Worked like a charm. Any idea if going max could cause a system to power
off for any reason? Was watching a youtube video and suddenly the computer
just powered off. TV (plugged into same outlet) was still on. Since this is
the only thing I've changed in the last few days...and this is the first
time in 2 yrs that this has happened...I just wondered if it could have
overheated the system. Any log that would give me an idea and what would I
look for?
