I've got a strange problem: My comp shuts down when i play Counter Strike, Counter Strike: Condition Zero and Starcraft. When I play anything else it doesn't. My comp: MB - MSI K9N SLI Platinum nForce 570 SLI chipset Proc - Athlon X2 6000+ AM2 + Scythe Katana cooler Ram - 2x GeiL 512 MB 667 MHz AND 2x OCZ Specjal Ops 1 GB 800 MHz Graph - Asus 7900 GT TOP 256 MB Power - 450 Watt (I forgot the brand) Recently I changed the proc from AMD Athlon 64 3500+ and added the cooler. Thats when it began shutting down. I havent overclocked any components. Yesterday I opened the case and turned my pc on. I checked the temperature of all components and: proc: 37C graph: 39C Chipset: 66-70C !!! - I read somewhere that it's typical for nForce 500 series to work hot, but 70C?! Whats more, i made a processor stress test, it heated up to 50C, but the rest was fine and it didnt shut down. Can that^ be the cause??? Or maybe the Power Supply???
