The 1st install of Win7 was an upgrade from XP
Some upgrade packs won't allow you to do a clean install, you have to have Vista or XP on the same drive before the activation is accepted. This can be averted with a registry key setting post install though.
Since your setup is not advancing past the post screen, I would suspect that either your DVD is bad or you have some sort of a hardware problem. If you have a configuration problem in your new hardware that may well cause the BSOD during the install.
As the first step of the troubleshooting remove everything from the computer except your OS harddrive, your CPU/cooler, ram and optical drive. Remove even the graphics card if you can use built in graphics for the setup. Then do a bios reset and CMOS reset and try installing again. If that fails you have to remove all but one ram stick, try again. If it still fails, remove the previous ram stick and try another. If even those fail, then you would have to suspect that either your DVD is bad or you have DOA hardware in your hands. It's common for self burned OS installation DVDs to be bad if they're burned with max speed, the installation disk is sensitive to burn errors.
I would just download the official ISO from digitalriver, burn it using 2x or 4x speed, do the setup and then contact Microsoft when the key is asked (and if you fail the automatic activation). The Microsoft people will tell you what to do from that point on. If you fail the automated phone activation also, you'll be directed to a support person (probably in India though). In the worst case you'll have to buy a new license but the company that 'sold' you the pirated license is going to get sued.
The series of letters RMCULXFER_EN per se has nothing to do with any sort of piracy. It's a part of the .iso filename.
