My Toshiba Satellite M50 wouldn't startup. It gives the blue screen everytime,its like an endless loop. I recently used the recovery diskto reinstall windows even then this problem persists. The error message says the system has recovered from a serious error.. "Error code 1000007f, parameter1 00000008, parameter2 80042000, parameter3 00000000, parameter4 00000000". The dump files are attached. I really do need this system to work specially for my upcoming presentation. What to do? Please suggest a solution.
