i have canon 1100d camera from a week or so i m having a problem in manual mode?

Keep adjusting the exposure until the -3 stops flashing then adjust it some more until the indicator is in the middle of the scale at zero.

To get a start point set the camera to P mode, frame the shot and half press the shutter and note the aperture and the shutter speed the camera intends to use.

Go back to M mode and dial in those values. Now make your adjustments as necessary for the photo.

With experience you will learn to judge by eye roughly where to start so you can home in on the ideal exposure more quickly when using manual.

Start with "sunny 16". f/16, ISO 100, shutter speed 1/125. Take a pic outside in the sunshine. It should be properly exposed. Now you have a baseline that you can change according to conditions. Also read page 101 of your manual to deal with Exposure Compensation.

1) and 2) semm to indicate that you've set a too short exposure time together with a too small aperture. Upping the ISO can only help yopu in a very limited way.

For any further comments, I'd need to know where and when and under which kind of light you were trying to take these pictures.

Read your manual.

Manual exposure isn't hard, but you change shutter speed and aperture (leave ISO alone) to get a correct reading. While knowing your shutter speed and aperture are useful, as long as you keep your shutter speed up (the first rule, there are others) what's important is the correct exposure.

Time to learn about the Exposure Triangle - Aperture/Shutter Speed?ISO.
