Dear Gazutoids,
Let us set right a "critical" service which might have been turned off. Follow this fix.
" Under start>search programs and files, type devmgmt.msc if still no go, do the following, under search programs and files type mmc /a and a console box would appear, under file menu choose add/remove snap in, under available snap in, choose device manager follow by add and if you're prompted to choose "snap in will always manage" choose local computer follow by next and hit ok to leave the console box" Courtesy: My Device manager is empty

Next try going to device manager and verify if it's is working.

regards,
sree

Dear Gazutoids,
Sorry that the above method did not fix! The other cause for a Blank Device Manager is a corrupted key in the Registry. Before i detail the steps to rectify (Thanks to Microsoft Help), kindly carefully read and follow this tutorial of SevenForums: Default File Type Associations - Restore

The above tutorial will help you IN CASE the steps outlined below are not followed to the letter. It helps you to restore the registry!

Now, to the actual steps;
1. Click Start-> Run->type in regedit.exe.


2. Locate the following: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

3. Now right-click on Enum and choose Permissions.


4. Click the Add button and type in Everyone and click OK. Check the Allow box next to Read for Everyone.
Now click Add again and type in System.
Check the Allow box next to Read and Full Control for System. It should look like this:
5. Both the check boxes under Allow should be selected when you highlight System.
Also be sure to click on the Advanced button after adding both users and selecting Reset permission entries on all child objects with entries shown here that apply to child objects.
Click OK.
Restart your computer now and check if the issue persists.

Dear Gazutroids,
You are the owner,right,but are you the Administrator? Checkout this tutorial : Built-in Administrator Account - Enable or Disable

best wishes,

Dear gazutoids,
when you install Win.7, you are by default NOT the Admin. You have to enable the 'Hidden Admin.account". That's a secret i share with you! That's why the tutorial reference.
