Please help,
My P4 titan motherboard with WD SATA will not power up with self powered usb devices plugged in (Memory stick, usb Hardrive, scanner etc)
There is no POST, no screen, no fan noise. It is as though the PC is not plugged in. (it is though, I checked!)
Have tried changing power supply and a PCI usb hub.
unplugging the problem device will allow the system to boot and plugging the devices in after system boots is fine with none of them exceeding the 500ma power limit.
Any help will be appreciated
Thanks
