The blinking amber light is a sign of a power supply issue. We own over 50 dell pc's and have discovered that the fans in the power supplies go bad and what happens is that the computer starts up and at some point the fan stops blowing. Then the power supply eventually overheats and then the high temp sensor shuts the machine off. I have detailed how to repair this type of thing on my website: John Fixes Stuff How to Replace the Power Supply Fan in Dell Optiplex GX520

It sounds as though your computers hibernation feature is malfunctioning, or your power setting are set to shut your computer off. If I were you I would attempt to disable both features, Go to Start in the bottom left, click on Control Panel in the Start menu, and then go to Power Options. Basically just tell it to never shut off any hard disks or the computer.

I'm not clear about the blinking amber light you are referring to. Is it on the computer or the monitor.
I checked Dell's web site for the service manual for this computer model, & found this document:

If the blinking amber light is on the monitor, check the connection between it & the computer itself. Make sure the cable is not damaged & that it does not have any broken pins in the socket.

Blinking amber light with green 4 light
If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Try, unplugging the power cable from the pc, and reinsert it, if this does not help try a differnt power outlet, if this dont help, open the computer, take the power Molex conector out of the mother board and try turning it on, if this dont help, take out the Memory modules and reseat them, if this dont work you may want to ring up dell support.

Hope this helps!

Have a yellow amber light blinking
A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. 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.
