Here are my problems that I have with my computer. Everytime I try to play a video, I get the video but there's no sound. Its like watching tv with the mute button on. It says that there is no device installed and I have a red x where the volume is. I have tried everything and at my wit's end!!!

Also, It wouldnt turn on and I wouldnt be able to get onto the INTERNET. Sometimes it would eventually turn after about 10 MINS. or 15 mins. or 30 mins. Then yesterday MORNING I tried to turn on my computer, it wouldn't turn on. I tried everything.

I unplugged the modem, unplugged the ethernet, the cable that was on the back of the modem, unplugged my monitor, unplugged my keyboard etc., etc. I must have called Comcast about 6 or 7 times in the past day and a half. Finally, at about 5 pm today, my computer finally turned on and was able to access the internet. Don't ask me how my computer finally turned on because I don't know.

I'll give you some information about my computer.

One more thing, my computer doesn't look right. The font and the colors of my computer are not what they were before and it seems like there windows basic or windows standard which is what I dont want.


Can someone assist me with all or any of these problems? I would really appreciate it. Thank you.
What operating system and is it a newly installed? Try installing the Audio driver and most likely the chipset and video.Its not newly installed. I've had the computer for 5 YRS. I've tried installing the audio driver but it didnt work. You may have gotten a new driver installed from Windows Updates. Go into your Hardware/Devices/Sound and Video and Game Controllers. Right click your audio device and choose Properties. On the next box click the tab "Driver". Choose to Roll Back that driver.

Also, before doing all this just make sure your speakers are plugged in and powered on. Sometimes it's the simplest things that slip past you. Thank you for your help. I would've responded sooner but my computer froze on Wednesday night and couldn't get on yesterday and most of today.

Windows update doesn't work for me for some reason. I don't know what else to do?

I already looked at the audio devices and drivers and stuff and it doesn't seem like I installed right. Because when I try to install it and restart my computer it says that the driver isn't installed. Bottom line, is that I still have no sound. I've had this problem before, and when I did, another thing that I had a problem with was the network. The Network Location Awareness service wouldn't start due to some internal error or another. I read online to try to use the command Code: [Select]sfc /scannow in an elevated command line. This is what fixed it, and I realized that it had to be due to shutting the PC off without shutting down the computer. I'd give this a try if you haven't already.
Another thing to try is uninstalling all the audio and graphics drivers and then manually installing them.
