Make sure that the program controller is receiving power - step down supply. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html
Since the clock is resetting it is a fault on the main board and the processor as it is tripping. So check power, check for faults mentioned above on the board. Also if there is fault of the magnettron leak or a waveguide leak then clean and check insulation.Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had depositedthen it must be checked or replaced.

Now keeping clear of the microwave, switch on, use a cup of water inside to test. If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.If there is heating without any issues, you can use the microwave safely
