Re: Boot problems
I second kmote's thought. Try hooking up an external monitor to see if it is your screen that's not working.
Since it is doing this over and over, it may be blue screening on you (the external monitor will show you in case your screen is dead).
It is also possible that another part has died on you. The cheapest to replace would be the RAM, followed by the hard drive and then the CPU. That's about all that can be replaced on the laptop (outside of the motherboard). I am not advocating that you just start replacing parts willy-nilly. Since HP/Compaq does not publish a list of what the beep codes are for their lappys (that I can find), these would be the order of parts that would have to be tested.
I would start by removing the RAM from the laptop and trying to boot it. If it does the same thing, you have a lead. Replace the RAM and remove the hard drive and try to boot. Between the two of these you should have a better inkling of what might be going on. Post back the results of these two tests, as well as what (if anything) hooking up and external monitor shows.
