I just built a new system using an msi 760gm-p23 mobo and FX 6100 six core CPU. I have a 450W PSU that came with the case and 4GB DDR3 1333 RAM as well as the GTX 650. After my initial build it seemed like the system hung up booting but I got no signal from the video card or the onboard video so I couldn't tell. Initially I suspected faulty RAM but after getting some input from MSI I discovered that I had a grounding issue with the mobo and the case somewhere which I corrected. I tried to boot again and everything sounded like it was working fine but still no signal from either output source. Continuing to troubleshoot I removed the GPU and everything worked fine using the onboard video. I utilized this TIME to update drivers for all of my components and tried the GPU agian; same result as before. I'm wondering if this mobo doesn't support geforce cards (my old radeon 4650 works just fine) or if the GTX card draws too much power or if it's a different problem all together.

Edit: upon further examination the GTX says it's GDDR5, could this be the problem?The type of memory on the card isn't important, it's only addressed by the card itself so there are no compatibility issues with the system RAM or memory controller.
Have you got another system you could try the GTX 650 in? What exact power supply is it that you're using? Have you tried another power connector, if one is available?Not saying it's true here but in general the PSU's they include on a case purchase ain't usually the cat's meow...
Usually a generic Tier4 quality or lower.That's pretty much what I was getting at, whilst covering other bases to try and RULE out the card (as it's an MSI).The PSU was already installed and it's a Thermaltake case so I would imagine the PSU would be theirs as well. I do have the PSU from my old computer that I could install and try but I don't relish the thought of pulling the new one out and swapping them. I suppose it would be possible to PUT the 650 in my old build and see if it works there. I'm reasonable confident it's not the mobo since my old video card is working just fine in the same PCIe slot. As far as the power connecters are concerned, it requires a 6pin which my PSU didn't have but it came with an adapter to attach it to two disk drive power connecters which I used. I'm confused as to why if the 650 is the problem why would it prevent my onboard video from working?Quote from: bouncingturtle on June 10, 2013, 09:10:29 AM
