For some time I had problems with StarCraft in Windows 7, after playing for 20-30min Windows 7 completely freezes keyboard, mouse and video (background programs and even Skype still work, but a hard reset was always the only way to get out of it). Since I was not playing much (just a few games a week) and it did not happen to me that much, I did not worry at first. But after starting to play ICCUP a few weeks ago with some friends, it just got annoying when I was crashing every 2-3 games. At first I was thinking maybe I overclocked way too much with my 4 Ghz, so I tried playing with normal 2.6 Ghz, but that did not make any difference. I also removed one of my graphic cards and tried playing on my primary screen instead of my third one. Nothing did help. It seems when closing all programs and making sure StarCraft only ran on one core (using the processor affinity setting in the task manager) the crashes occured less often, but I could not really fix this issue.
