Ram issues?

Did you have a button down the bottom which says "Show processes from all users"??. Mind you, the only thing that says 99% is more likely to be the CPU usage (system idle process most likely), not the Memory (Private Working Set). None of the memory counters report in percentage in Task Manager (oh, except for the status line, but that includes cache, which is also "available").

You can always run Perfmon to look at the per process report. Task Manager is great for the basics, but Perfmon is much better if you are troubleshooting.
