Warcraft is freezing on me, anyone one else. And Why???
This is a common problem when hardware starts to fail and I would look there first.
If the entire system locks up/freezes then that is usually a sign of hardware instability or a driver problem. If just WC3 freezes (OS remains responsive) then check memory usage and other resource usage in case your system is hitting a limit. Note that some custom maps can just freeze Warcraft III (not the OS) due to errors made by the custom map’s author or bugs they encountered.
