GPU run very fast, Black screen and a hang noise on speaker
I have read all threads regarding gpu issues but nothing is the same with mine.
Here is the story. Whenever I boot my desktop, everything runs as it was expected to. I runs all low-graphics(idk the right term) such as ms word and regular browsing.
Here's the thing, whenever I run online game such as WOW and Heroes of Newerth or EVEN the assessment test (the one use to know the ratings of pc) the fans of the gpu runs faster for the first 5 sec and runs really fast for the next 5 sec. As the gpu makes noise, the display gets black my speaker gets noisy(Sound like it hangs). With this I am always forced to shutdown using the pc's power button.
PC specs:
MSI a55M-p33
Cooler master GX2 550w
GeForce GTX 550 Ti
APU a6-3500
4x1 gb corsair ram
750x1 HDD
160x1 HDD
In addition, I have just replaced the mobo a day ago from ecs a55f-m3 (taosted due to sudden shutdown) and everything is working fine (same parts) so with playing 3D games. Help me fixed this please!!
