Great ideas once again Dean. I have tried a couple of them already. The HD
and Graphics card are still fine. New PS checks out also. I may have
mis-wrote in my first post. The computer never GETS to post. I get nothing
but a black screen. The cpu and case fans run. No error beeps. I have left
the power on for up to ten minutes. No smoke or smell, I touched the ics
chips and they were cool. I just have two 2048 matching ram sticks and have
interchanged them a few times. I haven't pulled the cpu yet so I may try
that. I have replaced cpu's before and I think I got the paste on right but
who knows. It just acts like the mb is dead.
Thanks,
jimi
