Yellow power light on HP SR1420NX

\015 I can turn the computer on and hear the fan running, but the power light is yellow (always been green before today) and the monitor immediately goes into power save mode and shuts down.Can't get the computer to boot up. Was working fine as of last night, this started this morning.\015

Answers :

For reasons yet to be determined, your computer is not talking to your monitor.
\015\012This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.
\015\012Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.
\015\012Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.
\015\012Good luck
