    Hello again have you tried unplugging all things unessential. first unplug everything plugged into the pc from the outside. and try starting it. If that doesn't work you could try and unplug everything from the motherboard , keyboard, mouse, all your Hard drives and optical drives included also any unessential adapter cards. use one stick of ram at a time and see if you can get it to post if you have success then start adding (plugging the pieces back in one at a time until it fails to boot to identify the culprit. let me know if this does anything for you.

    Hello Does the keyboard work at all? it does sound to me like keyboard failure or part failure anyway. but we can try a few things to trouble shoot if it is the pc or the keyboard. Is the keyboard connect to your pc with ps2 or usb? If it is ps2 have you tried a ps2 to usb adapter? Which lights are flashing? Do they eventually stop? Is there a key stuck down? Is there software installed that came with the keyboard? Do you have another keyboard you can try? if it is usb you could unplug it and plug it back in, while the computer is running. it may refresh the driver. you could try to delete the keyboard entry in the device manager and "rescan" the computer " (with device manager) and it WILL refresh the driver. post your answers as a comment and I'll be notified thank you

If both are not working, then you need to replace the keyboard entirely.

PCI simple Communication Controller

Drivers are here:
Just click evo d510 cmt, then download drivers and software.

You should now be at a page that lists all of hp's drivers for your system.

I think PCI simple Communication Controller would be your modem, which I saw on that page, and also the driver for your ethernet controller.
