HP 514c Boot problem

Here's the problem, it's an HP 514c, When you hit the power button the power light flashes amber/orange 2 times then turns to black. the fans inside the case all turn on, the cd rom activity light turns on and flashes like it's checking for a cd.. the light for the floppy drive never flashes. The hard drive sounds like it spins up but then turns off. the fans go to a slower spin, almost like an idle, and it sits there and does nothing else. The monitor never gets a signal, the amber light on the monitor never flashes or changes to yellow/green. Also there are no beeps after you hit the power button.

Originally the power supply fan was dead and i figured possibly the supply was dying and only giving partial power so i replaced the powers supply w/ a part from HP. This brought no change.

I then called HP and went through some steps with them to no success.

I then replaced the entire motherboard with one supplied by HP... Still the exact same problem.

With a new power supply and motherboard... i'm really running out of ideas as to why on earth it wont boot up at all, no signal to monitor, no beeps, etc...

ANY ideas advice please let me know... i'm dyin here

Hi,

I would have suspected the psu also so that was not a bad choice to change it.
Are you sure there is a case speaker connected some of the hp's I worked on did not have one, it would be helpful if it would beep that why I am checking.

Try removing all the drive connections both power and ide cables, also remove all cards, the idea here is to try and get into bios/setup, if you can then one of the components removed is the problem.

Does this computer have a video card or is it onboard?

Well i searched the inside and there is no visible speaker anywhere, however there is kind of a space between the front panel and the power button that may hold a speaker but i doubt it.

I disconnected all of the cables and hit the power button, same exact response...

Also i forgot to mention previously that i changed the memory w/ brand new out of the box memory and got the same result.

The vid card is onboard, thus replaced when i replaced the mobo.

thanks for the ideas... any more? With the components i've replaced its seriously come down to... the processor? is it possible it died? wow i have been fixing computers for a long time and i honestly am baffled.

Yea it looks as if its the cpu everthing else has been replaced, take it out and look for visible signs of burt edges or other things but it could still have died and have no visible sign

You could also take the board out of the case with minimal components installed and try and start it this would eliminate the possibility of a case short but I doubt it is that
