It shut down by itself after about 60 minutes on

Check your power settings in the control panel. More than likely, it is set to "go to sleep" after 60 minutes.

Observe if the processor cooling fan is spinning that cools your processor. Or your unit need cleaning where the vents of your laptop is clogged with dust and the cooling system will be affected that made your system shutdown automatically

My compaq presario cq42, frequently heating more than normal heat. Some time it suddently turn off by it self , before that it show some BIOS page.

Glad to HELP YOU!

If your machine is OVERHEATING that means it's a SERIOUS PROBLEM with your fan.
Open your laptop (ONLY IF THE WARRANTY IS EXPIRED!; if not go check your dealer for this procedure) and clean a little bit the fan. Almost sure the rotor is full of dust.
If the problem will persist after you will do that and you will re-assemble your machine - then REPLACE THE FAN!
Your computer is turning off because the sensors detect a too high temperature. So to protect your motherboard and all your circuits and devices it turns off. It's normal under such conditions.
But if you will continue to use it that way (overheated) you risk to damage it!

I just bought Compaq Presario CQ42 which black in color (i don't know the model exactly). i have a problem with the touchpad. i want to lock it but i didn't find the button and i don't know how to lock or...

Underneath the Laptop is a Users Label marked Model it should give the FULL model No. - e.g. Presario CQ42-100 - HP made something like 150 different models for the Presario CQ42 !!! so you can see, I'm going to have to guess about this...
If your Touchpad has a black(?) dot in the top left corner - tap this once to turn the Touchpad off while you are typing.
Touch it again, to turn it back on.
Other Presarios' have a switch nearby to do this...
