Hello, I need a little help, I have an acer aspire 4551 running windows 7. I am trying to reload back to factory. I have 2 sets of the recovery disks. the first set will load the first & second disk but not the third. it kicks it back out and says insert recovery disk 3.. the other set does the same thing. but will not take disk 2. I installed a different DVD drive and also a different Hdd and still no luck. Thanks
