I have my friend's laptop(Samsung np-rv508). When i turn on after the 'Windows start up' i get a black screen with mouse cursor. 'Windows key + U' is not working neither press shift several times until the sticky keys window appears(it shows only yes/no options) and sometimes i get the message error "The instruction at 0x71B7.... referenced memory at 0x719E... The required data was not placed into memory because an I/O error status of 0xc000...".
I have installed kbuntu and it's working without error. When i installed win7 i get the same black screen with mouse cursor.
What i can try?i need install win7.
