New Area 51 issues. Help!

hey there!

So I've been having a lot off issues with my new Area 51 r2. Here's my story...

The first two weeks the system seemed great. I only had world of Warcraft install so all was good. I decided to put final fantasy 14 on it which is where I ran into my first issue. It wouldn't install multiple times with errors everywhere. When I finally got it on my hard drive, Windows would become unresponsive trying to open it. So I uninstalled it.

Next, while gaming, my monitor would cut out turning off then on. When this happens, the lights on the actual tower would turn off and on too.

Next, I installed Star Wars TOR, but the performance on the game was terrible regardless of the graphics settings. So I uninstalled it.

After this, my system would freeze on "shut down" when trying to turn it off. I would have to hold down the power button to turn it off. It doesn't do this offend but once is too much.

Next, world of Warcraft started to studded and lag at any graphical setting. This was very irritating because it's really the only game I play.

Alienware tech support ran many tests to see what was wrong but nothing came up on tests. They sent a tech out to replace my gpu.

This is the worst of it. The tech had no idea what to do with my system. We was forcibly prying the panel on my town to get to the gpu until I say him doing this and showed him how to open it. Then he was yanking on my gpu very hard until he realized it was still secured by screws. He then tried to push the new gpu into place with a lot of force, seeming to bend the mother board.  The new gpu has not fixed any of my issue and the panel does not fix flush anymore from the techs prying to get inside. He was very rough on my system and never grounded himself before working on my system.

Now I've had random shut downs and beeping while startup. It doesn't do this all the time but again, once is too many.

The new gpu seems to get hotter than my last one. The alien fx says this one is at 85 degrees plus while on world of Warcraft and my first one that came with the system never got over 65 degrees.

I'm still in contact with tech support, which have been helpful so far, but I am wondering what to expect next. I do NOT want that same tech coming back and working on my system again. He was completely unprofessional.

Help me out Alienware/Dell. This is my first experience outside of Apple. I just want to game :(
