Motherboard keeps beeping and doesn't turn on, anymore. I've tried replacing the Power Supply unit and it still hasn't solved the problem. I can't locate the original manuel which gives all the error codes corresponding to the beeping sounds. Please help.

Have you tried reseating the memory? Sometimes that can cause weird problems when its not in the slot all the way.

How can you check power to computer

Does your monitor light up, if so, swap the lead into the tower and if it still won't turn on then you know it's not the lead.
It could be the power supply, you could try swapping for a known working unit to check.
If still won't start, then unplug everything from the motherboard (except the power supply) and turn on. It should start making lots of beeping noises. If it does, replace each plug in turn till it doesn't then you know what to replace. If it doesn't, it's probably the motherboard that's faulty.

When I start up my computer, nothing happens. The hard drive doesn?t spin, the fans don?t work, nor do I get any display. I?ve checked the power strip and know that power is getting to the computer, but...

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to boot

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

My pc had no power

First to be check is your power cord and the line. If it's ok, then check the power supply.Power is indicated by a fan at the back of your CPU case. If there's no fan activity, power supply is busted. Replace power supply. If the power supply is good, there should be a beep sound indicating that the motherboard is good. If there's none, isolate the board by removing all devices (hard disk, cards, memory, etc) just to see if the motherboard is working right. Power on again, if there's a beep, you may reinstall the rest of the devices you removed.

Will not turn and will not stop beeping

Beep codes can tell you what is wrong with your computer. (Assuming your motherboard uses the IBM codes that many manufacturer's use) If the continuous beeping involves long beeps, it's a memory issue. Pull out and reseat the sticks. (Try them one at a time). This involves opening the case, pushing down the clips on the ends of the memory stick and then pulling them up and pushing them back (keep the orientation the same and aligned). The memory is fully seated when the clips pop back into the memory stick's edge (there is a little shaped area that the clip fits into.).

If you here high-low beeps, then you have a CPU overheating issue.

Check your manual for the specifics on your machine's BIOS and then you can search for the beep codes for that motherboard.

I hope this helps.

(IBM is the only one with any continuous beep codes that I know; most codes have a repeat pattern with a short break to indicate the end of the code)

Dell Inspiron 531 (desktop) won?t turn on/boot

You've either got a bad motherboard or a bad processor (I'd lean to the motherboard being bad). I would honestly take this into a computer repair shop and have them check both.

When turning on the power everything starts as normal but then the system stops and beep. The fans keep turning but you can no longer hear the power supply going.

Either the power supply is bad, or (if you're getting two or three beeps) your memory is bad. If you get one quick beep and it shuts down, your video may be bad. How many beeps do you get?

I have a hp pavilion 513c it wont boot up! the


There are only two ways this can go for you.

One- you need a new power supply


Two, you need a new mother board

You can verify the power supply by checking it on another machine

If the power suppy is good

And you do not hear the bios beep- then you are looking at a new motherboard- I would double check the powersupply first- most stores that sell them will let you check before you buy a new powersupply.

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.
