Hi

Have you solved your problem yet?

I'm having the same problem. Works fine til shutdown, then won't boot (it doesn't even show the progress bar). Just stays black,

My mobo is an Asus P5GC-MX/1333, with an Intel C2D E8400 and 2 1GB Kingston DDR2/667.
Completelly different combination for the same insanity...

I've thought about never shutting down, but...

hi sorry to hear u hv the same problem as me
