We have played angry birds on our pc for about a year- and having increasing problems with it and other games we don't use as much. After playing for a few minutes, it starts to lag really bad. Then even once you leave the game, the pc itself starts to lag (windows minimizing/maximizing) If I shut the computer down, then restart it goes away..until you try to play a game again. I deleted temporary files, did disk clean-up, and updated my nvidia driver. What could it be? It didn't used to do this. Please help I'm getting frustrated :/ HP pavilion 6GB RAM 64-bit OS number of processor cores: 4 hard disk- 931 GB C: 859 GB Free (921 total) D: 2 GB free (11 total) NVIDIA GeForce 9100 available graphics memory- 2943 MB Dedicated graphics memory-256 MB Dedicated system memory- 0 MB Shared system memory 2687 MB display adapter driver version 8.17.12.9610 monitor resolution- 1600x 900 DirectX 10

Well, no more help needed I guess- but to help anyone else who comes across this problem....tell them to clean out their tower! The main part of the tower was fine, but the housing where the fans are was really, embarrassingly bad. :facepalm: Cleaned it out and so far, so good!
