I have a problem with my computer. So yesterday, my windows 10 started taking 10-15 minutes to boot. And once it booted, it would randomly freeze. So then I tried installing windows 7 in its place, and it boots fine, but the computer can barely handle basic tasks. For example, creating a new tab in firefox will make it not respond for a minute or two. Right clicking the desktop will freeze it, and even while i'm typing this it randomly stops responding. Can anyone help me please. Also, whenever this happens the cpu is only at 8% and the memory is only at 44-50% so it doesn't make any sense. Thanks
