Is there a solution to my specific problem, or should do a fact. reset

[Lunar Locket]

I have a Windows 7, 64-bit Dell computer.
One day, while going through some un-wanted programs and un-installing them, my theme suddenly changed from aero to basic theme. From there on, everything went horribly wrong; my audio and video ceased to work(they work in safe mode), Microsoft Security Essentials, Dell Webcam Central and Audio FX Engine have been un-installed without my consent, Sometimes it wont even start up in normal mode(I log in but it stays on the loading screen),windows explorer wont work, I can't go into programs such as "Services" for it says I have my theme will start in aero in normal mode and then switch after a few minutes, It states on multiple accounts when I want to open something "Error Message: Not enough storage is available to complete this operation" One along the lines sof,"You do not have the authority to access memory" and recently a Windows 32 message saying,"This service cannot accept control messages at this time".I can no longer rate my computer, my drivers seemed to un-install and I am at my wits end. I've seen multiple reports of Aero theme automatically switching to basic after a minutes of login, yet no solution(working solution) was provided. Doing a Please advise me on what to do. As I'm sure you've noticed, I'm not the brightest person, please carefully explain each step.

It sounds like a reinstall is needed. F8 at power on will access the Dell PC Restore and allow restoring back to the factory condition. However, before you do that, backup (copy) all your user data to some other media such as CD's, USB flash drive or external hard drive as all data will be lost when you do the backup.

Lunar Locket, let's see if we can avoid a reinstall if you haven't already done one. It does sound like that may be the end result, but let's see. I would like you to do a few things for me, if you can. fireberd's recommendation is most likely the outcome of this but we will see if we can do it another way first.

Please fill out your System Specs​

   Information

Your System Specs will help us to help you, and doing it in this manner will make them available to all helpers in every post and keep us from hunting for them. We ask that you fill them out in as much detail as possible including Desktop or Laptop, Model number if it is an OEM computer and all components with the Manufacturer and Model number if possible.

If you will go to your last post and click the 'System Specs' in the bottom left of the post, you will find a link to update your system specs. Please fill those out in as much detail as possible. If you would like to know what we would like, you can click 'My System Specs' at the bottom left of this post to see mine. If you do not know what your components are, this will help you accomplish this task. http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html​

Next Open a elevated command prompt ( click start, type cmd in the search box, right click on the cmd entry and select run as administrator) in the black box that opens, copy/paste sfc /scannow. If you decide to type it, notice the space between the sfc and the /. It is a system file checker which will scan your system files and attempt to correct any missing or corrupt files. What we want are the results to say windows found no integrity violations. If it says files were found but could not be repaired, close the box, reboot and run it again, after opening the administrative command prompt. You may have to reboot and run it three times for it to repair all system files. If it can't repair them after 3 reboots, let us know.​

Next, click start, click control panel, click on add remove user accounts and create a new Administrative user account with a new user name. When that is done, reboot and log into the new user account and see if anything is different.​

If you can, follow this tutorial and upload the results with your next post http://www.sevenforums.com/bsod-help-support/96879-blue-screen-death-bsod-posting-instructions.html
