Windows 10: PC won’t display anything despite lights and everything else seeming to work, how do I fix...

I’m not really sure how it started or what went wrong since it was working fine and well the morning I had left, but when I had gotten back the PC was stuck on the boot up screen, and at this time I could still see it on the monitor. I googled a solution to this and I found a suggestion saying unplugging everything should fix it, so I removed the HDMI cord connecting the computer to the Monitor along with everything else and when I put it back, it wouldn’t even come back on. It won’t display on anything, not on other monitors or even TVs, but the lights from the fans turn on and they even sp

Volume Mute Light won´t change color

Before I follow your suggestions, a quick update: as the updating didn´t seem to work I stopped trying and just left it alone for awhile. About a half hour later I looked over and saw that the mute light was now blue. I tried the button but it and the volume buttons did not work at all. On the screen I was told that I needed to reboot, which I did and now the system has returned back to the way it was before: everything works except that the mute light does not change to blue as it should when the speakers are not muted. WTF?

 

Volume Mute Light won´t change color

I have an HP ProBook 6440b with a Win 10 Pro os. My problem is the volume mute light (#5 in the service manual, page 2-6). The switch works o.k. and shows when the mute function is on or off on the desktop but the light stays orange (muted position) regardless of the function being on or off. I know that the blue color is there as I see it flicker so slightly during upbooting but I can´t find out how to have the blue color show when the speakers are not muted. The wireless button (#4; page 2-6) changes color and the function works properly when pushed (tried it as a function comparison test) so I think this may be a slight software glitch in the sound system code but how to find and fix is way beyond my knowledge and skills. If anyone knows how to fix this problem, please do tell but baby steps please as my computer skills are truly limited (old dog, new trick syndrome rules here).
