card to be the one using the AGP slot.

The setting is probably in a subsection of the "Advanced" tab.

 

read the bios beep guide in the guides forum.

i put it already in intregated video i clear the bios, i change the memory but the problem still there

 

Well, then, apparently either your video card is defective or your motherboard greatly disapproves of your selection. Try again.
