On a semi-frequent basis--not constant, but consistent enough to be a bother--my computer freezes up, and I can move only my mouse. This lasts about 5-10 seconds, and then everything returns to normal. It doesn't matter whether I'm browsing the internet, watching a video, or playing a game, this happens, and there appears to be nothing I can do about it. My computer never used to do this, it's only begun within the last month or two. This is particularly annoying when it occurs during games...it's not limited to just the high-resource, more recent games either; it occurs during the extremely easy-to-run, low-maintenance 2000 game Deus Ex. But, I stress, it doesn't occur exclusively during games, and it is not ameliorated by changing any settings within the game itself. Furthermore, this never used to happen.
Things I have tried:
Updating my video drivers
Updating my sound drivers
Running Malwarebytes and SuperAntiSpyware scans
Doing a disk cleanup
Changing all relevant settings within games (it occurs outside of games though too, I have to stress this)
Checking processor temperature (it happens when the comp is cool as well as when it's hot; usually, it's in between 40 C and 60 C)
Any help would be enormously appreciated.
