Hello guys,

My computer has been working normally. But last evening, when I booted it do my translation work, it suddenly crashed and the shut down automatically. Then I pressed the power key on the case, but there was no response. And the screen was black. I have checked the power supply. It was supplying power to the motherboard efficiently.Then I have no idea what should I do. In addition, the operating system of my computer is Windows 8 beta.

Pls advise!

Thanks a lot!
