Ok I have Lenovo h320 pc which I recently upgraded the graphic card and RAM . It has been around 1 month since the upgrade and it was all working fine. But today when I started the pc first it started to beep continuously and fan was ok. I restarted many times. And then the fan was exceptionally fast and loud and there was a very short beep which stopped but the fan didn't and then my pc started but I shut it down to prevent damage . Please help and tell me what should I do
