BleepingComputer.com: Low Benchmark Scores Phenom 9600 4GBRAM

Hi!
I've been struggling with my low bMark scores:

WinRAR 454 w/TLB fix diabled Avg scores for my system ~1,100
Call Juarez 30 FPS Avg score = 45

I suspect I have a dead core (or 2!) Any way to check for a dead core?

Thanks, John

I wouldn't think you would have a dead core. You can check just by going to task manager and clicking the performance tab. If you have a quad-core processor, you should see four threads under cpu usage history like this http://www.yafla.com/dforbes/images/call_of_duty4.png .
