The three beeps is a diagnostic code. The beeps can represent a range of problems depending on which brand of mother board you have and what chipset it has. You can sometimes find the diagnostics related to the beeps online. The first thing to check is to make sure all your cards and ram are properly seated into their respective slots. I suspect your ram. Speaking of which 256 meg sdram is not enough to run todays applications. You should step up your ram to at least 1 gig and if you are running Vista, you'll need 2 gig.

Tip

Computer beeps


If you try to power on your computer and nothing happens but a bunch of beeps there is something you can do. The beeps actually mean something. To make sure you can hear the beeps check in the bios options. If there is an option for a silent boot you won't hear any beeps. If you hear one beep every time your computer starts then you don't have to worry about this.

If you want to check this setting refer to my other tip on how to enter bios and change boot settings.

If you try to boot your computer and nothing shows up on your monitor do these steps first.
1-Check all your cables in the back of the computer.
2-check your power source and power cord to the monitor
3-try another monitor if possible
4-If on a power bar try to turn off the power bar and reset the breaker

If you try to boot your computer and nothing happens and you hear beeps look at this website. The beeps you hear are actually telling you what is wrong. Look at the website by clocking on the link below and click on the computer beep codes link. If you want to scroll down past the link it will show you bios codes to enter the bios in your computer

Toshiba satellitep205d-s7438 won't boot up


You need to be more specific and tell what happens when you plug in the power cord and press the power button. There are a number of reason why a computer will not boot, but if you tell what's going on someone can help you.

Computers don't boot for basically the following reasons, 1) the power supply is bad. That means when you plug it in you don't see any lights, and when you press the power button nothing happens, you hear no fans, no beeps, no blinking lights, no hard drive spinning, no cd drive clicking and nothing appears on the lcd screen.

2) A motherboard issue, usually when this happens you will either see blinking lights or hear beeps. Those blinking lights and beeps are codes that tell the technician what is really going on.

3) Static Buildup - try removing the battery and the power cord then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back in (leave the battery out) and Press the Power Button. If it boots up you had static buildup and can replace the battery, count your blessings and Thank The Lord cuz a dishonest repairman would have told you he had to replace the motherboard for $300

Hi,
Do this, first disconnect your memory into motherboard slot and then power on your PC. if you hear repeated beeping means no memory installed, the motherboard work fine. try to insert again your memory. if your memory are two pcs. insert only one memory and then power on again your PC. (only one by one insert memory for testing so you can trace if one of your memory was defective).
Try this,
Motherboard beeping troubleshooting guide.
(Note: before touching computer parts like motherboard, memory, video card and specially hardisk the very important parts of PC. discharge your static electric into floor ground or the case of your power supply. need also external PC speaker. if no onboard PC speaker ).
No beeps means short circuit, no power, bad processor, open parts or defective parts specially capacitor parts.
See this sample picture of capacitor leakage and defective.

One beep means everything is normal the motherboard work fine.
Two beeps means cmos bios error and defective.
One long beep, one short beep means motherboard need tracing defective parts specially capacitor.
One long beep,two short beeps means videocard problem need tracing of parts CPU and blower fan for working good, also capacitor parts for leakages.
Three long beeps means keyboard error some key press stock up or modules parts defective.
Repeated long beeps means memory not detected, loose of defective
Continuous Hi-Lo beeps means CPU overheat or loose blower fan with heatsink into motherboard chassis.
Try this solution for your motherboard troubleshooting solutions.

Hope this information can help you.
Thanks for using fixya

Hi whisky_zulu,

I see that you have basically done everything possible on the machine still to no avail.

Basing from what you've done still the issue is the same it shows that the motherboard on the machine needs to be replaced.

no beep codes as you mentioned indicates that the motherboard does not respond at all there maybe power but you also mentioned that it also shuts down once turned on for a couple of seconds.

replacing the systems motherboard will be the only solution to this issue.


I hope that this makes it clear regarding your query.

Have a nice day,

PC will not start


This sounds like a memory error, can you define the beeps. There is a thing called a "beep code" on all motherboards, the website for the motherboard defines what the beeps mean. For example: one long beep followed by two short beeps of continous spaced beeps without a break. chris http://www.motherboardsrus.net
