A week or so ago, my computer with Windows 8.1 installed slowed down significantly. It wasn't a gradual slow down, but I do not recall any events (new installations or similar) that accompanied it. How can I approach debugging it in a structured way?
I will provide information upon request.
The computer is HP Probook 4530s with an SSD installed at a later point (but added much prior to this). The computer is slower overall. It's most noticable when browsing using Firefox and viewing flash videos, but it's also noticable when opening and using other programs, windows explorer etc.

At first glance, we will need more information. Make and model of computer to start with. Whether you have an HDD or an SSD could matter. Also, what is your concrete definition of "slow": is everything taking longer, is a specific program not responding as quickly, etcetera. – Doktoro Reichard – 2014-05-14T03:20:19.073
Check the event log to see if there is anything of note coinciding with when the computer slowed down. Also, it's likely that there is data in the performance monitor that can provide hints as to what is actually taking up the computer's time. For example, it's a big difference between a CPU-bound system and an I/O-bound system (even though I/O-bound sounds unlikely given the use of a SSD). I'd look at wait times, RAM and swap usage and context switches for a start, but go through those lists as there are plenty of other useful metrics available. – a CVn – 2014-05-14T09:54:29.597
