Okay, let's start at the top.
1) Uninstalling programs does not speed up the system. It simply frees up disc space, which has no impact on performance (unless the disc was literally full).
2) Using system restore does not uninstall programs. It replaces the registry and system files with versions from the date selected, nothing else.
3) If your system was running slow it was NOT because of how many programs or games were installed, something else was at work.
4) You said other browsers won't open. I have a hard time believing that if there is nothing else wrong with your system other than IE not opening that Firefox or Opera or Safari would not open. There is no connection among IE and any of the other browsers. IE is part of Windows, the others are not.
Do you have an anti virus app installed? If so, run a full scan of the system with it. ALSO run a full scan with MalwareBytes. Let's see where we are then.
Also, do you have an original XP cd? We may need that later.
