Sounds like you got a virus.
Shut down and reboot. While rebooting hit the F8 key. Start Windows in "Safe mode with networking"
Down load and install Malwarebytes" and run it.
This works best if you sign into an account other than the one you use. If you have only one account on the PC then it's harder. You will probably have to run it from a flash drive.
(cough)..it doesn’t sound like a virus.
Forgetting that I am MCSE certified and one of Avast’s “evnagelists” on the Avast malware forums (and former virus technician for an AV company in Los Angeles), I highly doubt this is malware. I’ve had a couple of problems and Freeper OW did not even describe what she did previous to the shutdown.
Were there “link mis-directions”, pop ups etc? System restore, F8 or it could be worse..a motherbooard problem. If it were a battery problem, then remove and simply turn on without the battery. If it turns on but blank screen, it’s MOST probably the video card. More description when she turns on the pc/laptop is needed..
That happened just yesterday with DJ69’s computer??? Sounds identical to what is going on with mine. Thanks for the link ray
