Dell Repairs Broke My Laptop

Well I don't know that posting here will do any good, but I have seen some similar stories and would like to add mine to the pool.

Long story short, Dell repairs broke my laptop. I have an Alienware A51m R2, which I sent in to Dell for repairs about a week ago (I'm out of warranty). The VGA fan was not responding and would speed up to 100% even when temps were in normal range. The noise made the computer practically unusable. So, I paid for the Dell express repair mail-in service, because I am a student and this is a really inopportune time for my main computer to not work. The repairs were quick and my computer was returned about a week after I sent it in.

As soon as I picked my laptop up and booted it up for the first time - no video. Well, that's interesting because I have never, ever had an issue with the graphics on this laptop. I called Dell's out of warranty technical support and was told that I would need to send the laptop in (again) for repairs and pay for it as well. I was told that this couldn't possibly be Dell's fault because this is a software issue, while my initial issue was hardware related, so it must be a coincidence. After doing some reading, it seems that not taking accountability for botched repairs is just part of Dell's common practice. I will not be paying more money to fix what Dell broke and play into the sunk cost fallacy. I asked to speak with a supervisor but I doubt that this call back, if it even happens, will fix my issue. My only idea now is to log a complaint with an agency, shell out a couple thousand more for a Lenovo or Acer, and never purchase from Dell again. If anyone has ideas for a nice non-Dell gaming laptop, I'd love to hear them.
