If you’re Windows 7 system is acting unstable, and you’re not sure where to start, generate a System Health Report. This free feature is included in Windows 7 and Vista.
Click Start and type: perfmon /report in the search box then hit Enter.
Alternately you can hit the Windows key + R to bring up the Run dialog, type: perfmon /report and click OK.
This launches the Resource and Performance Monitor. It takes about a minute while it collects system data.
When it finishes, you’ll get a list of your system’s components. It gives you data on each component like the CPU, hard drive, memory and more. Just expand each column to check if there are any problems.
The report runs a full set of diagnostics on your systems hardware and software components. And provide you with errors and warnings so you can go in and fix them. Here’s an example of a driver for an external device that isn’t installed properly.
If you need more help from another colleague or tech expert, click File >> Save As to send them the report in HTML format. This works best if opened in Internet Explorer.
Generating a System Health Report is great place to start when troubleshooting your system. The report is detailed and lets you drill down problems that are component-specific.
If you’re looking for an additional troubleshooting utility, try Speccy. It will give you detailed information about your hardware and software components too.
Editor Update: It appears there’s a known bug with the reporting. If your System Health Report says you don’t have an antivirus installed, but you know you do, follow these steps.
