Hey guys, I just recently got a old 2008 HP Pavillion M9500y. It's not in the best condition, I had to replace the Hard Drive with a PNY 128GB SSD. Before it was given to me it was damaged during a storm and the Windows Vista installation broke, I have installed Windows 7 Ultimate onto the computer. When turning the computer on there is a loud clicking sound, I think it is coming from the heat sink but I am not sure. I don't know if the heat sink is original, it's a Cooler Master one. The mother board idles at 100C, I'm not sure why. Any and all help would be appreciated.
