Have a Compaq Presario V2000 series notebook (bought between 2004 and 2005)?
Is it automatically shutting down for no reason after maybe 30 minutes to 1 hour of use?
Then the problem with your notebook (like mine) is that it is overheating.
How can you tell if its overheating and not some other problem like a virus?
Go download and run the CPU Burn In program. It is a software that runs your CPU to the maximum possible operating temperature.
I set the program to run for 5 minutes and within 2 minutes the notebook shut down by itself. The reason is that Windows automatically shuts down to prevent any thermal damage to your CPU.
I contacted the HP technical support (text chat with a technican, a phone call support would cost money, $30 I think) and they said that since the notebook isn't under warranty anymore I would have to pay $259 to sent it for an inspection.
Seemed like a rip off to me and after I searched around, I saw a post in the forum with people having the same problem as me. They said the reason why the notebook overheats is because there isn't any thermal paste between the CPU and heatsink!
Look at the picture below:
