Hey guys, my son's P5Bdlx was fine 24/7 for a month playing online games and folding FAH at night, until wife turn it off the other night. In the morning it wont boot, no beep, no post, monitor blank, but fans running.

Read trough this thread and think it's CPU. Switched CPU from E6400 to E6600 still no beep no post.

Changed VGA card same.

Swap RAM still same. But without RAM shouts three beep so I think the mobo is responding hence not dead?

Clear cmos same. What else I can try? Help!!
