Sounds like you need to replace your CMOS battery.

      Hello guys,
      I've a really weird problem. My laptop has started beeping when use nvidia gpu yesterday. I dissambled my laptop and tried to plug out every single hardware and test them one by one. There's 22 beeps and equal interval beetween them.  It goes shutdown after that 22 beeps.
       
      My laptop is Clevo W650SJ and it uses Nvidia 840M gpu. That problem isn't causing because of windows or installed driver cos i tried to reinstall windows but it started to beeping when w10 installer check devices. Also I've bios password on startup , if i don't type password and hit the enter , it starts beeping after 10-15 sec. Also fan speed goes up to maximum and it doesn't slow down untill i shut it down or shutdown itself.
       
      If i use any program or run a game which uses nvidia gpu , it starts beeping but if i close the game on first beeps , beeping is stops. But fan speed still maxiumum until i shutdown to pc.
       
      I am looking a way to fix it. I didn't make any changes on my pc before than this problem.

      I’m running an Alienware M17xr4. Problem is when I change my A11 bios configuration to PEG and disable my igpu, my screen reboots to a blank screen followed by 1 beep. Then the screen lights up but is all black and seems to remain that way until I run out of patience. Does anyone know what  is happening?
