    I have Dell XPS 420. My daughter was getting ready to use it last week and saw an amber colored light on the pc's power button, when she pushed the power button to turn on the pc it blinked off and it has not worked since. What can be the issue here?

    If I recall correctly, the Dell XPS 420 desktop is a very old model which originally came with Windows XP or Windows Vista 32-bit.

    Considering how old it is, it's my guess there's an issue with its power supply unit or some other hardware.

    I was considering taking it too the Geek Squad to see if it was something that could be easily repaired before looking to get a new PC.

    The "Best Buy" Geek Squad may charge you more than what that desktop is worth to troubleshoot it.
    And if the power supply unit or some other piece of hardware needs to be replaced, that may also cost more than what that desktop is worth.
    Good luck.

    If u really want to save the dell
    Just replace the power supply
    It’s not hard and it looks like in the pics it’s a regular atx psu
    Can pic up a decent corsair for 20 bucks when they go on sale

    Does it still have the amber light on the power button? Is it blinking? A
    Blinking amber power button is usually either a power supply problem or possibly a motherboard issue.
    If you use a power strip or surge protector, remove those. With the PC off and unplugged, press/hold power button for ~15 sec. Reconnect PC directly to the wall outlet and see if it boots now.
    I F THE POWER LIGHT FLASHES AMBER AND THEN GOES OFF — It can be an internal power problem.
    • Ensure that the processor power cable is securely connected to the system board
    power connector (12VPOWER). (See "System Board Components" on page 103 of manual) http://ftp.dell.com/Manuals/all-pro..._xps_desktop/xps-420_owner's manual_en-us.pdf
    My friend had a refurbished Dell 780 and it had a solid amber light, ended up being the motherboard went bad but I was able to replace it for $35.
