I logged in to my iMac today running leopard and one core is maxed out at 100% CPU. My keyboard will not connect and it everything just keeps hanging. I have tried removing everything from the login items menu but nothing is working. I booting in to Windows just to make sure that it wasn't a hardware issue and everything seems to be ok. The only real change before this problem ocurred was that I installed something in Windows that reduced the size of the windows partition to just 4GB. Could this ne the problem? I can't even launch console in normal boot up. I can launch console in safe mode but it doesn't tell me much. Has anyone got any ideas? Please help.
