Ok, so before I say anything I'm going to give my specs.
AMD Phenom II x2 550(water cooled)
8GB(2GB sticks) of G Skill DDR2-1066.
Two 2TB hard drives
600W power supply
Nothing is overclocked and the Processor is not unlocked.
Now when I play any 3D game, I crash. It locks up and makes a "farting" sound. Now I've updated all the drivers for the GPU and the motherboard chipset, the sound drivers, everything. Still crashes. I've tried other games, everything from Mass Effect to Splinter Cell to League of Legends, Even Minecraft crashes. I can't figure out whats wrong. Any help would be very much appreciated.
Usually when you are using a high CPU/RAM intensive program, crashes are due to RAM voltage or setting not being optimal, or heat, or PSU not being able to deliver the current needed.
Check in the Event Viewer for Critical Errors, if running Win-7 use the Windows Memory Diagnostics to check your RAM, and check the BIOS to see if your RAM voltage is optimal and the settings meet the RAM specs.
Also the BIOS will give you temperatures of the CPU, and system points, and Voltages on each of the 3 channels, 3.3V, 5V , & 12V. On the GB board it' in System Health.
