    Hi, i just registered to this site, and have a ?

    i have a ASUS M3N78 PRO M/B, was working fine and the other day i turned my comp. on and it said USB Over-current detected....shutdown in 15 sec, now it just doesnt turn on at all, i dont know much about the internals of a computer and would really appreciate help/advice. right now the comp doesnt turn on, the green indicator light on my M/B lights up when the power switch is on, but when i go to boot up the comp. my led fan lights flash and does nothing, and the green indicator goes dim.

    thanks in advance

    With system OFF, do the following;

    1 Disconnect any usb device; ie printer, scanner, hub, etc
    2 Clear RTC or cmos using the jumper. For detailed instructions regarding clearing RTC, read your manual.
    3 After replacing the clear jumper, power ON the system [all usb devices still disconnected]
    4 If you get a post display and the system boots, shutdown and start connecting devices one at a time until you find the failed usb device.
    5 If you do not get a display, it is either a failed pw supply or a failed mb. To test, swap in a known good pw supply.

    I assume you have not updated the bios and no new usb devices have been connected.
