I moved the internals from an Aerocool M40 case in to a Antec P150 case. Only thing changed apart from the case was the PSU (was a Seasonic but now swapped for a Antec NeoHE).
OS by the way is Win 7 Home Premium.
When the computer goes to sleep I can't get it to wake up. No matter how many times I press the on off button, the reset button, press keyboard keys, mouse buttons etc. I end up taking the side off, remove power cable to HD, then switching off the PSU.
Could it be the Antec PSU has a blip?
Had no issues in the Aerocool M40.
Thank you.
