black monitor after 3 beeps

[amiR9510]

I left my Dell Laptop Studio 1557 in sleep mode and when I turned it on, I heard 3 beeps( first one higher) then monitor stayed completely black while I could hear that CPU fan is working and after a while I heard the windows alert and other alerts which regularly I had when system came up. I changed the RAMs and I heard 4 beeps then kept same as before. Also pushed D button while restarting and saw different colours on Monitor. Could it be a VGA problem? I would appreciate if you could help me.

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

Thank you so much for your answer. I already moved to Canada and don't have extra accessories. Anyhow, I'll try your procedure and hope it works.
