My DVD drive doesn't read, so a USB flash drive is my most viable option here.

I hope it's not a hardware issue, so I'm at a point where I'm ready to format my C: drive (with the OS on it) and reinstall Windows 7. In short, I can't get my PC to boot up, even in Safe Mode (hangs indefinitely at CLASSPNP.SYS), and none of the System Recovery Tools can help me at this point. I appreciate all the links and help you guys have offered. I did manage to get my PC booted up (maybe only once, but I'll take it) using the boot USB and then running System Recovery tools (Memory Diagnostic.no errors, but upon restart Windows started up). EDIT: Thank you so much, you guys are awesome.
