I'm afraid I don't know any of that stuff. I just know it's an old used Gateway with Windows XP.
Did you format the computer, or just reinstall XP?

Okay: Old Gateway and XP could be a problem. I don’t think MS has updated XP, for us average Joes in a while. And the Gateway is probably out of date and unable to keep up.
If your hardware is still doing okay, a fresh install of XP is probably in order. You’ll have to back up your data, but go with a fresh install and reload programs as needed. And only needs programs. You’ve probably accumulated a lot of stuff over the years, that out of date. also only go with what you need.
