I have a
Sony Vaio VGN-SZ61MN laptop which is running windows 7. One of its memory cards is not working and has been removed from the slot.
At startup I can hear
1-long beep and 2-short beeps.
Computer starts normally but the screen is totally black. I mean nothing at all even at the startup. I can login by typing the password and hear loging in sound as well.
I can also connect to this machine from my other laptop using Remote Desktop Connection. I checked the Device Manager and also Dxdiag command they all okay.
What could be the reason for display problem? Graphic card or monitor or anything else?
Your expertise would be much appreciated !
