Strange. All your temperatures look good (under 35 C - that's great), and the SMART data for your drives looks good, so I don't see anything suspicious in the Speccy report. I see you have an Asus motherboard; did you get all your drivers from Asus? You could look in Device Manager to see if any entries have ! or ? next to them. You might also run Malwarebytes, get it up to date, then do a scan. After it runs, click Quarantine All and follow the onscreen instructions.
In addition to the above, let's download and run MiniToolBox from here:

List last 10 Event Viewer Errors
List Installed Programs
Post the resulting log here & let's see if your error log is showing any kind of problem we don't know about.
