Check your bios/cmos settings (press DEL button while booting), and make sure no USB device is set to boot frome.
(some bios's recognise large USB's as harddisk's drives, and when booting it check's the drive boot sector, and hang, since no boot sector is located in it)
besides the beeps which indicate a motherboard timing issue. There should be LED blinking codes given on the front LEDs. I will include the blink codes below, but lets try to at least get the system up and running. First, I would like you to remove the RAM sticks from the laptop and just reseat one stick back in the machine. Try to boot with that one stick, if it does not, try the other alone. There have been issues when reseating the ram or re-installing it have temp. fixed the issue. If it does reboot, go to the HP support site, put in your model number of your laptop and download and install an updated BIOS. Below are the blink codes that may narrow down the problem.....

You will need to do more trouble shooting. If you can, boot into safe mode and see if system reboots. If it does boot into the bios and see if it reboots there.
If system reboots in all modes then you have a hardware problem and will need to be serviced. However if it does not reboot in the bios then there is a good chance that some part of your windows system is corrupted.
