hi everyone , couple of days ago i got a disturbing error which prevent windows 7 64bit pro to start. After i startup pc i get this error : Error: Cannot open volume for direct access. Autochk cannot run due to an error caused by a recently installed software package. use the system restore feature from the control panel to restore the system to a point prior the recent software package installation. An unspecified error occurred__766f6c756d652e63 3f1 after that error windows is tring to start up but all i get is black screen wit the mouse pointer. Safe mode is working (only mouse - no Keyboard) but system restore isnt working. i also tried to run Installation CD but it fail to complete the installation. any thoughts ?
