Microwave was beeping a single beep once in awhile now nothing happens but the clock still works

A lot of the time when that happens the touch pad is bad and may have a colappsed air pocket on a pad. ( it makes the unit think you are pushing a pad ) The only way to fix it is to replace it (the touch panel) . Did you see any numbers coming up in the display. Like if the 3 pad was bad and making it beep it may have been showing a 3 in the display,. Always possible it could be a bad main board. But most commonly I have found it to be the touch panel. Try to unplug it and then plug it back in and try to set the clock. when you do, try each number pad and see if they all work. See if any feel different.

My computer has 3 beeps followed by 4 beeps and it is not displaying on the screen

Sounds like a bios error code. If you have a store brand PC like HP, Dell, Gateway there will be a section describing the beep codes, some manufacturers also have a series of 4 led lights on the back of the PC that correspond to different problems. Have you recently added RAM or other components to your PC?

Welcome to Fixya

Beeping sound is telling you there is something wrong with the hardware. Different beeps has different meaning. Please refer to this link for the standard beep codes of your computer.
