<human>:  How do I fix my computer that's been running slow?
<bot>: Start by checking the general health of your computer. Make sure it has the latest updates to its operating system installed, run an antivirus and anti-malware scan, disable any background processes and applications that you don't need running, and check the amount of free space on your hard drive. You can also try running a disk defragmenter to help optimize your computer's performance. If none of these solutions help, you may need to contact a professional technician for further help.
