Try a hard reset. Remove battery and AC power. Hold down the power button 30 seconds, wait 30 seconds now plug it back in and see if it starts. Sometimes a failed sleep or hibernate state will cause this and a hard reset is the only way out of trouble. If the hard reset does not work post back and we will try something else but the sledding gets real difficult at that point. Likely hardware issue.

I had the same issue with same machine loaded with W7 Home Premium, and belongs to the father of a close friend of mine. When I pressed the power button, the HP splash screen with set up options appeared for a few seconds, then screen went black and would continue to cycle on and off like this indefinately. It would let me in to do all of the diagnostics, and all passed. It would NOT allow me into the F11 recovery section though. I finally grabbed my OEM W7 Pro disk from my desktop and inserted into the drive and did all the steps to install. I got the prompt that my Pro disk was 32 bit and incompatible with the pre-installed 64 bit Home Premium, but it did allow me to rewrite the boot sector, which is why it kept cycling on and off. I did have to enter the bios and reset to boot from a disk. I'm guessing that is what was missing. It now starts normally and boots directly into Windows.
I took out AVG, installed M$ Security Essentials, installed MalwareBytes, Spybot Search and Destroy, Spyware Blaster,and the Comodo Firewall... (in that order) all free and available from Download.com. Starting with M$ Sec. Ess. I ran the quick scan and it found a treasure chest full of viruses and bugs, and removed them. Continuing with all the rest of those programs (once again, in that order) I ran all of those scans and removed an incredible amount of junk that AVG let in. Additionally, the performance increased significantly.
Now, all is well, and I'm waiting for the maximum memory upgrad from Crucial to "ice the cake".
I hope this procedure helps anyone else with the same problem, if not, good luck with your machine.
