today i downloaded a game called chess ultra. when i opened it the graphics was so high that the game started lagging. so i quit the game. but after this my pc was super slow. the cpu,ram,disk,gpu,network all are free (2-15% used) but i can't even search a program on start. i disabled all third party services and restarted. but nothing changed. i have also uninstalled the game. for a simple task to run like task manager it takes one minute to open. by the way i don't have a graphics card.
