First off, despite very clear graphics on the HP site, you posted this to the wrong section -- the Desktops section -- which may be why you have not received any replies to date.
Second, I wish we could help you from here, but we can't. The problem is that we HERE, have no way of diagnosing or repairing hardware problems. And, with the PC not even starting, even HP Tech Support, who have the authority and tools to REMOTE into a PC across the Internet, can not access your PC.
Software failures invariably present with error messages of some kind on the screen, such as No Operating System or No Boot Device. In these cases, reinstalling the OS from media such as DVD or USB fixes the first; rebuilding the boot records using various utilities fixes the second. But any time a laptop simply refuses to turn on, that tend to indicate a serious hardware failure.
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then you should contact HP Customer Support to see about having it repaired or replaced under warranty.
If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1
If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html
NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!
If you have trouble finding a phone number, then try: 1 (650) 857-1501.
Tech Support's number is 1 (800) 474-6836.
If your PC is no longer under warranty, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.
