for past 3 or 4 days i have been observing that during booting after the Windows 7 logo appears my screen is going black & it remains as it is(nothing is happening any more).... until i get annoyed & restart it again... then it boots properly & finally the desktop is coming....
this is happening everytime whenever i'm booting..... because of this everytime whenever i boot my pc i have to boot it twice.....
please give me some solution.....
thanks in advance
