Computer Beeping - - Troubleshooting Computer Startup Problems

If you're greeted by one or more beeps and a blank screen when you switch on your computer

, don't panic: you may well be able to fix the problem yourself. The beeps you're hearing aren't just random noises, they are actually a code which tells you what may be wrong. The code itself is dependent on the bios (basic input/output system) chip on your computer's motherboard; for example if your computer has a bios chip made by Award, then one long beep would indicate a problem with the memory but one long beep followed by two or three short ones would mean a problem with your computer's graphics hardware.

However, rather than trying to decode these noises, there are two things you can check which will very often cure the problem without you having to take your computer to a technician for an expensive repair. More often than not, the beeps will indicate a problem with the memory or graphics card.

Checking the Memory

A loose memory card or one with dirty contacts is often a reason your computer won't start. Fortunately, it's easy to fix. First, unplug your computer from the mains - this is very important if you are to avoid permanent damage to the memory. Static electricity can damage the memory, therefore, either wear an anti-static wrist strap, or ground yourself by touching the metal part of the computer case. Then undo the two screws on the back of the case (the ones on the right hand side if the computer is facing away from you), to release the side panel. Lay the computer down on a flat surface. You will be able to see the computer's motherboard which will have various cables plugged into it. You should now be able to see your computer's memory chips. Generally, you will have two or four slots about 5 inches long, with a clip on each end. Any or all of these slots may be occupied with memory cards. Simply unclip the card(s), and holding them by the edges, gently clean the gold contacts with a clean dry, lint-free cloth. Re-insert them firmly (they only go in one way, make sure the notch on the bottom lines up), and ensure the clips are properly engaged. Plug the computer in and try to start it again. If your problem persists, then try the next option.

Checking the Graphics Card

If your computer has graphics built in to the motherboard, then this won't apply to you. If however, you have an add-in card, then this may cure your problem. Again with the computer unplugged, remove the lead from the computer which runs to your monitor. You will probably have to undo one screw in order to remove the graphics card, and also possibly undo a clip on the opposite end from the monitor connection, where the card plugs into the motherboard. Take the card out and carefully clean the metal contacts with a dry cloth. Re-insert the card firmly into the motherboard, and put the screw back in.

There is no guarantee these steps will cure your problem, but many times one of these simple solutions can save you a lot of frustration and expense.
