Why is my computer running so slow

Most likely you just need to run and Anti-virus software or optimization program. I’d recommend you’d run a Malwarebytes scan on your computer. If your computer doesn’t have any viruses, you can try and run CCleaner to get rid of all the junk files in your PC. If you are good on both parts, then you should try and clean your PC. Accumulated dust may decrease performance of your hardware causing it to throttle. If all else fails, its most likely that your hard drive on your computer is slow and is showing age. You might want to upgrade to an SSD for better results.
