for last one month, i'm facing a huge problem. Its like that - i switch on ups, then switch on CPU, monitor is showing Acer and then my computer stops. Its not happening always. And from last week my speakers are not working. On control panel no devices are showing. But the speakers are working with other computers. Please help me.

Is seems to have issue on the motherboard and i think you need to go through your issue with the technician or manufacturer where you bought the system. as you said that your speaker working with the other computer and i think there must be some fault on the motherboard and therefore make sure your motherboard audio device working properly.
