Just noticed my PC has been running slower recently and games have been crashing with low fps. Checked my task manager and noticed my disk usage at 100% with Origin being the main offender running at 2.5Mb/s and every now and then "Service host/local system" using 5Mb/s.

I tried disabling windows search and supefetch but that didn't help.

My CPU currently at 12%, memory at 65% and network at 11%.

Any ideas?

btw I'm on windows 10

 
Solution
Launch resource monitor, select disk tab then click on total to sort by processes reading/writing the most to find out what process is the cause.
I suspect it could be your antivirus or Windows Updates causing the disk I/O.
