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.It is most likely your Laptop is overheating. Has this problem always happened or is it recent?

I would try to get the money back for the new processor as it didn't fix your problem.It started a week ago. The fans where dirty before I replaced them a week ago. Can it be the hard drive overheating making the computer freeze? Thank youIt wouldn't necessarily be the Hard Drive. The computer should have an automatic shutdown sequence that will forcefully shut down the computer when overheating.

I suggest downloading Speed Fan and tell us what the temperatures are.Win9x:NO  64Bit:NO  GiveIO:YES  SpeedFan:YES

Thank you for helping me!As soon as I got done posting that my computer shut off with a blue screen. I didn't have the home fan blowing on it so the speed fan would get the correct readings. As soon as I put the Home fan back on it it works fine again its crazy.Actually I meant these RESULTS:
When I had my home fan on the laptop it read like this
HDO: (With a down Arrow) 34C
Temp 1: (With a down Arrow) 30C

When I turned off the home fan it read like this
HDO: (With a check mark) 35C
Temp 1: (With a down Arrow) 30C

3 Minutes after I had turned off the home fan it read like this
HDO: (With a check mark) 36C
Temp 1: (With a down Arrow) 33C

And Then it shut down and rebooted

Thanks36*C is pretty low for the computer to respond to the heat but it seems that way...

Can you try a SYSTEM Restore to a date before this problem?I did restore the computer before an earlier date. That did not work So I reformatted the computer from scratch and that did not work...Hmmm....do you think it's possible there is a problem with the MONITOR, not the computer itself?

If you have another monitor laying around, try plugging it in the VGA port and see if the computer freezes.I can try that at work tomorrow if I boot up with another monitor will my laptop screen be on at the same time? If this works with another monitor can my laptop monitor be fixed? Thank youIf it's a simple Driver problem, you just have to reinstall the drivers.
If it's a problem with the monitor itself.....
