Windows XP: setupdd.sys "Error code 7"

Solved
Rex2481 -  
Hello,
I have a problem with my PC. I moved it and took the opportunity to give it a gentle cleaning, and I reconnected everything perfectly like before.
However, it wouldn't restart. It starts up, I see the motherboard BIOS as usual, then it launches the boot program but the screen is black and it displays nothing.
After about 5 or 6 reboots, it shows me a message saying that the boot could not be completed because certain Windows files are missing.
Since I have a laptop, I put my hard drive in an external hard drive case and it starts up perfectly; I can see all my files, so I transferred all my important files to another external hard drive and formatted it using the computer manager.
Then I reconnected my formatted hard drive to my PC and inserted my Windows CD. The installation program started, but after a few moments, it stopped and told me that it was impossible to load setupdd.sys because the error code was 7. However, I read that the Windows 7 error code indicates that memory control blocks have been destroyed. I don't quite understand why and what I should do.
Thank you all for your responses. 
Configuration: Windows XP Internet Explorer 7.0

    Well, I’m answering myself to help those who might have the same problem...
    It's the RAM sticks that were poorly installed... due to a slight displacement... fragile... ^^

      Thank you rex2481 that one day you alone answered your question. I had the same problem and yes, you just need to remove the memory sticks and put them back in place or remove the last RAM installed, which I did and it worked. I didn't need to format what I was about to do, so follow all this advice if it happens to you, it can save your computer; bye.

      Thank you, Rex, a few little phrases that will make a lot of people happy, I'm sure, including me :)

      And to think I thought it was a bug in the CD...or in the "systemDD" Hard Drive...I broke a CD just for this nonsense :s

      Thanks again!

    My dear Rex2481, allow me to call you "my dear" because you saved my life. Tonight, you will fall asleep with this idea of a renewed chivalrous spirit:
    it was indeed because of the memory sticks that I had this message on setupdd.sys and error code 7.
    I removed them and then put them back, and it works: well done (I would have never thought of that)
    Long live to you.

      For me too, it's the RAM sticks.
      Thanks to you Rex2481, I didn’t struggle (too much), although I had already reformatted. In the end, I was expecting worse.
      May all the gods (including the one of computing) bless you for life.

        Good evening, by the way, I am experiencing the same problem as yours, only my RAM is integrated or soldered to the motherboard. I am using a Toshiba A60, so how should I go about desoldering this memory since the BIOS does not provide any option to disable it? Thank you all because I believe you can help me.

        Thank you my friends, in the end it was the RAM that caused this conflict.

        Indeed, it was the RAM full of dust, just clean them and put them back, it will start.
