I purchased a set of external speakers for my computer. I had been using the speakers in the monitor. I unplugged the speakers and plugged them into my laptop for a day. When I plugged them back into the desktop I had no audio. So I tried the monitor speakers, nothing. I decided to go to the device manager and investigate. I got an error message, "an administrator has blocked you from running this app. So I went on line and tried finding a solution. Of course when you say "no audio" the first thing they recommend is going to the device manager. I tried finding a fix for the Admin problem but nothing worked. Also, the computer no longer recognized the DVD player. It just says "no dvd player found". And I cannot go to the device manager to look for it.
Do you have any solutions?
