Alright i have taken a look at your dump files. You have a major issue. Sorry to inform you. There is a file that got corrupted entitled PSHED.dll. Now this file is for Platform Specific Hardware Error Driver. Sadly it cant be replaced or just copied from another install. Hence the title Platform Specific. Included in your files is a corrupted hal.dll error as well.
The only way your going to stop this behavior is to reinstall.
