it is either a bad ground... assuming you have no surge protector, just have the computer plugged directly into the outlet, or it is gremlins in the tower humming along.

Invest in a nice surge protector.

Its due to the Power Saver option being active. You can change the settings from Start>Control Panel>Power Options.

It sounds like your USB ports got blown out. Go to Control Panel,System, Hardware, Device Manager, scroll down to bottom and see if they are malfunctioning there. Check them all. If you can find even one working you can go buy a hub and save yourself a bunch of repair money.

Try going into the Control Panel, and selecting Power Management.  There might be an option in there to change what the computer does when the "lid" is closed.

it doesn't seem normal.  I always unplug my computer during lightening storms and never have any problems.

Did you try to look over your power options? You might have accidently clicked something to save yourself energy. Try: Start, control panel, performance & maintanence, power options. hope this helps :)

If the ethernet switch requires DC, then yes its a problem. You didnt specify.

It could be several things. Without troubleshooting it in person, it's hard to tell. Was there a storm? If so, lightening may have come in on it, even if you have it plugged into a surge protector. The surge protector may be faulty. It could be any one of the components in your computer. From the very expensive processor to a cheap modem card.

Plug all your computer equipment into a surge protective power bar...although very rare...it is known to happen\n\nBut to keep your system running should the power go out...install a generator to your power fuse panel.
