I noticed the other day that my computer had rebooted. I thought nothing of it because sometimes it does that when it runs Windows updates. Today, my laptop was running on battery and I heard it make the noise that it was running out of juice and shutting off. I came back to my desk and plugged in the power supply and fired it back up. Then it was running slowly and started shutting off for no reason right in the middle my doing work. It started and stopped sometimes 3 or 4 times in one minute, but then finally started up and stayed powered up for a few minutes to 15 minutes. I tried running malware bytes on it and it quit in the middle because the computer crashed. I finally got Windows defender to do a quick scan with nothing found and same for malware bytes, nothing found.
Any suggestions? It sounds like MAYBE some type of hardware problem. I do NOT believe it can be an overheating problem because I keep a fan on next to the vent/cooling slots.
PLEASE HELP!!! Can't get ANYTHING done like this.
