my laptop sometimes crashes suddenly and shows a blue screen for a second or less then reboots.
when it reboots it shows that there is no boot drive and tells to connect a drive and press any key .
then i force shutdown it and start it again and it boots normally.
can you guys tell me what the problem is.
it is an acer laptop
