Turn on computer and 1 beep no display fans run

The beep signifies an error. But different bioses have different beeps. You can check with the emachine site to tell you what 1 beep on the machine signifies and you can be guided accordingly. Could be bad power supply, connection, peripheral, etc

Hi

THe most common beeps that you will encounter 95% of the time in repairing PC's are:

1 beep - computer ok
continous beeps / long beeps - memory error
continous short beeps - bios boot block/corrupted bios
1 long beep followed by 3 short beeps - video card error


or this might help

you can check out this list



AMI BIOS

1 short - Computer ok
2 short - RAM failure
3 short - Parity RAM failure
4 short - System timer failure
5 short - Motherboard failure
6 short - Keyboard controller error
7 short - CPU failure
8 short - Video RAM failure
9 short - ROM BIOS error
10 short - CMOS read/write error
11 short - Cache RAM error
1 short, 3 long - Memory failure
1 short, 8 long - Video adapter failure

Check board/chipset makers website for more infomation.

AWARD BIOS

1 long - Memory error
1 long, 2 short - Video error
1 long, 3 short - Video failure
Continuous beeps - Memory or video failure

note that AWARD relies on motherboard manufacturers to develop their own beep codes - the above are only their own internal codes. You will need to refer to your own manual for an explanation of precise codes.


Standard IBM beep codes.

No beep - Power supply or motherboard failure
1 short - System is ok
2 short - POST error (code displayed on screen)
Repeating short - Motherboard failure
1 long, 1 short - Motherboard failure
1 long, 2 short - Video display adapter failure
1 long, 3 short - Video display adapter error
3 long - Keyboard error


Pheonix beep codes

1-1-3 CMOS memory failure
1-1-4 BIOS failure
1-2-1 System timer error
1-2-2 Motherboard error
1-2-3 Motherboard error
1-3-1 Motherboard error
1-4-1 Motherboard error

4-2-4 Expansion card failure
4-3-4 Time of day clock failure
4-4-1 Serial port error
4-4-2 Parallel port error
4-4-3 Math co-processor error


pls rate as fixya if it helps. thanks

- First of check is your RAM inserted in ports correctly?
- Clean the Processor fan, Heat Sink and other peripherals.
- Use High Speed fans.
- Start PC in safe mode.
- Download program PCFresher.
- Run its all tools.

Your problem will be solved.

It could be that either the graphics card or the memory modules may need to be re-seated. Those would be the first things to try.

No Display, so does it seem like the computer booted up and is running except that the Display is black? Do you hear fans running, disk drive spinning, blinking lights or beeps?

I'm going to assume that in your case since you mentioned a red light that it is not booting up all the way. Therefore your problem is probably with the memory, the video card or some other motherboard issue.

Remove the Power Cord, Remove the Battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory 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 onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

MY DEAR FRIEND


CAN you tell me the what is the display problem

OK

Memory failure. Try using another DIMM.

first shut down you computer remove the covers of the cpu then locate the memory and remove them wipe them clean with clean cloth and switch the computer on with out the memory and see if you hear any beeps if you hear beeps insert the memory and switch on the computer if still no beeps then remove the processor fan and clean the surface of the processor fan and the processor apply a thin layer heatsink solvent and clip the processor fan tighty to the socket

different beeping patterns are codes which indicate what part of the hardware has failed (ram, video card, cpu, ect). the fan failure would not cause beeps, and would not cause the cpu to fail unless already in windows. if you could find out the manufacturer of your motherboard you could check with them about what the paticular pattern of beeps which you are getting mean.

how to fixed your motherboard no display and no beep, 1st you must clean your memory using eraser and brush for painting if not display again try to clean your video card if have a video card using again the eraser and painting brush if not display again try to pull out the bass in the cdrom and floppy disk. if not display you must replace the memory and video card., if not display try to change your motherboard. The beep put speaker in the motherboard.. gudluck guys
