Computer will not boot up and green monitor light flashes

We had a major power failure today. When power was restored I tried to restart my Dell computer. CPU does not seem to be booting up properly and monitor screen is black and the "on" light just keeps flashing on and off.

    NUM LOCK, SCROLL LOCK AND CAPS LOCK are all solid green when I press them ( no flashing) but the monitor "on/off" still flashes green. Also, no DELL logo (screen is black). I think is right, time to change the motherboard. Looks like power outage fried the MB even though I was using a surge protector! What do you think?

    Do you get the flash of the NUM LOCK, SCROLL LOCK, AND CAPS LOCK, at turn on or reboot? How about a splash of Dell logo?

After automatic updates and a restart, diagonstic lights A & C were yellow and D & B green, nothing comes up on screen, this happen before after an update but i got it to start after several a


If all diagnostic lights are on, then that means that it has something with the software of your computer. The update has affected some of the programs inside your computer thus it's booting up fine.

I suggest that you access safe mode and do a system restore from there. If you don't know how to access safe mode, then follow these:

1. Turn off your computer.
2. turn it on and keep tapping F8 until you see the options. You should see safe mode.
3. Use the arrow keys to select safe mode, then press enter.
4. Your computer should boot up to safe mode.
5. Access the system restore. You can find it in accessories, system tools, system restore. or you can search.
6. restore your computer to the known good date where your computer was still working fine.
7. After completing the on screen procedures, let your computer restart by itself (it may take minutes or more). It will restart and it should boot to the normal windows.

Good Luck!

I hope this helps.

My dell optiplex gx620 does not start and it shows no. 3 and 4 lights illuminated on its front . what could be the problem.?


One of your memory chips is bad.

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.

Diagnostic Lights caution.gif CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4"on the front or back panel. The lights can be off or green. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. When the computer starts normally, the patterns or codes on the lights change as the boot process completes. If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted.
note.gif NOTE: The orientation of the diagnostic lights may vary depending on the system type. The diagnostic lights can appear either vertical or horizontal.

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

What can cause this error?

Well, this is the problem since quite a variety of problems can trigger the error.

1: the bios can be malfunctioning (a bios reset or flash can give a solution)
2: the cpu can be malfunctioning (this requires a new cpu)
3: the cpu socket can be failing (this requires a new mb)
4: the problem can be with bad usb sockets
5: even a bad uplink to a usb hub can cause this error to appear.
Did you change your monitor lately? I would chase down the USB things first...that and the monitor seem to trip the trigger...
Hope this get you started- I think you were right on target with the flash of the BIOS-try it again using the BIOS flash downloaded from the dell site...and to run the chipset again...it just might
Good luck my friend, hope this helps, please leave rating, thank you kindly

Dell E228WFP Monitor failure


To me, that's an XP driver issue. If the screen turns on at all, then goes dark during XP boot, that's nearly a ringer for drivers.

Out of range on the Hz? Tried booting in safe mode to see if it loads with standard win drivers? That might work. Reset the monitor to default/standard settings and try safe mode is what I would do. Ramp up the resolution/refresh rate from there.

Monitor flashes on and off!


Sounds like you have a bad connection from your monitor to your computer. First check and make sure the connection between them is tight. Does your computer boot up and run though? If your computer is not booting up the monitor will default back to the flashing green power light
