ADR Definition: Advance Diagnostic and Repair this is where Agents perform tests on your computer Check the Hard Drive, Motherboard, Processors, RAM, Etc. to make sure that they are all running OK and not the root of the problem. If all of these tests pass then Geek Squad continues to test the software (Operating System) on you computer. Often Agents will find Viruses, Group Policy issues, and holes in your OS that require repair. When you perform a system restore this really only fixes any changes in the registry. However when you perform an operating system restore this erases all the data, pictures, programs, etc. from your computer and as far as software goes your OS will be like new. You may back up the data yourself however, if the original reason why an ADR was recommended was a virus issue it is possible that you will back up the virus with the files at the same time. Geek Squad does not back up any viruses with their data back ups. Agents will not immediately jump to the conclusion of an OS restore. First they will attempt to remove all the viruses, restore drivers, and fix group policies.
Reasons why your computer could be running slow:
Hardware: Bad Hard Drive, RAM, Processor or Motherboard. The last 2 are more expensive and difficult to fix. If this is the case I recommend a new computer/ getting it fixed under a GS Black Tie Protection (up to 3 years only includes Software fixes if Premium or Vispy) / Manufactures Warranty (1 year Hardware only). If it is a Bad HDD you need to get a new one and run the Operating System Disc's, or if its the ram buy some more and upgrade the amount you have for faster computer speeds.
Software: Viruses/ corrupted Operating System, or a Fragmented HDD. Quickest Easiest Fix for viruses and a corrupted OS is an OS restore. To start OS restore in HP hit Esc while it is booting and follow instructions from there. Make sure all the drivers (software that makes your computer work with hardware) have been installed properly or else your computer will not function properly. For a fragmented HDD in the start search bar type disc defragmenter and run.
I hope this helps I know it was long,
