Internal drive cannot be found on my dell 560 desk top

I had a problem where something failed I installed new memory about a week prior 

went from 4 gig to 8 gig everything was working great.  A couple days ago i got a startup

failure I got back in.The following day I couldn't get in and haven't since. So, I gave up and 

reloaded windows 7 64 from my oem recovery disk.  I could not get in then because it couldn't find

my hard drive.  Digging around I found a driver for the hard here at dell support that has it is an urgent update. it is a zipped .exe app.

Since my windows install will not go any farther i tried opening the zipped folder in a rewrite disk,

flash drives, an external back up drive, my PC will not accept any as driver locations.  It is not in the old 

OEM drivers. This is what I need  R243144.exe.  The stuff i read says i have to unzip to a folder and run from my desk top or something similar because is is an HTTP file.  I can't do that cuz i cannot finish the install.

I also tried the diagnosis I got this message:

ERROR CODE 0151

Message ERROR Code 2000 - 0151

message hard drive 0 incorrect status

32 no additional sense information

So all this stuff you just read through above leads to my question:

Can I get a dvd with these updates ready to go? I know this is an old PC but it is plenty for the stuff I do

browsing, word processing and answering support tickets.

Is there a way I can get these drivers I need in a startup disk?

then I could load it perhaps.

Thanks in advance for any help
