Our internet won't connect on our PC, even when manually connected with the ethernet cable, but all our wireless devices such as iPhones and laptops connect just fine. We troubleshooted and were shown a message saying 'The Diagnostics Policy Service is not running, click to run as an administrator.' After clicking we are shown that the error is that the Diagnostics Policy Service is not running (basically going in a circle), Error 5. Everything else on the computer runs just fine, as far as we know.
The night before this happened we found the PC tower a bit lopsided and we think our cat got on the computer table because papers were scattered. Is it a possibility that the tower being knocked made something become loose which is stopping the DPS from running?
Windows 7 Ultimate.
Lenovo computer.
We have tried multiple system recoveries which have all failed.

Open services and make sure the service is started.
Hi,
The tower may or may not be an issue but that can be determined after we perform some troubleshooting steps.
Follow these methods mentioned below and check,
Method 1: I would suggest you to follow these steps.
a. Click on Start button.
b, Enter services.msc in Start search option.
c. Right click the Diagnostics Policy Services and start the services.
Method 2: This issue may occur when the account Trusted installer is missing the permissions for the key below:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DPS\Parameters
Permission needed: Full Control, Read
Note: Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the
registry, click the following article number to view the article in the Microsoft Knowledge Base:
(http://windows.microsoft.com/en-US/windows7/Back-up-the-registry )
a. In Registry Editor(click start, type “regedit” and hit enter), browse to the above mentioned key for which you need to add permission.
b. Right click the key, and click Permissions. (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DPS\Parameters)
c. Click “Add” Button under usernames. Make sure Locations is selected to be the local computer.
d. In the "Enter the object names to select field, type "NT SERVICE\mpssvc". Then click “Check name.”
e. Click OK.
f. Then select the account which appears in the list, and add the appropriate permission (Full Control, Read) for it.
g. When this is done, click OK.
Method 3: Run System File Checker (SFC) scan to fix any corrupt system files. To do this, follow the steps mentioned in the link:

I bought a laptop with Windows 7 and I didn't have a problem until I had installed Windows 10 on it. I'm glad that I have some experience on the computers because I was stomped making minor C# apps to fix the commonly known problems.
To sum it all up in a bag, Thanks for this bro, worked like a charm and I never even thought of using that command!

Oddly enough...this Diagnostics issue doesn't appear to be as we have thought. My computer was unable to connect to the internet even after connecting an ethernet cable. When I attempted to resolve it. I received the error that said the diagnostics policy service is not running. I attempted to start the diagnostic policy service per all of the previous instructions over the past 3 years to no avail. As I was casually looking at all of my network adapters I noticed that my main wifi adapter was disabled...matter of fact...all of my network adapters were disabled after a recent Windows update. I right clicked on my wifi adapter and selected "Update Driver", and it reactivated it. My computer was then able to see my wireless router, and I was able to connect to the internet. So, after reading all of the way to start the Diagnostic Policy Svce...I went back to the service and tried to initiate it again after I was successfully connected to the internet...and guess what....it still didn't work...yet i'm able to successfully connect to the internet...so all of the folks that recommended a system install didn't mention that it appears to me..a non geek that the computer didn't even need that service to successfully operate to the internet. I hope someone is able to find this useful
Well, if that doesnt work, search files for your wireless LAN driver and unninstall your version in device manager, then install version from files, if there is no such file, than start the recovery disk and refresh the computer from settings (Windows 8), on Windows 7 you need to backup every thing that you need, and than basically go back to factory settings, using recovery disk, of course.
