I was having issues with errors that simply didn't want to be deleted so I simply reinstalled Windows which thankfully ment the errors weren't caused by my chipset/gfx card or anything like that. However, now that I've fully reinstalled Windows 7, my fps in games like LoL and Runescape is just horrible; Runescape is basically unplayable (inb4 "yes it is" joke) and my fps in LoL just drops all over the place constantly. I've run CCleaner and Norton scans/tune-ups and nothing has changed drastically. What could be the issue?
