Some time ago (about 2 months) my computer started to freeze randomly (Window 8.1) and after a while (about 5-30sec) it runs again like nothing happened. I suspect the computer is waiting for some IO data (maybe from the ssd) because when it "freezes" I can still move the mouse and some windows still work (can interact with them) but most actions stop for example chrome lets me open new tabs, but won't load pages while "frozen". Some Applications stop responding (I think the do IO stuff in gui thread) but Apps that don't access the ssd drive work just fine while frozen (for example calc.exe)
That said, which tools or options do I have to find out what exactly is causing those random freezes. Eventlog shows nothing suspious sometimes some Applications log infos about the fact that something took very long, but no details.
Thanks in advance.
