There seems to be two issues here, the front switch on/off button, should turn off if you arent getting any video to the monitor, unlike when booted into windows when you have to press and hold the button in. there could be a number of reasons for the monitor not coming on, but if you cannot get into the bios (f2 or Del on boot up) the cmos chip is corrupt or faulty and require that you clear the cmos by the CLRCMOS, JBAT1 terminal, refer to your manual for the exact terminals and try re booting the pc. if you can get into the bios, go to advanced cmos settings and ensure that agp is set as primary graphics adapter if you have a graphics card, or pci, if not vga should be set as the primary controller. Also check that the motherboard is not touching/shorting on the pc casing, and that the memory that you are using is compatable with the motherboard normally signaled by one beep, proceeded by another for the graphics.

Wll it could be your pci controller is damaged.. (In thic case the only solution is to buy a new board)

Or you bios might need flashing..

Unplug your system
Open up the system,
put back in your network card
remove the battery on the main board
hit the power button 7 times
replace the battery
plug it back in and try to boot now

When it boots, you need to enter the setup and load your default settings then save and exit..

In short, yes you can upgrade to a P4 cpu but from the compatibility chart at Intel support, it looks like the upper limit for this older board is the P4 2.6GHz.

Note: Even at that, running the P4 2.6 would require a BIOS upgrade to P12 or greater.

Luckily, the following link has the information you seek: (for BIOS info, click the "BIOS Version" link in the upper right corner of the compatibility table provided)

This board I think is an OEM board built by Asus for HP computers. Also named Pegasus.
Go here to find a PDF manual for that particular board -
On page 22, the last page, it shows you the pin-out for the connections for the front panel, ie - power button, reset, led's, etc. Hope this helps.

Make sure the video card is good and also that it is seated in the slot properly. You may need to actually remove it from the slot and push it all the way back in to reseat the card to make sure it is in all the way.
