Tell more. There are some HP models that when you see this you clean the heatsinks, apply new heat sink compound as clean as you re-assemble and hope. You also don't issue any warranty on the work from the shop due to the disaster that is known for these models.
When ever Norton runs a full scan my HP laptop, Windows Vista gets hot and shuts down. I have a fan mat underneath my laptop and it still gets hot and shuts down. So now (only happens when Norton does the scan) How can I figure out what causes the problem and how to fix the problem?
