If you are using a 64 bit PC i suggest you look at Fatdog: http://distro.ibiblio.org/fatdog/web/
which is a fancy version of Puppy Linux, but optimized for 64bit.
FatDog64 runs like fired from a rocket launcher, even on the mentioned hardware. Some of the Core 2 Quads are great, and 4GB DDR2 is plenty for a Linux install, as well as the graphics card.
pcpunk provided my favorite app to use to create a bootable Linux Mint installer, if no USB stick is available, a 2GiB or larger SDHC card on a USB card reader does the same. Much faster than using DVD's, and in the long run, a lot of saved cash. That single 2GiB SDHC card, or 4GiB USB stick or larger, will outlast 10 or more of the 100 count sleeves, longer if these are gone through fast.
OptimusSemi-Prime, to our Linux Community of Bleeping Computer Forums!
We're happy to have you here & hopefully can answer most any question you have. Speaking of which, there's no such thing as a 'dumb' question here, we all began where you are at this very moment & had many of the same questions ourselves. So please don't pull your hair out over something that may can be dealt with in minutes.
Nick also provided a easy way to burn ISO's from within Windows 7 or higher, the cool thing being, no extra software needed, it's included with the OS. While I place a check in the 'Verify disc after burning', this is optional & not a requirement.
Good Luck with Linux Mint Cinnamon, if that doesn't work, I suggest the MATE edition instead.
Have Fun with Linux !
