My computer has been taking a long time to boot to the login screen, and it can take several minutes to become usable after I enter my password. Windows sometimes feels like it is stuttering or taking ages to respond, although mouse movement and audio from videos remain smooth. Games also take a long time to load, but they generally run normally once they start. This has been happening for around six months, with only one game having noticeable problems during play.
The computer is about five years old. I recently tried upgrading to Windows 11, but the upgrade did not resolve the issue, and the system was not officially compatible. I have replaced the original drive with a larger SSD and added more RAM. Both drives report good health, and neither is close to being full. The PC may be somewhat dusty, but I am not sure whether that would explain the slow startup and login process. What should I check to determine whether this is a Windows, startup-program, drive, or hardware issue?

It sounds like the main problem is Windows startup and the period immediately after logging in, rather than gaming performance. Check Task Manager's Startup apps tab and temporarily disable nonessential programs, especially launchers, update utilities, and hardware-monitoring tools. Also look at the Processes and Performance tabs while the computer is slow to see whether disk usage, memory, CPU, or a particular program is maxing out. Running a malware scan and checking Windows Event Viewer for disk or service errors would also be worthwhile.
A drive-health report is useful, but it cannot rule out every storage or controller problem. Back up important files before changing disk or BIOS settings, then check the SSD manufacturer's diagnostic tool and review Windows system logs for storage warnings. Avoid compressing the entire system drive as a first fix; it can add overhead and will not address a failing service, driver, or startup application. Cleaning dust and checking temperatures is sensible, but overheating usually causes broader slowdowns rather than only long boot and login times.
