1.	Solve : Computer running, but no power to USB's or screen?
Answer» I am really flabberghasted by what's happend to my computer, for he life of me I just can't figure out what is wrong. When I turn it on, I can hear it RUNNING. But the monitor isn't getting any information. And the mouse's lights don't turn on. Also the computers green light around the button I push to start it isn't going on, wich seems wierd. Also strangely is the computer always has its little working light thing orange even when it is turned off. And also strangely the wireless interenet has a light that is on, so the that USB is getting some power somehow. It's all so wierd I don't even know where to start roubleshooting. I have 1.5 gigs of RAM, 2.1ghz processor, a 6800 Geforce OC, and a Soundblaster X-Fi sound card. My monitor is something Emachines gave me. I'm worried that some part or something has failed, as Emachines doesn't have the greatest reputation. If you guys need any more information, please ask away. I've tried googling and searching for answeres that might help with this.. but its a very hard problem to put into search TEARMS. So a FORUM was my best bet.

I am really flabberghasted by what's happend to my computer, for he life of me I just can't figure out what is wrong.

When I turn it on, I can hear it RUNNING. But the monitor isn't getting any information. And the mouse's lights don't turn on. Also the computers green light around the button I push to start it isn't going on, wich seems wierd. Also strangely is the computer always has its little working light thing orange even when it is turned off. And also strangely the wireless interenet has a light that is on, so the that USB is getting some power somehow.

It's all so wierd I don't even know where to start roubleshooting. I have 1.5 gigs of RAM, 2.1ghz processor, a 6800 Geforce OC, and a Soundblaster X-Fi sound card. My monitor is something Emachines gave me. I'm worried that some part or something has failed, as Emachines doesn't have the greatest reputation.
