Highly disappointed!!!!

Hello everyone, I have quite the little story that is very frustrating and still unresolved. A couple years ago (2010), i bought a "brand new" dell Inspiron 15R for college, thinking that this computer would be a great starting place for my academic career. Boy was I wrong. Within the first YEAR, I had to contact tech support 3 or 4 times to solve issues this computer was having. And just when I thought everything was finally working well, the hard drive failed, causing the computer to not even make it to the first windows screen upon start-up. To make matters worse, this happened the day before finals week! This was beyond frustrating, but to make matter even worse, my warranty was now expired and i could not get it fixed from dell, awesome. I called their support, only to get some foreign guy named "greg". Greg told me there was nothing he could do, again, awesome. So being the computer girl that i am, a disassembled the laptop, removed the hard drive and started to do some research.  My SAMSUNG model: HM321HI 320 gb hard drive, was apparently recalled 2 years before i purchased this computer. 2 YEARS! Needless to say, i was, and still am pretty upset Dell would use this hunk of  in a computer that they then in turn sold to me. The hard drive is finished, and i knew it so i went ahead and ordered a new drive and installed it perfectly with no complications.  This is when i realized that dell had not sent a cd with the drivers, OS, or anything for this exact situation. I bought and installed Windows 7 back onto the computer and tried my best to install the drivers, and in the right order. However i was largely unsuccessful, and my computer is now collecting dust.  Which brings me to my main point and question, is there any way i can possibly obtain this cd or can someone out there in the world help me install the drivers so i can use this thing? I return to school in a week and would really really like a computer to do my work on. Thank you in advance.
