Terri's computer is crashing multiple times and trying to reboot. Leo says it could be a myriad of issues including a flakey hard drive. That's the most likely culprit. It could also be a bad memory chip that is corrupted and causing it to load and stall. Maybe the stick has worked its way lose.
The problem is, if she brings it in, it'll get wiped and sometimes they can make it worse. She can try and run a recovery with Windows. She can also download Windows 10, put it on a USB key, and then select "Repair" when she runs the recovery. Then backup her data immediately.
