Here I go again. My son has a Toshiba Tecra T9100 and when you switch it on it has the following on screen:
we apologize for the inconvenience, but windows did not start successfully. A recent hardware or software change might have caused this.
If your computer stopped responding, restarted unexpectedly, or was automatically shut down to protect your files and foleders, choode last known good configuration to revert to the most reent settings that worked.
If a previous startup was interrupted due to a power failure or becuase the power or rest button was pressed or you aren't sure what caused the problem, choose start windows normally.
(then there are the following options)
Safe mode
Safe mode with networking
safe mode with command prompt
last known good configuration(your most recent settings that worked)
start windows normally
Have tried them all but about 5 seconds into loading it flashes to a blue screen with writing on (but not enough time to read what it says) then switches off and then it starts all over again...
any ideas anyone??? (crikey got writers cramp now

)
