I have a compaq presario v6000 laptop with vista that will startup windows for about 2 seconds and then apparently goes to sleep mode.(blank screen lights all on no noise from drives) When I shut it down using the power button and restart, it goes to the screen where you can choose safe mode etc. When it is run in safe mode it works fine.I dont have any discs for it and this machine was never backed up internally. Im not sure what direction to go with this any help would be appreciated.
