SpinNNN

Hey guys

I have this machine and the usb's don't work. i have 5v and I already checked the bios and it does not appear.. i Try to reprogram Bios but same problem. Can be a dead processor??

Any one can help me??

thank you

Check Dataline if fault on these lines then you have 99% CPU dead

Check the resistances on the lines -D, +D USB with GND.
