Hi Guys, thanks for your input.
fouldsy: you're right. It's a desktop/workstation and not a laptop. Does this really matter or may contribute to the problem?
Yoda47: I guess you're not a Newbie

When i read your post, it really struck my mind to say "Why didn't I think of that!"
But heh people, thats the power of sharing and open-source, isn't it?
Wishing all a great weekend ahead. I'll be posting the result of disabling APM on BIOS to keep all updated.
