Good day , all you smart people.
So I bought a second hand G75VW....
i7-3610qm
Gtx670m

I installed a SSD(brand new) and 16gb ram(brand new)
System started fine and I installed Windows 10 on first system restart screen didn't come on milky black but heard windows tune. After that screen has not come on since.
However I hooked up an external screen and found there is a code 24 on the gtx.
Went through forums and tried various things updated bios , went back to windows 7 .... Anything and everything I found.
I have a feeling that the gtx is dead , can anyone confirm my diagnosis?
Thank you in advance
