Beeps on startup, no signal to monitor - HP Compaq d530 CMT PC Desktop

Could be a problem with the RAM. You can do a boot-up RAM test with a CD-ROM or USB stick using Memtest
Memtest86 Advanced Memory Diagnostic Tool

This code is an indication that your video card has a problem.
Try removing it and putting it back in. Make sure it's properly seated (that's probably the problem)

One beep means everything posted right
I would start with the video card and pull
it out of socket then reinsert it you could
have a bad card or bad cable or the
mother board cant handle vcard

No Beeps






Short, No power, Bad CPU/MB, Loose Peripherals

If the monitor is showing you a "no signal" message, it's almost certainly working fine. There's no video coming in from the computer, and that's likely where the problem is. Try another monitor first. It's possible yours isn't recognizing the input signal, but it's unlikely. I've only seen that happen twice I can remember. Chances are that another monitor will say "no signal" as well. Either the computer isn't starting up, or the video isn't working.

If you hear all the sounds of a normal startup (usually a single beep when the motherboard finishes power-on tests, hard drive activity shown by the front panel indicator, and finally the Windows startup sound through your speakers), then the video circuitry is bad. If the video is integrated onto the motherboard, you can install a replacement video card in an open expansion slot. If you already have a separate video card you can replace it.

If the computer isn't starting, you need to suspect memory, the motherboard, power supply or processor. You might also have a bad hard drive, optical drive or other device connected which is preventing startup. Begin by unplugging everything except the main parts: memory, processor and fan, power supply and (if used) video card. If the system starts up, you can identify the bad part by reconnecting them one at a time until the problem comes back. If the system still doesn't start with the minimum hardware, part substitution is how you'll figure out which is responsible.

It can be frustrating, but you'll get the thing going. Good luck, and thanks for using Fixya!

that is the problem of cpu not a monitor to confirm disconnect signal cable and power on. monitor will show "no signal check signal cable" it means that monitor is ok and fault lies in cpu .then open the cpu and disconnect ram and listen the beep. contineus beep should be heard then ram is faulty replace it. if no beep heard then motherboard is faulty .

here is a link to all the beep codes this should help you

hope that is ok

If the monitor comes on and displays a message like "no input signal" or something similar, it's working properly but there is nothing coming from the computer. People often think that the computer is working and the monitor is at fault, when in fact the computer isn't starting up.

When you turn on the computer, do you hear the normal sounds of the power supply fan running and the hard drive spinning? Most computers will give a beep when they turn on and the motherboard finishes some startup checks. Do you hear that? Do you ever hear the normal startup sounds that mean Windows is actually running?

If you are convinced the computer is starting and booting into Windows, I would suggest you borrow a known good monitor to use as a test. If it works, that obviously means yours is bad. In most cases there's nothing you can do to repair a monitor yourself beyond checking for loose connections, bent pins in the signal cable plug, or a damaged cable.

If a known good monitor still has no image, the computer is at fault. Either the video card or integrated video isn't working, or the computer isn't actually starting up. In any case, that's where you would need to start looking for the cause.

Hope this helps you along the way to solving the problem. Thanks fo using Fixya!

disconnect signal cable if monitor show massage no signal check signal cable then monitor is ok then open cpu check whether dust is in ram then clean the dust and again fit the ram the problem will be solved if not then disconnect ram listen beep and if contineus beep comes then motherboard is ok if no beep then motherboard is faulty replace it

Get a new Hard Drive and plug it into your USB Port

The beeps are probably BIOS beep error codes. Through a series of long and short beeps the computer communicates computer problems that occur early in the startup processes. It's likely the problem isn't your monitor but something in your computer box itself. If you can tell us what the pattern is we can start diagnosing your problem. We'll also need to know the manufacturers name, the specific model computer you have and what operating system you are running.
