I have a Mac Pro 1,1, with 2 Xeon 3.0 ghz processors.
On a recent power up, it gave me the dreaded blinking folder with question mark. However, none of the typical methods of dealing with this have worked. Cmd + R does nothing, cannot connect to internet so Shift is useless, and holding Option after chime brings up the HDD and Recovery partition, but when I click to choose eirher, the icons disappear and the computer hangs up. I tried with a bootable USB with identical results. I’ve reset PRAM and SMC with no fix. I even tried an entirely different logic board in the system with the same results.
Does this indicate a problem in another component? Could a faulty PSU do this? What other internal components could cause this error?
Any help is greatly appreciated.
