Get a history of CPU/memory usage
Solution 1:
Windows Performance Monitor (perfmon) should do the job for you; you can configure it to log to a file, so just enable the counters you need and it'll log as much as you want.
Solution 2:
- Start > Run > perfmon
- Hit the plus sign next to Performance Logs and Alerts
- Right click System Log and select properties.
- Adjust the sampling times to whatever you like
- When you are done, hit OK then the plus sign at the top of the window.
This page gives a pretty good step-by-step with screenshots
Solution 3:
I use PolyMon to monitor these kinds of things. You can define various "alert" conditions about which you'd like to receive notification, so I get notified if one of my servers is having a problem.
But it also stores all these results in a long term database, so I can look back at the memory usage of server "X" and see it's memory usage trends over the last N days/weeks/months/years.

Solution 4:
You may consider using a monitoring solution like zabbix, zenoss to collect and analyse your perf counters.
Solution 5:
Cacti is a great webv based graphing programme. It can graph CPU, memory, disk space, etc, etc. It can also be extended with your own plugins.
