My pc just beeps every 2 to 3 sec no vedio - Computers & Internet

This is a motherboard issue or video graphics card problem, disconnect video card if possible, if beeping stops you have found the problem. If no change! sub out the ram one stick at a time and test, repeat until every piece has been tested. If none of these work! the motherboard is suspect.

Either your video card is bad or you might have some bad memory. Does the video ever post anything on the screen when you press the power button to start the computer?

It really sounds like a memory problem.
Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.
