So I've been having a lot of sudden shutdowns lately. According to Windows, it's been an update each time. But it seems a bit strange to me to have five updates in two days, especially ones so close together. Also when turning my computer back on, it says "AMD NB Thermal Shutdown," which sounds a lot like an overheating problem to me. I was just cleaning out my fan in hopes that it would help when I noticed my video card has XFX Radeon HD 6870 written on it. Yet Windows and AMD both said that my video card is AMD HD 6700 Series.
What does this mean?
