Heh, I'm glad you got it fixed, but now that I've installed XP, I am having the same problems you are.
My cores are supposed to be 2.16GHz each, and now it's reading them as 0.96GHz. What exactly did you change in the BIOS to fix this?
Edit: And I don't have much for options in my BIOS. Alienware seems to have locked out almost everything except boot device priority.
Maybe I'll call the 24/7 tech support if I can't resolve this with some Google searching.
Edit 2: Well, that seemed to be simple enough. The fan button isn't actually something that turns the fan on, but it instead it reduces voltage, and underclocks the CPU, which then leads to longer battery life, and lower temps. I was always turning it on right after my computer booted into Windows, and then it was showing me the low CPU speed. Turning it off put my clocks speeds back to normal.
Hmm, whenever I'm installing something, or maybe switching between applications, or windows, my mouse seems to freeze for a second. I've installed the Windows Hotfix that addresses dual core computers. Anybody know what gives?
Although, I am noticing some system lag here and there. And I'm not sure what could be causing that. I read somewhere that you need to download and install a Windows hotfix to make Windows XP better compatible with dual core CPUs.
