Hello everyone, I have a problem with my dell 1501 laptop with windows vista. The laptop was in sleep mode when i opened it up it was frozen, ctl alt del did nothing so i just powered it down. Now when i try to start it up it powers on, the fan runs, and i hear the hard drive spin but the screen stays black. Also the indicator lights for the num, caps, and scroll lock flash once and then the scroll and caps lock lights stay lit. I have replaced the cmos battery and removed and reinstalled the memory boards. But still nothing, I have read in some other posts to listen for a beep at start up but i do not hear one. I have read so many blogs and forums that info is very scattered and if anyone can help please i need it.
