As I said I have a GM5478 which has an Intel G33 "Schroeder" Chipset MoBo in it,
Vista Home Premium 32-bit
Intel Core 2 Quad Q6600 Processor
Corsair TX-650 watts
4 gigs of ram
Vista Home Premium
Nvidia GTS 250 (currently)
I have tried upgrading to 2 different cards, one was the 550 TI and the other was a 560, after a full week of diagnostics, the man working on it handed me my deposit back and said "its not compatible"...
I assumed he meant my MoBo was incompatible, so I'm still gunna try a gtx 460, and maaaaybe an ATI but I dont like their Driver Problems...
Any suggestions for GPU's or possibly even why this may be happening?
What ATI driver problems are you referring to? Just had to ask.
So, your GTS 250 works just fine, but neither a 550Ti or 560 would work? That seems odd and there is no reason that either of those GPUs won't work. Was any explanation, other than what you posted, given?
Well, I've just ALWAYS loved the consistency of nvidia, even tho the price and detail could be worse than a lot of ATI's cards...
I will have to resort to ati if a 460, another try at a 550 TI or a 560 dont work
I had two different people install them, the first person knows wut hes doing but when i would start the pc it wouldnt even recognize the evga 550 ti,
the asus 560 was recognized immediately but wouldnt get to the login screen, we tried different versions of nvidias updates cuz i heard there were some problems but other than that this pro basically said the 560 was incompatible with my setup, which is so vague its ridiculous
but my mobo in this gm5478 is from like 08 so, i dunno?
Well, I think you should update your BIOS from the manufacturer's website and see if GTX 460 1GB will work since you like nvidia (fanboy I can say , joke apologize). I'm just going to say good luck for you .
