System process

I need help with windoze. When I open task manager, the process "system" is constantly running at 99% and it won't go down. I don't know what wrong with it. It still runs at 99% when I start up in safe mode. This machine I'm working on is not mine, so a) I'm not going to install linux and b) no www.opera.com post. I would appreciate some help in fixing my "system" problem.

I'm the OP. I don't know what the PID is. Where can I find that? Also, I need to use Internet Explorer because firefox isn't working on the machine. I tried posting the Hijack this log, but the log was too big for the post. I ran adaware and I only found one bad tracking cookie. Any ideas?
