Guidelines in a motherboard hardware
Should I buy a new motherboard or not. My computer kept restarting after every 3mins to four hours I returned my motherboard to the suppliers I installed it with some guidelines from a friend who is well versed with computers but the problem now my sound system is not working tried doing some settings using the control pane to reset the sound and increase the volume but still my speakers could not have sound.
My speakers are well connected to the hole at the back and when I put the on I can feel they are responding as they produce a funny sound.
What could be the problem please help
