First thing I would check is the power supply. Either use a tester or swap it out.

Sounds like your hard drive is no good. Only time I've ever gotten that error on a perfectly good computer was when I had a hard drive failure. I hope you have all of your data backed up. Since it's an HP I will assume that it came with a set of "System Restore Disks". Try doing a System Restore with those disks and see if the system starts working. If it doesn't magically start working... Well based on the fact that it's Windows Vista and an HP you may be better off buying a new computer than having it fixed professionally because I want to bet it's at least 4 years old?

Good luck.

The system disk is where your OS is installed.

Is the hard drive making any weird grinding noises or clicks?

Can you feel it spin up?

It sounds like it is POSTing so try resetting the defaults in the bios.

I would really check the power supply before I would invest in a new Hard drive.

That's not testing the PSU. You need to be sure it's outputting the correct voltages.

A bad drive wouldn't cause the on/off problem you were first referring to.

A bad power supply may cause the hard drive not to spin, therefore BIOS wont see it. A dead drive will do the same. If you have an old drive laying around, and its compatable, try swapping them out and see if your tower is still experiencing shut down issue. But if your running Vista, and its OEM (HP) might be time to purchase new computer.

The disk boot failure could come from a number of sources. A bad drive will also cause the system to turn on/off.
First, check your BIOS settings to see if S.M.A.R.T drive reporting is enabled. If it is, disable it and give it a test run of 2-3 days under a regular rebooting cycle to see if the error persists. S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a standard developed as an "early warning" system to detect hard disk issues. The SMART technology while useful under certain circumstances had an extremely wide margin of error and would throw errors on boot occasionally when there would be nothing from either a physical or configuration standpoint failing or pending failing in the drive.
While we're in the BIOS, I'd recommend that you ensure that it is recognizing the drive correctly on each startup. The easiest way to ensure this is to reset your BIOS default settings. While on the BIOS screen, look for an indication either along the top or bottom designated by one of the function keys (I believe it used to be F10 to restore defaults). Be sure to save your changes and exit. Again, where you did not get the error every time, you may need to monitor its progress to see if the error returns.
Second, physically check all cabling. A loose or in some cases failing IDE cable (assuming it is an IDE and not SATA connection) will produce these errors in the Pavilion line (and most others I would well imagine). Power everything completely down, remove the side of the case to give access to the drives and start with reseating the cable both at the drive end and the controller (where they plug into the motherboard) ends.
If the above suggestions cannot solve your issue and if your hp is more than 3 years old your hard drive may have lost its soul and you have to buy a new one. Formatting and/or recovering the drive will most likely not correct an error of this type.
