Pavilion slimline light come on but no signal on monitor

[dellyenergy]

the monitor is fine for sure but it says no signal when I turn on my pc. The hard drive don't run I think either as the orange light don't flash nor do I hear it running. Only the fan runs. The keyboard light only flashes at the point when I push the power button. I use the monitor on other pc and it work fine. I can eject the DVD drive tho while the light power light is on. What's wrong, please help!!

I have tried the steps. Resetting the bios. The keyboard light don't stay on after I press the power button which would indicate that those components aren't running. only 1 flash. I tried all the steps and still no display.

A lot of hp slimline main board were manufactured with a defect. Hp have extended watenty on these models that they have listed. I spoke to several online techs that eventrually deemed my pc as having such problem due to the problems that I described and the results of all the routine trouble shoot procedures that they asked me to carry out. There is a particular link that describes the situation, and that they have extended the waranty period for such models till dec 09. I got them send me a return box for me to get the part replaced. Pretty neet afterall. I can't post the link because I'm using my iPhone therefore can't copy the link.
