NO DISPLAY on screen but processor fan is work


If it seems like the computer booted up all the way except the screen is blank.

If so try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok and works, then the video card inside the computer is good, but the original monitor is bad. If the Borrowed monitor does not work, then the video card inside the computer is bad.

If it does not seem like the computer booted up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the computer?

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 computer 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.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

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

Remove the Power Cord, Open the Case and 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.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

Sounds as if your hard drive may be bad. or you have a Bios conflict.

Check the jumpers on the drive to make sure they are right.

NO POWER


If you have changed the power unit and the computer is still not powering up, then it is quite likely there is a motherboard fault - probably in the power management circuitry, which expects the power_good signal from the power unit at a precise moment in the boot up process. A fault in the power management circuitry would prevent the computer from beginning its boot-up process.

Do the fans in the power unit come on when the computer is switched on? If they don't - this suggests a power unit problem. If the power unit fans do start working but the computer still doesn't boot, this suggests either a faulty or 'dry' connection (easy checked) or a motherboard fault.

If your computer 'works' but nothing is displayed, try pressing Control+Alt+Delete. If it then boots up it suggests a power unit problem. If not .. we come back to the motherboard again.

A low wattage power unit can cause the problem you describe. Every 128 Mb of Ram needs 4 watts of power. Add more for the motherboard (up to 30 watts..) then the floppy/hard drive/dvd etc .. If the power unit can't supply the necessary wattage, it won't boot. The older 250-300 watt power units aren't suitable for modern computers with XP/Vista. Ideally, you should be looking at 400 watts plus -it will tell you on the power unit.

Though to be honest, it does sound like a motherboard fault.

The only other thing that can cause a computer not to boot up (though it will begin the boot up process) are other faults ... When you switch on does it actually display anything on the screen .. and are there any 'beeps'? 1 beep indicates everything is ok .. 3 short beeps and 1 long beep indicate a memory problem (and the computer won't boot..). 8 beeps indicate a video problem (and nothing will be dislayed on your screen). Same with 9 beeps .. which indicates a bios fault - and the computer won't continue the boot process.

If you have nothing .. no power whatsover ... it comes back to the power unit/mainboard. If you're happy that the new power unit you have put in is ok ... suspect the motherboard. If you have access to any unwanted or 2nd hand motherboard ... connect that. If your computer boots up ... its the original motherboard at fault.

Alternatively, rather than replace bits and pieces at random to cure the fault, take your computer along to a computer shop. It will take them minutes to test it for you and identify the fault.
