My Acer ( Windows Vista Home Basic)laptop has suddenly started to have a closedown problem.
Close downs seem normal then... Every third or fourth closedown a blue screen appears with Message and
STOP 0X0000007E (0XC0000005,0X81C969BA,0XAE083C30,0XAE08392C).
I then have to do a forced closedown and on the next startup the computer boots normally.
Last Known Good Config and also System Restore failed.
