So my recently built PC is having some weird issues.
After installing Windows 10 to the SSD and using the HDD as a storage device it began to freeze every 15 minutes or so. Only playing games though.
The first time this happened I had no choice but to hard reset. Getting back into my computer, everything ran extremely slow. All games ran at about 20 frames after usually getting 90.
I reinstalled Windows 10 to the SSD after cleaning out the SSD and HDD of apps and settings.
Now it's happening again, but the computer hasn't slowed down any. I'd like to fix this as soon as I can.

Do you have a special app to use while doing this? Or just use Task Manager?
