HOPE THIS CAN HELP YOU.

This is likely a result of the computer not recognizing the monitor. During the POST test during startup,the computer will check for a video output. It can range from the video card failing to just not having the monitor plugged in. I would check you connections, perhaps try a different monitor, even a television that has either HDMI, DVI, or VGA input. If that does not fix it, it is likely your graphics card or on board graphics from the motherboard. Is there anything new since the last time the computer worked? How old is your PC?

press f8 and keep pressing untill menu appears tjen highlight on enable vga mode and press enter your problem will be solved if you want to see high resolution then insert an AGP card into an AGP slot then you can see high resolution use 8X AGP card for better result

Try pulling out your video card and your memory chips, then re-seat them and restart. If the computer doesn't start, take either the memory or the video card out, then try to restart.Listen to the beep as it resarts, and if there is a change in the beep code, you have found your faulty part.

Switching DDR cards solved the problem. I was getting long beeps every 2 seconds. No short beeps. Just one long beep every 2 seconds. Thanks Josh Whitehead.

take the moniter to a known good pc and see if it work if moniter works correctly it is your video card if not you need a new moniter

5 beeps is processor(cpu) failure

are they long? short?

Try another processor on the computer and see if it works.
do you get the same beeps if you place the old card back in?

Whats the brand and model of the motherboard?

its reads between the cpu and memory and also between the expansion slots, and possibly on top of a heatsink

let me know


Thanks,

This might be problem with your RAM. Remove the RAM and connect it to another memory slot or try changing RAM with new one.
Remove your PCI card and try now...

Check the inverter board.

What is the beep pattern? beeeeeeeep, beep,beep beeeeeep etc. also what BIOS do you have?
