Rather than playing 20 questions,
Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.
it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.
if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.
Use Etrecheck Pro for free:

The amount of data you get can be daunting. If you POST your report, some Readers here are willing to look over those reports, and can provide valuable insights.
Copy your report
In order to post your EtreCheck report, you must first copy it to the clipboard.
An easy wasy to copy your report is to use the "Share report" control in the toolbar. This text version of the report automatically removes any personal information. Never post personal information on the internet. Screenshots have been disabled for EtreCheck when running in trial mode. They are difficult to read and, unlike the text report, they can show personal information.
Then start a new reply on the forums, click the "Additional Text" icon, and PASTE
