hi guys I went away for a few days and turned the computer of normaly,then removed the socket from the wall.. Got back yesterday,pluged it in and its dead!! there is a flickering green light(at the back)under the power supply cable but no other sign of power anywhere...theres also a continuous clicking noise that seems to be coming from the power supply unit. anyone any ideas? thanks Compaq presario intel pentium 4-3 ghz 1 gb ddr-160 gb hd
The powersupply must be dead, replace it with a new one and it should work. you say the green light is flickering on the back and you have a clicking noise coming from it? that most certainly is the PSU. Change it.
