Blue. Light keeps flashing


IF THE POWER LIGHT IS BLINKING BLUE - The computer is in standby mode. Press a key on the keyboard, move the mouse, or press the power button to resume normal operation.

Vostro 420 flashing power light


A steady or Amber blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

My Dell Vostro 420 processor is not coming on, when I press the power button, thre is no power


Are there any blinking lights on the back of the computer near the fan or power cord? If yes then it sounds like your power supply is bad. You can get a new one for about $50 - $60.

Amber light on the front, PC not booting up


Usually a flashing amber light means the power supply is bad, If its solid its probably another device on the system board that could be bad or not installed correctly.

Hope this helps

Xps 420 keeps freezing or going to blue screen


Same with my Dell Vostro 420. At this rate I will just buy a new PC as I am wasting too much time on this. We tried usual stuff like cleaning inside, making cooler, removing certain virus software, still no luck. I have to restart 4 times a day and keep saving material. Can only restart by turning it off by pulling out power socket.

Fixed amber light - start,shut down itself and restart itself Hello, Yesterday morning, I have installed a second screen linked to my graphic card. I tried to install a 3rd screen on the VGA motherboard, and it didn't work so I take it off. I could work on the computer with the 2 screens all day long. I left my office and the screensaver started. When I came back, I couldn't started my computer and my screen didn't light on after moving the mouse or writting on the keyboard. Then, I shut down my computer to restart it. Here is the problem. 1) The power light was fix and amber, the ventilation works. 2) 2-3 seconds later, it shuts down itself for few seconds 3) And it restarts itself. However, I still have the fix amber light and the screen is not activated. I checked the wall plug, I reduced the number of device on the trailling socket. I removed and reinstalled from the motherboard the RAM memory card and my graphic card. I tried with only one screen. But I still have the same problem. Do you have any ideas about what the problem could be: - Is the motherboard over? - Is the graphic card over? - Is the power bloc over? How could I evaluate which component is not working correctly? Thanks for your precious help. My configuration : - Intel Core 2 Quad Q8200(2,33GHz,1333MHz,4Mo) - Windows Vista - Cordon d'alimentation : Européen 2M - Carte graphique : 256Mo DDR2 ATI Radeon HD 3650 (pleine hauteur,sortie DVI/HDMI/DisplayPort,Double affichage)
