Hello, guys! Inherited an old (late '06) MBP from a family member and the machine has seemed to work flawlessly since I got it, until I decided to do a boot camp install of win 7, so I could play som FO:NV.. When tried to play, the machine was laggy as hell, and when I ran win experience index I noticed the CPU was rated way below what it was supposed to. After some confusion I installed CPU-Z, where I noticed that the CPU was on the lowest throttle setting (977 MHz), even on full load. I have tried all kinds of chipset driver updates etc, as I thought it was a problem in Win 7 (which is unsupported on this machine), but on booting into OSX SL I noticed that its the same situation there. I have tried various apps, like CoolBook, to no avail. The CPU seems to be in good shape, as the temperatures are low and steady, and the stress tests all run well (although on lowest multiplier/voltage) Any ideas anyone? EDIT: And by the way: It also has a faulty battery, at under 150 cycles.. I guess it's too late for return...?
