power surge on hub port one of the usb port has exceeded its power limits

hi,
actually i have a sony vaio vgn-sz330p notebook having windows xp sp 2........ and i m having an error power surge on hub port..... due to it my pc won't turn off by itself....untill i have to disable the usb port......by which my camera also disabled..... so tell me if u have any solution.....moreover my system becomes too hot...

 

It sounds like you have a camera that gets its power from the usb port and it is pulling more than the port is rated for. The camera may have some problem that is causing it to draw excess current. Try running without the camera for a while to see if that stops the error messages.

If the system still gets too hot, try blowing some compressed air backwards through it to clean out any dust and lint that may have accumulated.

 

yes it stops the error message..........but it doesn't stop the strange sound comes out ov my system............its like an high sound of fan......and this problem also effecting my system's performance

 

That would explain why the system is running hot. You have some problem with the cooling fan. Either it has an obstruction or the bearing is failing. Better get it looked at before it causes greater damage from overheating.

Many CPUs shut their speed down when they overheat. Others just go ahead and fry themselves. Be glad yours is the former type.
