I have a Windows 7 Acer Aspire x3475 with AMD Radeon HD 7000 + 7660D Dual Graphics (2343). When I play games, my computer freezes and the screen goes black. The only sound is a loud beep that does not stop when it freezes.
The AMD VISION Engine Control Centre shows that when I go into game - full screen or windowed mode - the Activity GPU watch and Memory watch skyrocket. When that happens, the temperature goes over 41 degrees (around 42-44° C), and the computer freezes. I have tried to decrease the MHz on the memory and GPU (as much as I can). It seems the PC works on low MHz, but after maybe 5-10 minutes the computer freezes again.
- I have tried Furmark Stress Test, but my PC just freezes too fast, so I don't get any results.
- I have dusted it.
What do I have to do?
