I have an Inspiron 3583, and every once in a while, usually while on FireFox, the computer will just randomly freeze (no response from mouse or keyboard) for several seconds, then return back to normal as if nothing happened. No BSOD's, no restarts, just annoying brief freezes that last for several seconds. Diagnostics report that everything is OK. Doesn't seem to be a Windows 10 issue as my last laptop never experienced this issue. The only thing I can think of is some sort of driver issue or a Dell application running in the background. Any suggestions?
