Sounds like a hardware issue ... the first thing I would check is to see if you fans in the computer case are working properly
The fans are on, and I had HP reload all the software. They did a hardware test, and all was good. It worked perfect until I tried to upload photos. I don't know how to do a crash report. Seems like a Lightroom issue
It's almost certainly a hardware problem. There is no function in Lightroom that will restart the computer.
The fans are on,
Fans being "on" isn't really what I spoke of ... are they working properly?
Also, have you vaccuumed out the dust from your computer case recently?
no, we haven't vacuumed the fans. It only shuts off when we are uploading pictures, it can sit them on all day and never shut down
