My laptop gets really hot and the screen flickers on and off

[makeba]

My laptop overheats and cuts off. Sometimes the screen flickers on and off and it's frustrating to work on it when in does this. It goes back to the sign in screen every time. I think my fan has stopped working. can you help with this?

When the laptop starts getting hot, you should easily be able to hear the fain spinning up to cool it down. If you don't hear the fan, I suspect that it actually is NOT running -- and that is a serious issue as your PC will overheat almost immediately and shut down as a result.

That being the case, you need to get the fan replaced and such repairs can be very difficult and risky to perform, depending on how much stuff has to be removed in order to get to the fan to replace it.

For such repair estimates, you would need to contact an HP Repair or Service Center.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
