Is there any way to investigate what is causing slow loading times on my PC?

Yes. One way to investigate slow loading times on your PC is to check your system for malware, run performance tests and scans, and review your programs and services to see if any are taking up a large amount of memory or CPU resources. You can also use tools such as Task Manager and Resource Monitor to track and monitor resource usage. If your issue appears to be related to the hard drive, you can also check Hard Drive health using chkdsk or Windows diagnostic tools.
