Computer shuts down unexpectedly

Product Name: Pavillion 500 326-na Desktop
Operating System: Microsoft Windows 10 (64-bit)

My computer frequently and unexpectedly powers down with a critical error Event 41 kernel power. There is no warning or other screen, it just restarts.


I bought a new power supply hoping  that woudl help but it didn't


I note with some surprise that HP computers/laptops have been suffering from unexpected shutdowns for several years. Has anything been resolved and with so many complaints why not?

Re: Computer shuts down unexpectedly

The first thing that you should do is, open the case and do a thorough cleaning.  Dust can cause the computer to overheat and cause the symptoms that you are experiencing.  I have found that this is the problem many times.

[ Edited ]

I'm sorry but this doesn't help. I have already replaced the power supply so have opened it up and have checked the fans are working an all the obvious stuff. If you check this website this seems a common problem with a wide range of HP computers going back to 2009. 


Thanks for trying. is there further suggestions please? I would appreciate any help
