OSX Corruption

Bit of an odd issue here. I was in my bootcamp win7 partition recently and had it shut down on me due to an overheating video card while gaming. This cause MacDrive to corrupt my OSX partition as it didn't unmount properly. The result of all this is that, while I can boot to OSX, it is incredibly slow in doing so. Going from spinning gear under the Apple icon, to bluescreen, to login screen takes about 15 minutes all told.

Once I actually boot it mostly appears to function normally however, albeit with two differences. The first is that it runs 15C hotter. I was curious about the temperature discrepancy, so I checked activity monitor and saw that kernel_task was eating up 100%+ of CPU. Second, I can't shut down or reboot without it going into kernel panic and causing OSX to alert me that there is a problem and I need to shut down.

Repairing permissions, repairing the disk, booting is safe mode, and running a full OnyX maintenance and clean routine has done nothing.

Running a 2008 MBP with 10.6.7. Any thoughts? I'd rather not backup and do a OSX reinstall if at all possible.

Much obliged, gentlemen.

 

Yeah, it's just a hassle.

Anyway, the saga continues: Backed up, attempted to reinstall (erase+install), both from the factory disks (Leopard) and the Snow Leopard disk. Both times it would get to around 90% and then give me an error message saying that the OSX partition could not be used as a startup disk. Welp.

Used disk utility to delete my Win7 partition, merge everything, and then format it. Attempted to install OSX. Same error message. Repairing either the disk or the permissions does nothing.

I assume a trip to the service center is in order, unless anyone has an alternate suggestion? This is all rather tedious.
