You could have an overheating problemWhen the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

My computer continues to shut-down for no apparent reason while booting up. It will get to bios then abruptly shutdown. Please Help!!

Maybe something is defective from the factory? Can you bring it back and exchange it for another? Is it a desktop or a laptop? If it's a desktop, maybe remove a side panel and aim a small fan at the inside. Do you know how to start up your computer in safe mode? Maybe try starting it in safe mode and see if you can do a system restore, do you know what that is and how to do it? Google will explain it to you, but I'd suggest those steps.

Compaq notebook won't boot up

Hi

When you boot the computer back up go into Safe Mode and check to see if you can roll the computer back to the point before you installed the software.

If so this should work. If it works then run a virus scan, a defrag of the hard drive and cleans the temp files.

OR

You can do a diagnostic startup and uninstall Onecare. So once that it is uninstall ed it should be smooth sailing.

Here is a link for some startup / diagnostic software you could try after booting.

I hope this helps
