Windows 7 freezes after new install

OK so my pc was working fine i was using DEV-C++ for my c programing class and everybody was happy  . Then a friend recommended to instal Eclipse and i did but i was messing with the path in Environment Variables and mess them up so i decided to do a reinstall on the comp. Now i started the installation deleted all the old partitions created 2 new, system created one system partition and started the install all went well. First time running the new install i installed the chip-set drivers from the cd that came with my mother board,installed the network adapter and restarted the PC. After the Pc boots and my desktop appears everything works fine, as soon as i click on something then everything freezes and i cant do anything and commands don't respond at all, restart again but Pc goes to repair mode and give me some diagnosis and says that i might have HD malfunction. I tried to reinstall at least 5 times same thing every time. I know its not the windows 7 copy since i used the same copy on the lap top i am using right now. I am thinking its my HD but why it was ok just before i reinstalled the PC literally 20 min before new install ,and 20 min after the new instal HD is broken does not make sense to me. HD is only 3 mounts old with most of the other components.Am i missing something any help is appreciated. Thanks!!!
