Hey there, I've put about 190 hours in Skyrim so far and I've never had this problem before. Within 5 minutes of gameplay, my game will freeze for several seconds, the screen will turn black, then put me back in the game with a dramatically reduced frame rate, and mouse input is severely lagged, nothing I do seems to fix it except for a total restart of my computer, but that only fixes it temporarily, as it will happen again within the same time frame during every single attempt at playing. I have no doubt that this is a memory leak, but I don't know what to do... ...Cleanmem did NOT help at all. I have 1GB of VRAM and 4GB of RAM, and I have never had problems like this until last week. Please, if anyone has any helpful advice, I would greatly appreciate it.
