Why is Photoshop crashing my system?

Question

I used CS3 for many years and it was never, ever a problem.
My computer is new and it doesnt have a single problem running other applications, but when the new CC photoshop is open, i cannot do a single ther thing for more than two minutes.
There's no official way to file a support ticket with ADOBE at all, and that's infuriating.
I committed a year of this plan and that's a lot of money for a program that lags my entire system. It just makes everything freeze. i have to force shutdown my computer, and I hate doing that.
I use Photoshop for Second Life design and i have to have photoshop open while i have Second Life also open and with the new one, there's just no way. Is there a setting i can activate on this new PS that makes it less consuming on my processor and doesnt make my entire system crash? And is there no one i can contact if i want my money back?
Mostly, it's incredibly frustrating. I work from home and I work every single day, and this has almost put a screeching halt to my work, and therefore, my income.
Does anyone have any kind of help for me on this?

Answer 1

What money back?
You used Photoshop CS3 for years.  Presumably you got value from it.
You have a new computer, quite likely with an OS Photoshop CS3 was never designed to work with.  Does Adobe claim it should work?
Do you really think this is someone else's problem?  I imagine you will not get any support from Adobe.
All that said, I've been able to get Photoshop CS3 to work fine on Windows 8.1.  Perhaps if you'll be more forthcoming with details of your system someone might be able to help you to get it to work.
Go into Photoshop, choose Help - System Info, copy the results, and post it here.
