I have a Gateway Notebook that I baught in 2010. it has a first gen I3 processor with 4 gigabytes of shared memory for a video processor. My 500 gig hdd stopped running properly and it was failing every diagnostic test so I bought a new one. The first one that I bought was a 7200 rpm drive, then I tried a 5400 rpm SATA drive with a 8 mb buffer. I inserted my first factory recovery disk that I made when I first bought the computer and everything worked right, it installed both disks and was installing windows. After the disks finished installing and the computer went through 2 more screens with progress bars for installing the computer would reset and try to start windows to finish the set up, when windows was starting it would say windows is installing files, once that was done and ERROR screen would pop up with no ERROR code but it would say that the setup process can not continue because windows can not load on this computer hardware. when I reset the computer the ERROR message pups up again but now will say Windows can not complete the installation process, please restart the installation. I re tried this 4 times now with 2 different HDD. If any one has any suggestions on what to do, I feel lost now, HELP!
