Have an older HP Pavilion, rarely used but always seems to be working harder than it should have to when I do use it. I assumed it's just old and painfully slow.
It is connected to an external monitor which I switched off and just left it running assuming updates or system scan had the hard drive working for several hours offline.
Got fed up, turned on the monitor and there is video playing full screen. Hit escape to get out of full screen and the video just stops. No player running and hard drive still working.
Defender did not run a scan and neither did Avira. Not sure if it was defraging but still no explanation for the video playing.
Any ideas as to what's happening here would be appreciated.
Thanks in advance.
