Computer has three short beeps as it starts
Question:

Computer has three short beeps as it starts.
Cause:

Computer RAM (memory) related issue.
Answer:

Warning: Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards. Information about ESD and proper grounding techniques are found on our ESD help page.

Remove added memory

If you've recently added or tried to add additional memory to the computer and have started getting these beeps. Remove all new memory you've added to the computer. If the computer works fine after removing the new memory you're encountering either an incompatibility or defective new memory.

Additional information about determining the type of memory to use in a memory upgrade can be found on document CH000910.

Open computer and reseat memory

Sometimes when the computer is moved and/or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the computer.

Swap memory location

If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.

If you have more than one stick of memory try removing all but one stick of memory and boot the computer. If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory.

Try another computers memory

If you have access to another computer that uses the same type of memory try using its known good memory in your computer.

If another computers memory works you know that you have bad memory. If another computers memory does not work and it is compatible with your computer unfortunately your motherboard and/or the slots on the motherboard are defective causing it to be unable to properly read the memory, which means the motherboard will have to be replaced.

Replace memory

If you've determined or believe that the memory in y our computer is bad we suggest that you replace it.

Additional information about determining the type of memory to use in a memory upgrade can be found on document CH000910.

Information about installing and adding new hardware including memory can be found on document CHADD. Read Full...

Hardware Refresh

Hardware Refresh

Here's a cool way to save yourself some time. If you have any kind of external (non USB) device (like a scanner, tape backup, external zip drive, etc), they probably need to be powered on before you boot up your computer. If not, the computer doesn't recognize them and you need to turn them on and re-boot. Or do you?

For example, let's say you forgot to turn on your scanner. Now, normally you would have to turn it on and re-boot the computer. Wait - here's how to get around it.

1. Right-click My Computer and select Properties from the resulting menu.

2. Click the Device Manager tab and then the Computer item at the top. Towards the bottom of that screen, you'll see a "refresh" button. Click that.

Windows will now "refresh" it's hardware profile! Once it's done (it shouldn't take too long at all) you'll find your scanner is now part of the hardware profile and you can now use it, no re-booting required!

This will (should) work for any device that's attached to your computer and you forgot to turn on. It seems like I need to hit the refresh button twice on some computers to get this to work. Go figure.

Please note - if you forgot to attach a device to your computer, it's best to attach devices to the computer ONLY when it's off (Unless is a USB device).

Printer Sharing

If the computers are networked together, enable printer sharing on the computer with the printer. This is done under the Network icon in the Control Panel.

Then, install the networked printer you created above on the second computer. You do this from the Printers folder in My Computer (XP users, head to the Control Panel). Just click "install Printer" and when asked, tell it you're installing a network printer. There's a handy little wizard to guide you through the process (it's actually very easy). That should get you printing.

The only potential problem I can see is if the printer is not able to be used on a network. Most can be, but there are some that will refuse to run.

OK, but what if the computers aren't networked together?

If they're not networked, you still have an option. Most computer stores sell a switch box device that can be used to connect a single printer to several computers. Although this doesn't work everytime (some printers are funny about switchboxes), most of the time it does the trick. You should be able to get these switch boxes for under $30.00.

A word of caution - you may want to check your printer documentation to make sure that the switch box is safe for the printer in question. I've never really seen a problem with using a switchbox, but it never hurts to check.

Clean Computers

When it comes to our computers, all we tend to think about is the stuff we see on the screen - the software. Most of tend to neglect the computer itself.

What can you do with your computer to make it run longer? Keep it clean.

I can't tell you the number of computers I've opened that have been clogged with dust. In fact, I've seen computers fail and have intermediate problems due to excessive dust build up. In addition, a lot of dust in your computer can cause it to run hotter than it should, shortening its life.

So, what can you do?

I recommend that you open your computer's case (unplug it first) about once every 6 months or so and blow it out with that canned air stuff (you can get it at any office supply store). Of course, be careful not to disconnect or damage anything. Make sure you blow out the power supply (DO NOT open up the power supply unit) and the CPU fan too. Since all this dusting can make a mess, you may want to do it outside.

Here's a shot of one of my dirty old PCs. This one uses a Pentium III processor, so its CPU fan is vertical in orientation. Your CPU fan may be flat on the board.

Also, make sure you keep your can of compressed air upright. The propellant inside those things tends to come out when the can is inverted or at an angle, so be careful.

Oh, if you can get some kind of good "mini-vacuum" that would be OK too. In fact, some would argue vacuums are better because compressed air can force dust deeper into the cracks and crevices of your computer.

That said, I still like canned air better for a several reasons.

1. I've yet to find a little vacuum that was any good. They all seem to leave a ton of dirt behind on the boards. In my opinion, if you can't get all the dirt off, what's the point?

2. In addition, there are a lot of places that even small attachments just can't get to. Again, what's the point of cleaning if you can't get it all?

3. I've been cleaning computers since before DOS, and have yet to actually see a problem with using canned air. In my opinion, compressed air simply removes the most dust. So, I'll stick to my little cans, you can still vacuum if you like :-)

Finally, no matter how tempting it is, washing your computer with the help of a garden hose is always a bad idea :-)

When U LOSE U R MOUSE

Yes, I hear that cry daily... You're typing along, life is good, then you need to click on something and you can't find your mouse. Despite moving that little critter all over your desk, your eye can't seem to locate the pointer. Ugh!

Well, here's a quick solution for you Windows XP users:

Click on Start, select Control Panel, click on "Printers and Other Hardware," and choose Mouse. In the resulting window, click on the Pointer Options tab.

In the Visibility section, I would recommend un-checking "Hide pointer while typing" so your mouse cursor doesn't disappear that often. Then check "Show location of pointer when I press the CTRL key." This will activate a bulls eye target to appear around the mouse cursor when you press the Ctrl key.

(Your mouse control panel may look different and have fewer features, so don't be surprised if it is not the same as what you see here.)

And don't worry, it won't interfere with keyboard shortcuts using the Ctrl key. Once you've made your selections, click Apply and then OK and you'll have a mouse that doesn't scurry away quite as much!
