If you really removed the fan from the heatsink it's no wonder if it overheats. Games require more power and therefore the GPU generates more heat so it overheats much faster while gaming than with desktop usage. The fan is there for a reason. Sure you could try the general tip of reinstalling the drivers but I believe the heat is causing your problems in this case. If you can acquire another card somewhere plug it in and see if there's any change.
