Guild Wars 2

Long story short.
I broke my old motherboard, and bought a new one same model and same graphics card, well the new one isn’t working (old ran game fine and at highest level)

In the middle of a discussion about getting it returned but need some hard core proof that it has failed/never worked, or a way to make it work.

Since Guild Wars 2 is the highest game i play this is a big test for the GPU.
So first issue is logging in http://imgur.com/Yn0TLlY that happens to all my characters
Second when i try to get in game I crash, on min settings it didn’t happen right away on max I don’t even get to see the screen.
When doing auto detect it is very low settings unlike my old on that was near high range.

My GPU is Nvidia Geforce 740m, running on a laptop. Reinstalled Windows 8 off a disc so fresh drivers.
Finally managed to get it updated to newest driver and not crash my computer constantly, or freeze up but the games will not run.

So did I do something wrong or is the seller at fault and the GPU was junk, I did talk to the seller and their response was

“Okay. I think the issue is the game. It worked okay in using it normally, but if you use it for gaming it can be a problem because this motherboard is not fit with it and I can’t cover it. New online game need a lot of power of gpu and it’s own big memories. This board is a used one and was cleaned and was reset for fit other laptop, but didn’t replaced new gpu for gaming. You’d better ask me if it would be good at game before your purchase. Gpu can’t be perfect as in new board. You should bought new one instead used or refurbished.”

Does that sound right?

Thanks in advance.

You flash your bios?
After that, you need to update every driver you can find pretty much, including sound and everything else.
Then try video card on low settings from it’s cp.
Check sound setup.
Still having issues at that point, running intel? CPU diagnostics from their site. AMD prolly does too. No CPU is perfect, but there is a threshold.
