[Riptide]

Hello all,

My grandfather recently got a custom built computer from a friend of his. It looks really nice with a see through case that has a bright blue LED light on it.

However, the computer spontaneously shuts down when the printer USB cord is connected to one of the ports. From what I have read I suspect that a faulty power supply may be the cause. It would make sense to me since the blue light must already draw a great deal of power from the computer and the computer only shuts off when another USB device is attached. However, I would like to hear everyone's opinions anyway before I run out and buy anything.

Also, a 'USB overloaded' message apparently used to pop up too when the printer was attached. This would be a problem with the power supply too right? And if the USB is ever overloaded is it damaged?

I apologize if the answer here is obvious but I'm still new to installing computer hardware and the like and I want to be cautious.

the two probable culprits that come to mind would be an underpowered/damaged PSU...or a faulty USB port (or possibly misconnected)..

if you're plugging the printer into a front USB port or some other extra usb port that's not directly attached to the motherboard (i.e. soldered to it) then the guy could have screwed up the wiring on the USB pin header and gotten something backwards which would in effect create a short circuit across the USB header...which isn't a great thing

Thank you so much for the prompt reply! Unfortunately, I found out I won't be able to get back to my grandfather's right away but once I get there I'll try that out.

The printer was attached to one of the front USBs. I really hope there were no wiring problems as I don't think I can fix that by myself. Next time I can get over there I'll be sure to test out the other ports just in case.

as a side note...ALWAYS plug in "permanent"/essential USB equipment into the rear ON BOARD USB ports (by permanent i mean anything that is unlikely to get removed frequently)...they are the most stable and offer the most accurate power source...

IF the front ports wiring is messed up...you'd need to have the manual for the motherboard to confirm the proper pin out
