Hello out there @ bleeping computer.
My laptop has a problem were it will just shut down and not start up again for a while. It had this problem last year and I sent it in for service. Then I got a chill pad for it, but it still acted up and I had to call HP for tech support. They walked me through it, but now my warranty is over, and I need some professional help. The other day it would lite up, but a black screen. My daughter finally pulled the battery, and at least the screen came back, but it cuts off on me at least 2 times a day now. Help

The symptoms you describe could be symptomatic of a variety of things to include hardware/software issues, overheating caused by a failed processor fan, bad memory (RAM), failing or underpowered power supply, CPU overheating, motherboard, video card, faulty or unsigned device drivers, CMOS battery going bad, BIOS and firmware problems, dirty hardware components, programs hanging or unresponsive in the background, and even malware. If the computer is overheating, it usually begins to shutdown/restart on a more regular basis. If you're not finding any malware then its sounds like one of the latter problems.

When was the last time you cleaned the inside of your computer? Dust restricts the airflow and prevents proper cooling. This in turn can cause overheating and faulty processor fans which can result in unexpected shutdowns, random restarts, booting problems, etc. If you use a notebook, they get dirty too and need to be cleaned.
  • Clean out the vents on the computer with a can of compressed air to ensure that they are not clogged with dust.
  • Unplug the computer, open the case and clean out any dust and debris you find inside. Be careful not to aim the compressed air directly at the circuit board or electronic components.
  • Check all the electrical connections and make sure the fans are all operational.
  • Remove the cards and RAM modules, clean the contacts and reseat them.
  • Check the heat sink on the processor to ensure it is not blocked with dust or debris.
  • Remove the CPU's cooling unit and clean the fins on the heat sink that sits under the CPU with a can of
    compressed air.
  • Feel the CPU heatsink when it powers down. It should be warm to very warm but not hot.
  • Inspect the thermal compound between the CPU and heat sink as it can deteriorate over time so. You may need to remove it, scrape away the old thermal gel that makes contact with the processor, then apply a very thin coat of fresh thermal gel on the surface and fit the heat sink back in place again.
  • Monitor the temperature of your CPU, motherboard, hard disks, voltages, and fan speeds.
How to Clean a Computer Tutorials with Screeshots:Note: Some video cards can generate such intense heat while playing games with high quality graphics that they require a separate cooling system. If the fan fails after wear and tear with age, the video processor will not be far behind and your system may start crashing.. If the video card needs replacing, see "Illustrated How to Replace an AGP Video Card".

When Windows XP detects a problem from which it cannot recover, it displays Stop Error Messages which contain specific information that can help diagnose and resolve the problem detected by the Windows kernel. An error message can be related to a broad number of problems such as driver conflicts, hardware issues, read/write errors, and software malfunctions and malware. In Windows XP, the default setting is for the computer to reboot automatically when a fatal error or crash occurs. You may not see the error code because the computer reboots too fast.

An easier alternative is to turn off the automatic reboot feature so you can actually see the error code/STOP Message when it happens - this is also known as the Blue Screen Of Death (BSOD). To change the recovery settings and Disable Automatic Rebooting, go to Start > Run and type: sysdm.cpl
Click Ok or just press WINKEY + Pause/Break keys to bring up System Properties.
  • Go to the Advanced tab and under "Startup and Recovery", click on the "Settings" button and go to "System failure".
  • Make sure "Write an event to the system log" is checked and that "Automatically restart" is unchecked.
  • Click "OK" and reboot for the changes to take effect.
Vista users can refer to these instructions: How To Disable the Automatic Restart on System Failure in Windows Vista.

Doing this won't cure your problem but instead of crashing and restarting you will get a blue diagnostic screen with an error code and other information to include file(s) that may be involved which will allow you to better trace your problem. Write down the full error code and the names of any files/drivers listed, then provide that information in your next reply so we can assist you with investigating the cause.

Thank you,
But it's just what I was afraid of, a service trip for my laptop. I will follow your advice until that is absolutely necessary.

Not a problem. If you obtain any info after a BSOD, you can post it back here and we will try to help you investigate it.
