My Dell inspiron 531 which is about 6 years old yesterday w hen I was working went off since then when I switch it on first amber light comes on then blue light comes on very briefly and then computer goes off completely but green light on the back of the unit stays on. Any idea ? Will be appreciated. By the way 'no beep'.

Disconnect the power, open it up and disconnect the leads to the drives. Remove any expansion cards such as enhanced video or extra ports and connect the monitor to the onboard video port.

Reconnect the power and try to boot it. If it fails the startup check it could be the motherboard or the power supply.

If it passes the motherboard check then reconnect the hard drive and test again.

Put any other stuff back in one by one and see when it fails.
