XP does not recover from sleep anymore.Recovering starts in the normal way with "Windows resuming" and te iiii bar turning white, from left to right.When reaching the end, one of the three following things randomly happen:- bar stays white and freeze- a blue screen with white text flashes (can't read it, too fast) , followed by choice of 'try again' (which leads to a repeat of same story) , or 'complete reboot' - same as above, without the intermediate flashing of blue screen.Only way out is to select the complete reboot.I have tried all possible choices for sleep modes in power section of the BIOS, without result
