The computer restarts and I keep getting the same message.  I had a message on Sunday that said " critical process died". I tried reinstalling windows and doing backups but now all I get the message in the subject line.

Hi @Kerrycat,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here?

I see from the post that you are getting an error while installing. Don't worry as I have a few steps to help you get through this concern,

Let's start off by performing a Hard reset on the notebook: A power reset (or hard restart) clears all information from the computer's memory without erasing any personal data. Performing a power reset might fix conditions such as Windows not responding, a blank display, software freezing, the keyboard stops responding, or other external devices locking up.

Next thing, I would suggest here is to run the system diagnostics test as well as an extensive test on the hard drive and memory from F2(Please capture the failure ID for further assistance).

Depending on the test results, if all the test passes, I would suggest you perform a system recovery. Doing this will wipe off everything and set the computer back to the original factory conditions. So, please remember to back up your data before initiating system recovery. If for some reason the recovery fails. The only other way to install Windows would be to order the recovery media for your laptop and using the recovery media you can install Windows. You can check if the recovery media is available online on www.hp.com/drivers by entering the exact model no. of your laptop. To find the exact model no. click here: http://hp.care/2bygf7l

Otherwise, you could also reach HP phone support to order the recovery media. If your product is out of warranty, please choose paid options to get the tech support number.
