Gateway FX - P-7805u

Hi. I have a Gateway p-7805u with Vista os. I recently purchased a new set of recovery disks from gateway because I thought the previous discs I had were defective. Anyway, after going through all three recovery disks, and restarting the computer, I noticed that there is a flashing cursor in the upper left hand corner of the screen which is only black. When I connect the hard drive that has the supposed recovered o.s. on it to another computer via a USB connection, I discover that there are files there--the recovery disks did transfer files to the hard drive. However, it is not booting to vista. Has anybody experienced a similar problem? I notice that there is a class action lawsuit that has been initiated against Gateway for this model computer along with several similar models. I think there is a video card issue. I have personally noticed that the screen would freeze up on the laptop before when it used to work. I have a feeling that there is a problem with the master boot record. Any comments/suggestions would be greatly appreciated. This problem has me really frustrated considering the fact that I paid so much money for this laptop years ago. Thanks again.
