MacBook Pro will not boot up nor enter safe mode/recovery mode

Hey guys, Im a college student. On moving out day I found that some one had thrown out a MacBook Pro. Took it home and realized why. It doesnt start up. It stays on a white screen for about 6 to 8 minutes and then goes to the apple logo and then shows a circle with a slash through it. I try to boot in safe mode and recovery mode but it wont go into those modes. It just repeats the same boot up. Im wondering if there is anything i can do to salvage this laptop or is it done for. Thanks in advance guys.

I have tried to use a completely formatted hard drive with no partitions on it. I took it from an older computer. When i booted mac while holding option, it would not show the hard drive. I guess it could not recognize it. When I did the same with the stock toshiba hard drive it would take a long long time but it would show the hard drive and recovery however when i clicked on any of the two it would show the apple logo then the prohibitory sign : the circle with a slash through it. So, i decided to purchase an OSX install disc. I dont know why it couldnt run using the C button. I had to again click option and then clicked on the disc. However, after this the screen just went white for a while then showed the apple logo then the prohibitory sign again. So i replaced the hard drive with the formatted clean hard drive and did the same and it would just show a white screen then after about 8 to 10 minutes, it shuts off. So i then tried to format the stock hard drive to make it clean and now it wont show the hard drive when i hold option on boot up. Im lost. It looks to be the 13 inch mid 2010 macbook pro model. I can not enter recovery mode for some reason or anything really other than when i hold option. PLEASE HELP ME.
