My computer is very slow

[siwibu]

My computer used to never act up and actually ran so smoothly. I could play league of legends while streaming music, and video. And then all of a sudden a few months ago it just got very bad all of a sudden. It started by disconnecting my league game every so often and showing that I didn't have WI-Fi bars. So after weeks of contacting my ISP and yelling at them we came to the resolution that it was in fact my computer. I reset it to factory settings and reinstalled league. But now it has progressed to the point where my Wi-Fi will disconnect at the simplest things like while playing league, or even just browsing the web. I have anti-malware bytes installed and have ran scans frequently with no prevail. I also clean my disk weekly and still nothing. Please help.

I would run a program like HWINFO that can identify the make and model of your motherboard, and possibly the network card. Then I would go looking for updates. http://www.hwinfo.com/

You can also try a anti virus scan, you never know.

Does your internet act up on other devices? It might also be that your network adaptor is failing. See if manufacturer has a diagnostic tool.
