QuestionMy computer is slow, especially when using Chrome. It also takes loooong time to switch off completely after I command. I have tried to stop the start up apps but no change.

She has more than 20 years of experience creating technical documentation and leading support teams at major web hosting and software companies. Nicole also holds an MFA in Creative Writing from Portland State University and teaches composition, fiction-writing, and zine-making at various institutions.Chrome uses a lot of RAM. If you have a lot of tabs open at once and don't have enough RAM to support all of the open tabs, Chrome will often hang or crash. You can see how much RAM Chrome is using by pressing Ctrl + Alt + Del and clicking Task Manager. If you have any extensions installed in Chrome, try uninstalling the ones you don't use (or disabling them) to see if that helps. If not, you may just need to have fewer tabs open at a time or increase the amount of RAM in your PC. You might also consider closing other programs while you're using Chrome, or see if you have better results with a different browser like Edge or Firefox.
