Hm. That sounds like it could potentially be an overheating issue. Does the system have enough room to breath?
Alternatively, it is possible that something wasn't quite installed fully yet. I'm noticing that it's becoming pretty common for things to install in the "background" while the system is being used actively for other things (like actually playing the game that's being installed
). While it technically does "work"...at times...it's very unsound reasoning. Doing so actually requires a LOT of system resources to be available, and it's very likely that a console (and most PCs) will not be able to complete the process without needing to suspend it. Suspending an installation process is not a "good thing". In general, I'd leave the system completely unused while anything is installing. (No idea if this even applies to your situation; just throwing it out there.)
