Laptop working incredibly slow
I bought a brand new Asus laptop from save on laptops and it was working perfectly for about 2 weeks. I have installed numerous games and an antivirus called total av but even after these it was always running fine. I have made no changes recently and barely any browsing however while playing football manager, after about 30 mins of play the laptop froze for perhaps a minute before seemingly working normally again.
Now it seems to intermittently go very slow and unresponsive. I get maybe 10 seconds of it being ok before it freezes and it is unusable and this is from the moment it boots up now. I have run a virus scan, the hard drives have plenty of free space, have run defragment software, disk clean-up etc and everything is fine. I have checked task manager and there seem to be no processes using lots of resources so I am a bit stuck
The laptop is almost unusable making things like a system restore very difficult to execute
