1) You moved from a DELL to a ACER - The LICENSE does NOT carry over!!!! OEM Licensed copies of Windows are ONLY SOLD WITH that hardware from THAT maker.
2) Because your using a 'illegal' (aka not genuine) copy of Windows, Windows automatically downgrades the performance, including blocking the use of DVDs and more.
3) Your solution is to back the Acer Hard Drive into the Acer, then simply download and install the 'game' you want onto the Acer
4) Your Dell Hard Drive will need to probably be 'factory reset' putting the computer back to the FIRST DAY you took it out of the box (yes you lose all your stuff) in order to 'fix' WIndows on it since now you tried to force it to support a different computer (ACER).
5) Windows 7 is hasn't been supported for YEARS now. You need to upgrade each system (if possible) to Windows 10 to be able to support current and future game titles. I believe the grace period may now OFFICIALLY be over from the 'free' upgrade, and you may have to bite the bullet and pay for a 'store bought' copy of Windows 10 or via windows.com (Microsoft's website). But so you know many programs and products (games) dropped Windows 7 / 8 Support .
I'm pretty sure Windows 7 still gets updates and is supposedly planed to till around 2020. !
To clarify the misunderstanding

Mainstream Support (i.e. You me, every consumer whom bought a computer ) January 13, 2015
Extended Support (which your referring to) is CORPORATE Contractual support with Microsoft (like Ford, Chase, UnitedAirlines, etc.) that brings up a 'problem' with Windows 7, they will send out a update for ALL Windows 7 machines as a 'byproduct. They are NOT looking for 'fix' things for Windows 7 or 8. So if you call Microsoft right now and demand help with your issue (which you could do) outlined here, they will refuse you and tell you to upgrade to a SUPPORTED OS.
Second to that I was meaning, and sorry it wasn't clear, that games, programs (STEAM, Chrome, etc. ) all have dropped or are dropping 'support' for Windows 7 /8 when programming the games or programs. So you may 'want' to play a game or use a program but it doesn't "work" on your edition of Windows.

My Windows 7 copy on this hard drive has been verified and My Summer Car supports Windows 7. Sorry that I forgot to mention returning the OS to genuine. But still. Most of what I have works fine. By the way, I didn't really mark the drivers out the problem. I only updated the graphics driver and the network adapters. I didn't want to risk downgrading any drivers. Thank you for helping me out guys!
As you have completely different hardware, you should remove ALL devices in Device manager NOT part of the new system. Basically you confused Windows on where it is, and what it is working on and takes a while to fix all that. There is NUMEROUS other drivers (such as the Hard Drive I/O driver to 'read' and 'write' to HDD like 'reading' the game code to load the game), You should visit the ACER support page for your particular model, downloading all the drivers, THEN also the 'Assistant' software so it applies all the proper updates.
Again though, the problem comes up that CURRENT drivers are NOT for Windows 7, but Windows 10 and "Don't Work" in Windows 7 machines if you apply them. So again, a root cause of your problems today AND tomorrow is your on a OS that is NOT supported and will have further issues looking to fix such 'drastic' changes like you did to the system.
