PG Value is the time, in milliseconds, from turning on the PSU to when the voltage is actually sent. A high level would indicate that it is taking too long for the PSU to power up. Really looks like the PSU is dying to me. Might be worth checking with a friend to see if you can verify with a swap. Good luck!
Thanks for your help. I wasn't sure what the PG value was referring to. I'll swap it out and worst case scenario, i'll RMA the PSU.
Thank's for your input.
