Basically, I think that your power supply has gone bad if nothing at all happens when you turn it on.
To test this, disconnect the hard drive, the CD, and any other peripheral and try to start it.
All this assumes that when you push the on/off button, all you hear is yourself breathing--nothing at all from the computer.

Unpluged comp still on now wont come back on power getting to it seems to be on stand by can not get back on help


If all plugs etc are connected correctly and it is in standby, press the power switch momentarily and it should boot up. If not press the power button for 5 - 6 seconds and if that doesn't work there is a problem with possibly the power supply.

Not booting, blinking light


4 blinks, 1 second apart is a power supply overload. Have the power supply replaced if you haven't added any additional hardware lately. But also make sure your hard drive isn't bad and pulling an overload of power. it's rare, but I have seem that happen on some western digital hard drives.
