1 long, 1 short beep : System board problem
1 long, 2 short beeps: Display adapter problem (MDA, CGA)
1 long, 3 short beeps: Enhanced Graphics Adapter (EGA)
3 long beeps : keyboard card


The beeps are post during post the very first work is done by the RAM , all the memory in the RAM is first transferred to the hard disk,and remains active untill turned off.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


Make sure that your RAM modules and Cmos battery are securely seated

on some motherboards Cmos batteries are soldered in.


Test all power and data leads that attach from Motherboard to your Hard Drive IDE SATA

Make sure they have a secure dust free connections if its a flat 40 pin ide it will be the first to fail


Check the graphics card is seated properly with no dust in the socket you might have to remove it to check for dust reinstall it.


Restart your computer the found new hardware wizard should activate

A computer needs power and data to travel through every working device and to its continue its cycle and to have and end to function.

Make sure all leads that are attached to your drives dvd\cd and floppy drive have secure Make sure the connections and are not faulty or just replace them they could be faulty

A computer needs all electric current and computer data to travel to and through every working device and have an end to work properly so any faulty leads will end up with a computer error.

Also check the Keyboard for secure dust free connection ps2 and or usb.

Click start control panel administrative tools computer management device manager scroll through devices if you see a yellow Question / Exclamation ? ! or a Red X a new driver will need to be installed / updated.

Right click to update driver.

If you computer came with a motherboard disk the drivers could be on it.

Rather doing a driver hunt which can take hours


http://download.cnet.com/slimdrivers-free/3000-18513_4-75279940.html

Windows XP/Vista/7/8


it might take some time being a freeware driver solution

note: it will find all of your outdated drivers

This is a free driver solutions.


This will automatically search for and find the correct driver

you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.


Hope this helps.

SOURCE: computer wont boot hear one beep from motherboard over and over

If your power supply is bad, there is typically a much cheaper way to fix it rather than purchasing a new one.

If you know a little about electronics or know someone who does have them open up the power supply and check the capacitors. Often times when a power supply goes bad its the result of capacitors going bad.

If you notice on the ends of any capacitors a brownish/whitish discharge or "bulging" then the capacitor has gone bad.

A new one typically cost less than a dollar and replacing it is fairly easy if you know how to solder.

Let me know if you have anymore questions and hopefully if this is the case you can save some money.

SOURCE: Acer Aspire desktop computer that won't turn on.

This is most likely a power supply problem. sometimes a power surge will cause failure, even when the computer is not turned on. You can replace the whole power supply, or you could check the fuse that is inside the power supply first. on rare occasions the fuse will be the only thing blown, but that doesn't happen often.

SOURCE: Acer desktop mouse,keyboard not functioning, monitor also not wor

If there is no display on the monitor, then your computer is not sending a video signal to the monitor.
This could be caused by a bad video card or some other hardware problem. I would open the case and disconnect all the devices (hard drive, CD, etc. Leave only the CPU, memory, and video connected. You could leave the keyboard and mouse connected too.
If your computer then starts, you can start to add devices (after turning the computer off) one at a time.
If this doesn't work, then you are looking at replacing the motherboard or just the video card if that is possible.

HP Pavilion Media Center m8200n upon turning on it only beeps, and led light blinks twice contiuously, with no signal to monitor?


Power On LED Carl?

I ask that because most Power Supply's that HP uses, have an LED on the back also.
(HiPro, Delta, and Bestec)

The LED is now working as a diagnostic LED.
(Light Emitting Diode, so stating LED light, is redundant)

The beeps you hear are BIOS Beep Codes.
The computer's way of telling you something is wrong, and an area to look into for it.

As stated, it's a Code.
One example;
3 Short beeps,...pause, 3 Short beeps,...pause, etc.

With the Power On LED blinking 2 times, then a pause; indicates,

A) Computer is dirty inside. To include Power Supply

Computer is unplugged from power, Anti-Static Procedures are FOLLOWED; and a can or two of compressed air for computers, is used to clean it out.

I have a procedure to follow if you are interested.

B) Processor (CPU) fan is not seated correctly, and/or is Not functioning, or functioning properly.

Case open, and computer on; see if the Processor fan is;
1) Spinning

2) Looks to be spinning the proper speed.

No, I don't expect you to count the Revolutions per Minute, lol!
My reference is a general one. If the Processor fan looks to be turning slowly, you'll know it

3) Processor fan spins intermittently. Spin, slow down, stop....spin, etc.

C) Thermal Paste in-between Processor, and the finned Heatsink that sits on it, has dried up.
Lost it's thermal conductivity properties.

Top of Processor, and Bottom of Heatsink; MUST be THOROUGHLY cleaned, and fresh, new Thermal Paste applied.

I have a procedure for this too.

I can guide you step by step.

Long and short beeps error?


That's called a "POST" (Power On Self Test) code. I can't find a list of those codes, so I'm guessing based on the symptoms here that you have a dead CPU. Did you have a power surge or something just before it started doing this? One thing you try is taking the cover off, unplugging it from the wall outlet, push the power button to drain the capacitors, then remove and re-seat the memory, then put the cover back on and plug it back up and try that. There's a small chance that something has happened to make the memory come loose or something, but that's not likely considering the problem you are describing. Most likely is that your CPU is dead, which means it's time to get a new computer. A good computer shop can transfer your files from your dead computer to your new computer using a USB hard drive adapter.

Computer wont start


The Beeps you are referring to are 'POST' beeps ( Power On Self Test ). In this case one long and one short is indicating a Board Problem. Depending on the Age and Spec of your machine this will be borderline to repair or replace. If you had further specs i'd be happy to advise

Green light next to power button stays on - no response from computer, totally frozen for up to 12 hrs, then green light goes off, computer suddenly comes on for 5-10 min then freezes again.


Good day sir, hi, You need a thorough check on your PC.
But first try testing the Motherboard, Processor and Memory module.

As this point you need a friend, that knows how to tinker with your PC

Or you may need to do this.

1. memory testing:
Try replacing a new memory ram module on your PC, get the modules out of the memory slot, and let it be tested on another PC. if good,

2. power supply
Test for the power supply box, remove the 20/24 pin power connector from the mainboard and short the green and any black wire, your fan should blow out air.

3. Test for motherboard.
remove all coonections from the motherboard, except the 20/24 pin power connector, and the 12v 4-pin molex power connector, connect the pc speaker or the thumb speaker on the speaker port, connect a keyboard, clear the CMOS, (or remove the battery temporarily), connect the header panel (power switch, reset, power led) place the processor and memory (the tested good one). power on.


You should hear a beep (good) The keyboard will light up the three leds, then a few seconds, the numlock led.

If you hear 1 long and 2 or 3 short beeps, problem with the display section. Reseat any graphics card. test again.

If you hear continous beeps, reseat the memory, if the beeping persist, replace your motherboard.

If you hear nothing? only fan blowing, replace your motherboard.

I can only give you instructions, you need a someone who knows how to service a PC.

When i turn the computer on it starts then


SOS beeps are post codes the computer sends to alert you of problems detected during start up.

The beeps can mean anything from over heating to bad memory detected. Find out what your Motherboard bio is and check Here. This has a handy beep code listing for many of the common mother boards.
Good luck!
Hope this helps!

System not booting, k8n


Have you tried resetting the bios? turn off the computer and remove the power cable connected to the power ATX power supply, look for the "clr_cmos" jumper and change the settings from 1-2 to 2-3 for approx. 10 secs, then return the jumpers to original settings and reconnnect the power cable and turn on the computer. This was the solution when i had the same problem before. Hope this helps you too.
