Three beeps that repeat after a pause and occur when you power on your computer indicate a problem with the system memory. Three beeps that play and then stop as the computer starts successfully mean that the BIOS was restored.

the number of beeps will tell you what the problem is the beeps are an error code here are the code list for your computer

Beep Code Description No Beeps No Power, Loose Card, or Short. 1 Short Beep Normal POST, computer is ok. 2 Short Beep POST error, review screen for error code. Continuous Beep No Power, Loose Card, or Short. Repeating Short Beep No Power, Loose Card, or Short. One Long and one Short Beep Motherboard issue. One Long and Two Short Beeps Video (Mono/CGA Display Circuitry) issue. One Long and Three Short Beeps. Video (EGA) Display Circuitry. Three Long Beeps Keyboard or Keyboard card error. One Beep, Blank or Incorrect Display Video Display Circuitry.

Usually three beeps indicate a problem with the RAM, reseat the RAM and then try to boot up with disk warrior. Hope this hels.

Dear,
Did this situation come with any beep sound. Because, most of the time, in this situation; the computer beeps. Here are some codes. Check if any of these condition apply to your system.

No Beeps Short, No power, Bad CPU/MB, Loose Peripherals
One Beep Everything is normal and Computer POSTed fine
Two Beeps POST/CMOS Error
One Long Beep, One Short Beep Motherboard Problem
One Long Beep, Two Short Beeps Video Problem
One Long Beep, Three Short Beeps Video Problem
Three Long Beeps Keyboard Error
Repeated Long Beeps Memory Error
Continuous Hi-Lo Beeps CPU Overheating

best of luck!

replace the ram

One beep during startup is "good", but THREE is not good.

Three beeps means a hardware fault -- probably that the video-adapter on your computer has failed.

Connect the monitor to another desktop/laptop, to confirm that it still works.

Turn the computer off, and disconnect the power-cord.
Remove all the RAM, and then re-insert just one stick.
Reconnect the power, and try to boot.
If you still get THREE beeps, turn it off.
Disconnect the power-cord, and reinsert the remaining RAM sticks.

If you still have the problem, then it's time to replace the video-card on your computer. Take the computer to a computer-store, so that they can sell you a video-card that will be compatible with your motherboard.
Hopefully, if you buy the video-card from them, they will install it for a modest fee -- ask them.

sounds like memory problem but to be sure contact the manufacture and find out what the 3 beeps mean.

If they're occurring right as you turn the computer on, it's your Power On Self Test (aka POST) letting you know. Since I can't be more specific, here's a synopsis of POST beeps:

One single beep followed by three, four, or five beeps -- System-board problems, possibly with DMA, CMOS setup chip, timer, or system bus. The computer usually won't boot when this is the problem.

Two beeps -- The POST numeric code is displayed on the monitor, usually nothing to be concerned about, but you might google the code on another computer and see what you get.

Two beeps followed be three, four, or five beeps -- First 64K of RAM has errors. Solution is to replace RAM.

Three beeps followed by three, four, or five beeps -- Keyboard controller failed or video controller failed. Either you won't be able to see or type with this error.

Four beeps followed by three, four, or five beeps -- Problem with serial or parallel ports, system timer, or time of day. Check your BIOS settings (usually F2 at start up) to make sure everything is correct.

Continuous beeps - problem with power supply. Probably won't do much with this error. At the very best, your computer will boot and run very, very slowly.

Hope that helped.

If your computer is beeping at you, 9 times out of 10 its going to be an issue with the memory or video. (more often the memory) Try re-seating both. If your still hearing the beep fest, below is a list of the most common beeps and what they refer to. This will help you to find out what needs replacing.

Long beep followed by 3 sequential short beeps. This issue is linked to your Graphic card configurations
