This usually means either bad Ram or bad Onboard Video. (Usually the Vram) The only way to test is change the RAM, if, AFTER the fault exists, without HDD connected, then the MB has gone faulty. But most likely it is the MB itself. Also before writing it off you should really try it on another power supply too, real wired things can happen with a bad power supply, that seems to be otherwise, fine, but when replaced things work correctly.

I have an Asus P4s533 vm motherboard which is giving me proplems. During boot up it gives me a series of continuouse beeps and nothing si displayed. what could be the cause of this?



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.

make sure that your RAM and Cmos battery are securely seated


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 they could be faulty

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

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 3 1/2 inch floppy have secure make sure the connections and are not faulty even the electrical extensions 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 click start right click on my computer so any faulty leads will end up with a computer error

hope this helps you

My computer cannot boot because of long beep


beep code usually means a basic function was unable to start. A basic function might be reading memory, displaying video, or being able to send information to a hard drive. The most common problems that cause beep codes are memory and heat-related failures caused by a build-up of dust in critical cooling areas. Use the beep code tables in this document to help find what hardware component is causing the problem. This might reduce the time required to find the hardware component that needs adjusted, reseated, or replaced. WARNING: HP recommends that these steps be performed only by someone with experience in working on computer hardware. Incorrectly handling sensitive internal components can further damage the computer and can introduce the risk of personal injury. Using the correct environment for working on computers (ESD precautions and tools), use the following steps to isolate and fix the problem:
  1. Turn on the computer.
  2. Listen to the beep code and write it down. Write down the number of beeps before each pause, if the beeps are long, short, high in tone, or low in tone. You can use the other sections in this document to look up the beep code description. The beep code and its description can be used for further Internet research if needed.
  3. Note which fans are spinning, not spinning, or making strange noises. It might be possible to prevent the beep code by setting the fan speed to a higher setting in the BIOS setup utility or by cleaning the cooling fins and vents.
  4. hpweb_1-2_plus.gifhpweb_1-2_minus.gif
  5. Check the case fan and power cable.
    1. Turn off the computer by holding the power button for five seconds.
    2. Disconnect the power cord and then disconnect all external cords from the computer.
    3. Remove the side panel to open the computer.
    4. If the case fan was not spinning, make sure the case fan power cable is connected to the correct pins on the motherboard. Replace the fan if it was making excessive noise or was not spinning. If you had to plug in or replace the fan, replace the side panel, plug in the power cord and turn on the computer. If the beeps continue, continue to the next step.
  6. Disconnect the power cord and remove the side panel and perform each of the following tasks, in order, until the beeping stops. Before starting each task, unplug the power cord and remove the side panel. After completing a task, replace the side panel, connect the power cord, turn on the computer, and listen for a beep code. NOTE: If removing or disconnecting a hardware component prevents the beep code, that component is probably causing the problem. However, a failed motherboard might produce beep codes associated with a component other than the motherboard.
    1. Clean cooling components that have become clogged with dust. If beeping continues, continue to the next step.
    2. Remove a memory module. If the computer stops beeping, the memory module might be bad, is the wrong type of memory for the motherboard, or was not fully seated or connected. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module. Remove each memory module, replacing the one that was previously removed. If beeping continues after checking all the memory modules, continue to the next step.
    3. If the computer has a graphics adapter, remove it. If the beep code changes or continues with the same beep pattern after removing the graphics adapter, the adapter might still be good. Reseat the graphics adapter into its socket and continue to the next step. If the beep code goes away, the graphics adapter might be bad. Try reseating the graphics adapter, making sure it is fully locked into the connector on the motherboard. If problems continue, replace the adapter.
    4. Remove a PCI card. If the beep code goes away, the card might be bad. Try reseating the card into its connector on the motherboard. If problems continue, replace the card. Remove each PCI card, replacing the one that was previously removed. After checking all cards, if beeping continues, continue to the next step.
    5. Disconnect hard drives and CD or DVD drive cables (IDE and ATA) from the motherboard socket. If the beep code goes away, the cable or socket is probably bad. Look for bent pins inside the IDE socket on the motherboard and straighten any bent pins. Try reseating the cables into the connectors. If problems continue, the drive itself might be bad and might need replacing. Disconnect each drive cable, replacing the one that was previously disconnected, until all have been checked. After checking all connections, if beeping continues, continue to the next step.
    6. At this point, the problem is probably the motherboard or processor. Make sure any jumpers on the motherboard have not fallen off their pins and into the case. Make sure jumpers are set correctly. Otherwise, have the computer serviced by HP or by a qualified service center.

I have a Dell 1525 laptop and when powering up, nothing comes up on the screen but the power light comes on. One time it made a loud beeping nosie.


It depends on the beeping noise you hear. If it beeps short but continuouse then it is probably power problem possibly the battery. You can use a guide to the beeps to determine what exaclty is causing the probpem it might well be the hard drive is gone.

My Screen is blank and fan continuously runs.


your computer is not posting that is why you do not hear a beep. This can happen for 1 of 10000000 reasons but I would start with checking the RAM then all the other hardware to find a loose connection/dead hardware.

Constant beeping


I would first check that all the fans are turning when you first power it up. It may have fan speed sensors on them, and one or more fans aren't coming up to speed. I would check the CPU fan(s), as they are usually smaller, and tend to go bad before the other larger ones.

Machine emits continuous high pitched bleep and power light flashes blue/red


If working OK, probably means that the temperature alarm goes off because is getting hot the PC. I suggest to check why is that happening. All fans working OK? is the CMOS temperature alarm set too low? check your motherboard instructions booklet- It will tell you what the beeps mean probably in the last pages. Good luck
