CentOS 5 64Bit WONT BOOT FROM CD HELP!!!!

Let me get this straight. You're trying to boot from the CD for CentOS, and if you can't get it to work, you're going to scrap Linux altogether? That doesn't make a lick of sense. I have tried CentOS, and wasn't too impressed with it (being new to Linux for just over 2 months now). I have downloaded and tried 20 of the top Linux operating systems. So far, I find Kubuntu to be my favourite. I would readily recommend Ubuntu/Kubuntu, OpenSuSE, Fedora, Mandriva, Linspire/Freespire (in that order). I won't recommend Debian because their supposed "LiveCD" wants to partition and install rather than boot from the CD. I won't recommend SimplyMEPIS as it loaded with what I can only term as a "drunk screen." The entire screen was blurry (to the point you could barely make anything out) and it appeared twice, overlapping (like a drunk's vision). I won't recommend Gentoo because it simply will not load whatsoever for me. There's another distro I won't recommend but the name escapes me right now. I'll have to go back through all my LiveCDs to find out which one it was, but it wouldn't load properly either. Anything that gives me a bad experience I toss in the toilet (so to say). Sabayon looked pretty decent. gNewSense (or as I call it, gNuisance [probably a better name for it]), if you're up for nothing but free software, isn't too bad.
Just because one version isn't working for you, don't give up on the system altogether. Try a different version. If my experience were limited to Gentoo and SimplyMEPIS only, and then remained with Windows, I never would have discovered other beautiful systems such as the ones I would recommend. Some of the systems I have downloaded I haven't tried yet because they are only available in an InstallCD, and I like to test them first. If you will take a recommendation, wait until the 18 of this month and download a copy of Kubuntu 7.10 and give it a shot. Or you can get a copy of 7.04 now and try it. Whatever you can get to work, test it out and get a feel for it. If you don't like it, put it aside. Those you do like, decide which you like better and make use of it. I wasn't sure whether I would like Linux at all, so I installed it to a secondary harddrive while keeping Windows on the primary. In the last almost three months, I have maybe used Windows twice. Other than that, I have not touched it.
I have never liked the idea of pirating software, but unfortunately I don't have thousands of dollars to buy all the programs I would use on a regular basis. I have always bought my music, videos, and games, but never my programs because they are ridiculously priced. Linux has enabled me to get away from using programs illegally, which I am grateful for. Linux distros come jam-packed with programs readily available for your immediate use, unlike Windows. And so I have been leaning further and further toward eliminating Windows from my primary drive and installing Kubuntu permanently.
