Dell dimension 2400 series...used to shut off abruptly with solid amber light and u would have to pull power cord in order to turn it on. Now it won't even boot, get a green light for a second then straight to amber. Diagnostic lights all solid amber also. Any help would be much appreciated.

ok - the amber light of doom on a dell means one of two things - either your power supply is pooched - or your motherboard, If under warranty dell will send out a friendly tech to replace them - if not it will cost you a bit. get the price and consider if it worth upgrading instead. Contact your dell rep or dell tech support and see what they say

Hi you've either got the wires on the wrong connectors or they need to be turned around, i.e. red needs to be where black is. Hope this helps

1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

Steady amber power LED is indicative of a problem with the motherboard. Remove all external connections except power, remove all PCI Cards, ram, disconnect power from all drives, turn on see if power LED is still steady amber. If it is, more than likely the motherboard has a failure. Also check to see if the CPU heatsink is firmly seated (The plastic retainer has been known to fail causing the CPU to overheat)
