This chip is an instrument of Satan put on this earth to make me insane.
I cleaned everything very thoroughly, both pins & socket. It booted up and ran fine for 7 hrs. including heavy loading from audio recording software.......problem solved? Not a chance. It shut off and now continues its quirky inconsistencies. Shuts down immediately, or boots through window and runs for 5,10 mins, 1-5 hrs then shuts off.
Is there a diagnostic utility that could be used when it is running to look at voltage, etc? Clearly the mobo, socket, & all else is well if it runs great sometimes. Can there be a fault within the chip or 1 of the 464 pins?
