My System Specs


According to that screenshot you posted your graphics card is overclocked. I see 700 GPU clock on your slider bar, and the spec sheet for the Radeon 4860 ATI Mobility Radeon™ HD 4830 / HD 4860 Graphics - Overview says it should only run at 650 MHz. Maybe you can post the exact model number of your GPU, so we can see if it's supposed to run at that speed?

To test if your issue is GPU heat (or power supply failing under GPU loads), make sure the "Enable ATI Overdrive" box is UNCHECKED, and run Furmark FurMark: Graphics Card Stability and Stress Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

The operating system can affect how much power a system draws (e.g. see the difference between laptop battery life on Windows XP vs Vista / 7), but Windows 7 should have similar or smaller power consumption.
