I've done a search for issue and found none.
I have a 2 Terabyte Seagate USB drive. When I try to boot with this USB drive connected to computer the POST hangs. Once I remove the USB drive the system boots as normal.
My system also has a USB RF Transceiver for the keyboard and mouse. It causes no problem though just the drive. Very frustrating.
All drivers are up to date.
Any ideas would be appreciated
