Why / how did you decide to go with Fedora Linux?
It is a big/heavy weight Linux that tends to need more cpu, ram, newer h/w.
Did you look at other Linux distros which are targeted towards older, slower h/w?
Ones like Xubuntu, Lubuntu, AntiX, Bodhi, Puppy, etc, see http://distrowatch.com/
for other distros.
Also you might want to search what other users with your make/model h/w are using, it could make your Linux experience easier/better.
Search/browse LQ to see what is tripping up. other Linux users
As for installing Linux on a Windows PC, I would recommend making 3 partitions:
1)a partition for / (the o/s's root), minimum of 10 GB depending on distro;
2)a /home partition for user data, separate from root partition in case you reinstall Linux at a later date, make it as big as you can!
3)a swap space partition, minimum of 1x RAM (recommend 2x) useful for hibernate also if you are on a laptop.
