While I play the Warcraft 3 custom map DotA, my computer will, periodically, freeze up. This freeze lasts typically around 5 to 10 seconds, during which I'm unable to control my computer. That is, I'm unable to move my cursor, alt-tab, bring up task manager, etc.
For the first few seconds of the freeze, music and BGM plays as normal, but, after a few seconds, it'll continually loop for the remainder of the freeze.
For the entire duration of the freeze, the visual remains frozen.
To others, it appears as if I'm lagging for the duration of the freeze.
After the freeze ends, what happened in around the last half of the duration of the freeze will "play" on my monitor extremely quickly.
This freezing doesn't occur outside of Warcraft 3.
This problem started appearing around 2 days ago. Before then, everything was fine. To my knowledge, no new hardware nor software was installed.
Updating my gfx driver hasn't stopped the freezing. My CPU temp averages around 51 C.
Thanks in advance for the help!
Dxdiag attached.
Edit: It's now happening in a different game, Rakion, as well. Just randomly freezes for seconds at a time, during which I appear to be removed the game as a whole to my friends, but then reappear when the freezing stops.
Does it have something to do with my internet connection?
