Hi guys. A few days ago there was a power outburst for what i can think of and my computer stopped working (won't power up) . I realized soon that some components may be fried and I went to a computer service nearby where they told me that the PSU was dead. I changed the PSU and went back for more information after i noticed that replacing the power supply with a new one didn't change a thing. This time they said that the hard drive was fried and the motherboard is shutting the power to prevent further damage. Just to be sure i asked a friend to test if the hard drive was still working by installing it in his own computer but he experienced the same problem only this time after unplugging my hard drive from his SATA port , his computer started behaving like mine. It won't power up. He measured the voltage in some points and said that the hard drive was receiving current but the circuits from the main board connecting to the power switch weren't receiving any. Now i know my computer may have a fried motherboard and my hard drive could also be roast but what about his ? Can a faulty hard drive fry a motherboard ? Much obliged.
