This was a solution for me, i pulled the hard drive out and cleaned the connectiions to the mother board. HP in thier genius decided to create slot in connection for the drive ( like whats wrong with the normal connections type ?) anyway, open the hard drive cover pull the little black tab ( yes thats what removes it ) and blow the **** out of the hard drive connectors on the board and the drive. mine worked, hope your does. sorry to hear about the guy that cant boot from a CD, this isnt goign to help you :(. it worked for mine

Re: my HP Pavilion tx 100z won't turn on
It is not real hard to put in a new mobo but read the manual CAREFULLY make sure all the jumpers are set correctly. It sounds like bvrom's hdd is going out if not out already. HDD failure means it cannot read your hard drive. If you haven't already back up your drive if it will start and install a new one then install windows again

Does it make a beeping sound when you turn it on? If it does try this:
Turn it off and take the battery out for about 2 minutes. Put the battery back in and press the power button to turn on. Immediately tap the F8 key on your keyboard. This will bring you to the advanced boot options. Choose last known good configuration.
If that doesn't work you may also try choosing system restore in the advanced boot options and follow the instructions. Note that a system restore brings the computer setting back to a previous restore point.
I hope this helps.
The volume slider on your laptop is failing or having problems, I have had this issue my self it is usually caused by dirt and grime, so you may want to give it a good cleaning or residual heat from the processor. I'm posting the link to an hp support thread below, with several other fixes not mentioned here. I hope I could Help.
lights are on but nobody is home. This is a problem seen in a couple of HP model lines (dv, and tx). Short version... Your motherboard is shot, I hope you are still under warranty as HP hasn't owned up to the design flaw that causes the problem enough to do a recall or offer replacement.
IF you have critical files that you need to get from the machine you may try the following, however this is not a long term solution...
1) turn pc on (lights are on fans are running, no hp spalsh screen, no nothing) 2) put pc in a bag (what ever you would carry your laptop around in should work, or wrap in a towel, the point is that it gets really hot) 3) wait 20-30 min. 4) turn pc completely off (hold power button for several sec or unplug and remove battery) 5) try rebooting (you may have to try a couple times, and I have a superstition that holding down F10 while powering on helps, once you see the HP splash you should be good to go) 6) Remember that HP makes devices with all kinds of cool features, but they almost always fail shortly after the end of thier warranty.
If the system turn on and off and again on automatically, sometimes the problem is in GMCH. ie in the graphic chip. There are other reasons also. You have nothing to do unless you are a chip level technician. Contact me if you are. Make a reply for this because I will get satisfaction by it.
