[techak2017]

i on my pc after 30 days and i start playing game suddenly i see game is freezing like hell(it was working fine before). its stuck for 3-5 sec evertime even my pc also freezing. If i open any programs i have to wait for like 3-5 sec ans then i saw in task manager disk usage 100.
i google it try everything like
disabled window search
disabled suprfetch service
uninstall antivirus
and many other things

but PC is still lagging.

my pc specs
core i3
4 gb ram
500gb hdd

What I would do is....go to Resource Monitor and look at your disk usage....sort by usage and see what app is using the disk so much.
