My roughly five-year-old PC has been taking a very long time to boot to the login screen, and logging in can take just as long. Once Windows is running, opening things and performing basic tasks often feels delayed or stuttery, although mouse movement and audio usually remain smooth. Games may take a while to start but generally run normally afterward, with only one game having occasional problems. This has been happening for around six months. I upgraded to Windows 11 even though the computer was not officially compatible, but that did not help. The system has a larger SSD and additional RAM, and both drives report good health with plenty of free space. The PC may be dusty, but I am not sure whether that would explain the symptoms. What should I check to find the cause?

A drive-health reading being good does not completely rule out storage or file-system problems, and available capacity alone does not prove everything is fine. Run the manufacturer's diagnostic tool, check the Windows system files and file system, and look for errors in Event Viewer. I would not compress and uncompress the entire system drive as a first fix—it adds unnecessary writes and may shorten the drive's life without addressing the real cause.
This sounds more like a Windows startup or background-process issue than a gaming-performance problem. Check Task Manager for programs with high disk, CPU, or memory usage, especially immediately after signing in, and review which programs launch at startup. Event Viewer can also show disk, driver, or service errors during boot. Make sure important files are backed up before changing BIOS, partitions, or anything involving the drives.
