We had a thunderstorm that knocked the power out for about 1 minute. Now when we turn PC back on the green light comes on for about a minute then goes out. Fan does not come on, no POST, no sound at all from hard drive. It appears dead. I think motherboard was hit. It did have surge protector but I don’t know how good it is. I don’t have a PCI diagnostic card to test it. I don’t think its in Sleep mode, hitting key or mouse does not do anything either. How else can I determine if its the motherboard?
