Ok so one night I was playing games and then my games start randomly crashing saying I don't have enough memory to run them. I have run these games in the past with no problems at all and my RAM had been completely normal. I close the game I was playing and open up Task Manager, and it says over 50% of my memory is being used. The largest application I had open was Discord which took up nowhere near 50% of my ram. I have 8 gigs of ram and I use Windows 10 operating system. Does anyone know what might be causing this? I am afraid it might be malware but my antivirus software "Webroot" has not detected anything after numerous scans and I have no idea where I would've gotten Malware.
