I just want to throw my name in as also having this problem. And just to be clear, here are the symptoms:
- After a random amount of time, the entire system will hang-- internet pages won't load, UI will get stuck, games will lock up.
- A couple seconds later everything will stop responding. The only thing that still works is moving the mouse (but not clicking).
- The only solution is a hard restart.
I've tried changing the power settings, running the disk, memory, and system file checkers, I've adjusted memory usage, updated all available drivers... none of it has worked.
Microsoft needs to fix this this.
