You more likely had a temperature issue with the CPU.
Had the CPU fan started to sound like an airplane warming up?
If so, you may have finally burned out the CPU.

Yes it's possible that it was reporting a problem with the power supply, but the only way to know for sure is to replace it.

In the meantime, eliminate everything else.
Disconnect power from EVERYTHING except the motherboard.
If it powers up, then it's possible that either your motherboard is failing (and now works under the decreased load), or one of the things you unplugged has failed.

If the unit springs to life, turn it off, and start reconnecting things.
If it fails constantly whenever 1 specific thing is plugged in, that thing or the motherboard chip that controls it is the problem.

Led light is solid on my dell xps 400 and system wont start? any ideas?


Can you be more specific when you say the system won't start?

If the system does not turn on at all or turns on for a second and then shuts off it is very likely due to a power failure. If you have installed any new harware recently unplug it and try to start the system again. If problem persists it is likely faulty power supply which a fairly cheap fix.

Xp420 dell doesnt boot just a solid amber light on mother board high rpm on fan that doesnt slow no picture on screen....?????


Solid Amber light is a No-Boot scenario for all DELL PC. It may be either Power Supply, motherboard, memory or Proc. If you try to call Dell customer support they might try to let you isolate the problem by opening up your pc. But they will replace the parts necessary if they found out that its broken and your XPS is still under warranty.

You can call 1-800-232-8544 be sure to have you Service Tag or Express Service code ready.

Why did my xps 400 just quit, The only thing that works on it is, the cooling fan at high speed


The fans running full tilt are an indication of a NO POST failure with the motherboard.

The POWER LED on the tower, is it Solid Green? Solid Amber? Flashing Amber?

The diagnostic LEDs? (Numbered 1234) are any illuminated?

General trouble shooting is as follows:
  1. Power system off, disconnect all external connections except the power cord, turn the system on see if any change. If you get a change, reconnect items one at a time till you ID the failure. (Twice I've seen a bad mouse cause a no post, so don't assume items are good) If no change go to step 2
  2. If no change, then POWER LED is likely a solid amber. Open the tower, remove all PCI and PCI-E cards, see if the symptoms change. If they do, like before add items back one at a time till you ID the failure.
  3. Disconnect power to all drives, see if anything changes ....
  4. Remove the RAM, see if there is a change, if no change then replace the motherboard. If you get a change, try RAM modules individually see if one is faulty.

I have a Dell dimension XPS 400/9150, 3 years old. I did updates and shut down. Tried to restart, but all I got was a flickering amber light. Won't start at all. Now no light.


Sounds like your power supply just failed. Unplug the power cord, open the case, and look for a metal box inside the case right where the power wire plugs in. Remove the box...usually four screws hold it to the case, remove all of the wires...marking each one and the motherboard so you'll be able to connect the new power supply wires. Most computer stores will have a suitable replacement. Easy replacement if you mark the wires/connections during removal. Just be sure to work with the power plug removed.
