No boot or beeps

My pc just recently started having some problems. I turn it on, and the fans would come on and also all the components (hard drive, video card etc.) would power up. However I would recieve no beeps or video to my monitor. I have tried every thing I can do with the resources I have, save for buying a brand new mother board. I have replaced the CMOS battery, reset the bios, disasembled my computer, and cleaned off every thing. My final analasyse is that my mother board is just dead and needs replaced. However I get the feeling that thier is somthing that I am not trying. My mother board is an ASUS P4P8X. Any help would be greatly apreaciated

    The same thing started happening with my Medion last night. No boot/beeps. The fan just blows continuously. Did you ever determine the problem?

My computer beeps but does not start


Those beeps are telling you what is wrong. Most times it's the memory or video card.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.


Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.


Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

I installed windows 7 on my lenovo g460. After installation It cannot boot from harddisk. The LED light of HDD is turn on when pc starts and as soon as it comes to boot device selection it becomes off.


First reseat the hard drive. Next make sure you have no USB or ESATA devices connected to the laptop as the system could be trying to boot from one of them. Another possibility is that the hard drive could have failed. (when you install an OS you put the hard drive through a lot more stress than you would during normal use. If the drive was on the verg of failing that could have pushed it over the edge). There are built in hard drive diagnostics that you can run. Consult your owners manual or the Lenovo support site for a how-to guide.

One short beep one long beep continuous and power green led flashes continuos


I would say you have a failed memory (RAM) module. Probably a module in one of the secondary slots since the computer is able to POST and will attempt to boot.

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 detect/ boot up a computer hard drive

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 even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as an electrical extenion or a faulty fan lead can cause this problem

hope this helps

Your computer is not POSTing. Reset the BIOS/CMOS to defaults by removing the BIOS/CMOS battery and then reinstall it in the correct orientation. If it beeps at you once when turning on then it is working, however if not then in my experience it's the mainboard that is faulty. Ensure that all the connectors are indeed making contact and are correctly seated. You can also power on your pc without RAM installed. Now your PC should beep at you! If it doesn't then this confirms that the mainboard is faulty.
Also try powering your PC with the least components as possible. So ideally use onboard VGA, disconnect all hard drives and cd drives, use only one RAM card, use them alternatively.

Replace your PSU then test all leads that are attached to your hard drive sounds like a faulty lead of some sorts then
try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
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 because a computer has to have an end to the circuit any fulty leads will lead to no boot up
good luck

System can't boot after performing a PC clean up by dissembling


beeps on start up is indication of missing hard drive. memories, or reversed IDE cable.
unplug all add-ons, leave just the memories and the monitor. turn on the machine. if all is good, then insert each items one at a time.
make sure the memories are the type that fits the machine (not physical but electrically).
I suspect your hard drive may be the problem.
go to BIOS and make sure all the items a checked and correct. specially the drive0 and drive1.
I assume that the hard drive is SATA. make sure the connection is 0 to 0 and 1 to1 in the BIOS.
check the hard drive in the BIOS, make sure it can detect the hard drive. if so, then the problem is in the hard drive. if you have another hard drive, try that one.

My computer wont turn on it just keeps making a beeping noise it doesnt stop till i turn of the power


Usually it is a loose component or a bad component. Usually a memory card or a hard drive that isn't plugged in all the way.

Check your connections.
