Thank you in advance for your help on this topic. I have an HP 7000ZD laptop. Recently my laptop froze on me and had a RED line across the top of the screen. My computer felt hot so I thought it was overheating. I took a home fan and had it blasting air into the fans of the computer and it seem to work fine. However if I took the home Fan off the computer the laptop would freeze on me and with a RED line across the top of the screen. I took the laptop into an authorized HP Repair shop and the said I needed a new fan assembly on the laptop. I put the new fan in and the same problem still happen. But if I placed the home fan onto the computer it worked fine. So next HP told me I needed to replace my processor. I received the processor today and yet again same problem laptop would freeze on me and with a RED line across the top of the screen. I have reinstalled windows; I have ran the disk repair. And still the same problem. Can my Hard Disk being going bad? It seems like the last thing I haven’t replaced. Why can I have a Home fan blowing on the laptop and it works and if I don’t have a fan blowing into the laptop it freezes? Thank you again for anyone’s help on this. It’s mind blowing to me.

This is definitely an overheat, but if your internal fan is working fine I wonder what could be the problem.

Make sure you're not blocking any fan vents when you use it, or get one of those neat things for laptops to sit on that have integrated fans, I suppose.

I'm still really at a loss on why it would be suddenly overheating, unless it was dusty or something.

Thank you for trying...

Have you tried running a monitor program that shows all temperatures and fan speeds? That way, you can work out which component is overheating. I would suggest trying Motherboard Monitor (MBM) and seeing what it shows.
