Isn't the sata ports because it won't boot usb devices either.
Could be the chipset, this handles all bus communications I'm guessing?
If only there was a way to isolate whether it's the motherboard or the CPU though - that'd be useful
Ah I see, in this case would a PCI usb hub be a suitable way of testing my usb drives to see if they would boot?
And if so, I'm guessing no boot = cpu problem, boot = motherboard?
I ask because I have one lying around and would rather avoid wasting money on a cpu and sata controller which will never see further use.
Thanks
