Just because the light is on doesnt mean it has engough power to start all the components... Try opening the computer and unpluging the things you dont need to start the pc. ie cd rom drives, pci cards floppy drives, ect. If it boots than it is deff the power supply if not it may be either the power supply or motherborad or cpu!

My monitor no display and light is blinking


Hi,
if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .

1. Bad video card 2. Bad video software

To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.

If the light changes to green and back to amber the video port on the tower is bad

Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.

Thanks for using fixya

Sounds like a dumb question, but I was moving my comp to lean over and change a printer cord and the comp shut off. I have checked all the power cords etc, but when i press the on button the comp does not...


There is usually a reset and a ON button. the latter being larger was that one tried?
If you have a battery UPS you might have turned that off and it will only supply battery power might not be enough to turn unit back on.

Tower won't turn on. There is a green light on the back near the power cord that's flashing green.


Pull the power cord out and allow it to reset. If you still have issues you may need to replace your power supply.

My Dell 8200 Desktop just stopped working. It turns on but doesn't boot; nothing appears on the screen. I was told this is the motherboard. Does that sound right?


two things
  1. What does the power LED on the tower indicate? Solid Amber? Flashing Amber? Solid Green?
  2. On the back of the Tower are 4 diagnostic LEDs, what do they indicate? Normally they flash thru several sequences and stop ABCD all Green. If the stop in another pattern, post the pattern.

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

Green light blinking screen blank


Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.
