Question about Dell Inspiron 560 PC Desktop
When i power on it blinks once amber then goes black
This could be either power supply or motherboard problem. If the fans on the motherboard and power supply are spinning then it's probably the motherboard which you can check by removing the memory and unplugging the data lead off your hard drive. It should start beeping.
If not, then it's probably the power supply. They are easy enough to change - half a dozen plugs and four screws. I always replace standard power supplies with a 400 watt one. It will tell you the wattage on the label, I would add 100 to that figure and get that size or bigger - depending what's available.
It will not hurt to replace a 250 watt unit with a 500 watt unit so don't worry about that. It gives you room for expansion.

FIRST IF YOU REPLACED THE POWER SUPPLY OF YOUR DELL PC,
MAKE SURE IS A RECOMMEND POWER SUPPLY FOR DELL COMPUTERS ONLY
BECAUSE DELL USE A DIFFERENT (NONSTARD) PS
AN PLEASE DON'T TURN YOUR PC ON, TILE YOU ARE SURE I'TS A DELL COMPATIBLE POWER SUPPLY
YOU CAN FRY YOUR COMPUTER
ON THE MOTHERBOARD I'T MAY BE THE BIOS (BIOS STANDS FOR INPUT /OUTPUT SYSTEM) I'T A CHIP ON YOUR MOTHERBOARD THAT CONTROLS THE SYSTEM HARDWARE AND ACTS AS AN INTERFACE BETWEEN THE OPERATING SYSTEM AND THE HARDWARE
I'T MAY BE FLASH
IF IS FLASH ,
YOU PROBABLY NEED TO REPLACE THE MOTHERBOARD
OR CALL DELL TO SEE IF THEY CAN FIX IT

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.
