It would be something really simple like the bobbin winder not completely in the right position. I hope the troubleshooting page will help.

try a new needle
make sure the bobbin is turned the right way in the bobbin case
rethread the machine top and bobbin
if these suggestions don't help, then the machine needs to be checked

Some sewing machines are extremely finicky about the direction the thread feeds from the bobbin. I had one machine that didn't care which way the bobbin fed and another that would stop after 2-3 stitches and protest. You could try flipping the bobbin and see if that helps.

do you have a manual?
try a new needle
adjust the top tension
try rethreading the machine top & bobbin

when you thread the machine make sure to use every thread guide
check to see if the bobbin is in correctly
try changing the needle--normally flat side goes to the back
the needle that your sewing with is it the right one for the thread & fabric
clean under the needle plate & bobbin area for lint or loose threads

Try this, totally rethread with the presser foot up, then pull the top thread, it should move smoothly, then lower the presser foot, now pull the thread, it should barely move. This seats the thread in the tension discs.

I be s 8763 was sewing beautifuly, took off pressure foot to make a buttonhole read the manual followed directions button holer kept gumming up with thread and the alarm kept going off, then got flustrated, put back on the sewing pressure foot now it is like the needle is out of line will not pick up bobbin, and is definately hitting something by the bobbin, will not sew

I think that your should try a new needle, it may be bent or have burr on it. It problem persists call Singer at 1-800-4singer, good luck
