PC continuosly beeps on startup

so i moved my pc like 5cms from its original place (i know it sounds dumb) to grab a cable that fell behind it ..and after i moved it back everything froze , then i restarted to fix it and it started to contiuosly beep and there was also the black screen ..and there were like 10-15 beeps ..a pause then the same amount of beeps and then it would turn off ...and then turn it back by itself and the beeping would start again .
