HP pavilion a1310n wont load windows?

My hp pavilion wont run windows at all. I turn it on it shows the blue hp screen then it goes to a black screen giving me the option to run windows in Safe Mode, Safe Mode with Networking, Safe mode with Command Prompt, Last Known Configuration, or to start windows normally. But i clicked on all of them and none of them load. When i click Safe mode, sfafe mode with networking, and safemode with command prompt it loads and says multi(0)disk(0)partition(2)\WINDOWS\Syst… 32\Drivers\ and then after drivers\ the names are different but they all stop at Drivers\Mup.sys . When i try to load windows normally or with last known configuration, it just restarts the computer and it does the same thing all over again. I cant do anything... does anyone know how to fix this?
