PC HELP: Can't connect to Internet or shut down.

by JellehFish / January 31, 2017 2:49 PM PST

A couple of days ago my internet cut out unexpectedly (only on my wired PC) it took me a good hour of resetting various devices to get it going again. The following night, same thing happened, this time I had to uninstall my network adapter and reboot to fix it.
Today, nothing works. I've tried all the previous fixes and I get no connections available, limited connection, or connected to Internet, but anything that actually uses the internet just crashes.
It also is no longer shutting down properly, if I hit shut down it goes through the normal motions, the screens shut off, but the computer is still running for a few minutes before it boots back up to the log in screen. So far trying to shut it down at this stage has worked.

My PC:

i-7 3770k - 3.5GHz; Ivy; 1155
Sabertooth Z77 1155; DDR3; ATX; PCIE 3.0
Corsair Vengeance - 16gb; DDR3; 1600MHz
SSD - Samsung 250gb; 840 and 840 Pro
HDD - WD Blue - 1TB; SATA III
Corsair AX760 PSU
Zotac 1080 Amp Extreme.

Most recent hardware change was months ago, no recent changes in software.

Any help would be hugely appreciated.

Thanks Proffitt, you're quite right, there was a Windows update on the day everything borked.
I hadn't considered this as I had automatic updates turned off on W7, but W10 doesn't like that.

I couldn't really follow your instructions as there was no uninstall options for Windows updates (there was for all the other updates), I don't know why. I couldn't uninstall the driver via the device manager either, it just kept going through the motions but then almost immediately reappearing.

Trying to install new drivers failed on the basis that I had to uninstall the current one first..

In the end I managed to remove the update using the command prompt, and once again I have the Internet.

I'm not going to get my hopes up just yet though, this isn't the first time I've "fixed" this.

I'll report back in a few days, unless you have any advice in the meantime.

Thanks for your help!

Here I have been lucky on drivers.

But, some folk accepted drivers in XP to 8 and found out "don't do that."

For W10, we have to use the info at the link given to stop driver updates.

Fixed.

I've had no issues since rolling back that patch. Even if I do run into more, I think it would be safe to assume the updates/drivers are the problem.
I thought it might the lan adapter on the mobo, so thanks a ton for your help!

Good to read. My view on drivers is

In reply to: Fixed.

If a driver works, don't fix or replace it. Many folk learn to block, don't accept driver updates this way.

Aaaaaaaand it's back.

Title says it all.
None of the earlier fixes work, no new updates.

That's very bad news.

When all my fixes fail, it's almost always hardware.

BUT FIRST try this. Unplug ALL USB THINGS. EVERYTHING!!! and shutdown.

Remove the power cord then press and hold the power button for 60 seconds. Release and apply power.

Turn it on and wait for Windows to finish booting. Plug in your keyboard, mouse and try again.

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?
