Diagnosing Windows 7 Performance Issues

Postby scruffy » Thu May 17, 2018 10:11 am

A broad question and a specific question.

I have a Windows 7 laptop with an i7-2860QM processor, 28Gb of RAM and two SSDs (one for the OS and one for data), and a workstation graphics card. Yet I frequently have issues with the computer running slow. I know there can be lots of different kinds of bottlenecks and many causes of lackluster performance. (For example, The W520 only supports my OS SSD at 3Gb/s.)

1) I know a lot has been written on optimizing Windows performance. I'm not asking anyone to re-invent the wheel. Can someone recommend a resource for methodically diagnosing, identifying, and solving Windows 7 performance issues? I'm familiar with the Performance Monitor, but don't know how to use it effectively to trace my issue(s).

2) Here's a sample issue I had. Today, I opened a large Excel spreadsheet (300MB), whichI eventually pared it down and then created a Pivot Table. Now that Excel window--and only that one window--will not completely appear/refresh when activated in any manner, despite appearing to run fine (per the Task Manager) and not taking up any CPU. I can open a separate Excel instance and that instance shows on screen fine. This is an example of the kind of performance issue I run into. Can anyone tell me what the underlying cause of this particular problem is? Is it just a Windows bug, or does it indicate some issue with my setup (e.g., video issue, swap file, RAM, etc.)?

Any recommendations (except "move to another operating system") are much appreciated.

7 year old CPU, 8 year old Operating system with a multitude of patches and bug fixes. New software optimized for new operating system i.e. Windows 10 (unfortunately). I updated to Windows 10 as soon as I could on all my systems running windows (unfortunately need windows for some things).
Unfortunately windows 7 is not great on SSD's either, should be, but isn't - make sure both SSD's are running in ACHI mode from the BIOS, make sure all drivers are up to date. Make sure TRIM for the SSD's is working - DO NOT run defrag on the SSD's.
For the age of the hardware it should still be pretty nippy, can you post the results of Performance Monitor?
I have been programming on computers since the ZX81.
I am an apprentice trained Electronics Engineer with qualifications to back it up.
I have been repairing computers since 1996.
Yet to some people I still know nothing...

Thanks for your response and willingness to help, Mr. T.

I'll be pre-occupied for a couple days, but I'll post something soon.
