I have a satellite that I've been playing WoW on for some time now. A few months ago it completely stopped working and would make this "metal ball dropping" sound, which I assumed was the HD failing. A few days later it was working fine, though it was saying I had a media failure, but started up an ran. Last night while playing WoW it crashed completely and when I power on, the fan starts, then it clicks and powers off. Absolutely nothing happens. I assume the motherboard is bad? Or could the HD cause this? I've already ordered a new laptop, but was hoping I could salvage this one. Thanks for any advice!
