Hi i have a custom built pc using an Athlon 64 3200+with stock HSF, an Abit Kv8 Max3 mobo, and a Radeon 9800 pro with stock HSF. i play counter strike source using this pc and randomly it freezes on me. it doesnt shut down so i ruled out the system overheating but the pc just freezes and i have to restart the computer. my guesses are the video card is not cooling or maybe the cpu is not cooling good enough. PLEASE HELP!!!
