Ethernet Cable not Detected

by zippo364 / January 31, 2009 9:46 AM PST

Recently, I took my Dell Dimension 8250 Desktop to a friend's house, and accessed his internet through an ethernet cable, which required me to change the IP settings on my LAN connection.

When I returned home with my computer, my USB mouse, speakers, and internet were not working. I system restored, which fixed everything but the internet. Now, after trying several different cables, my ethernet cable is not registering in my PC at all: the light on the back of the machine doesn't turn on when it's plugged in, the "Cable Detected" box doesn't pop up, and under my Network Connections, there is no third section where my Local-Area Network used to appear.

Please let me know what the possible errors are, especially if it is something that can be fixed in the software, i.e. with drivers. I have already tried reinstalling my modem driver, and a couple of others, but nothing has worked up to this point.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
