My gtx 1080 wont work! help

[Mathias_11]

I just bought the gtx 1080 and i cant boot into the system it keeps saying loading operating system in a continuous loop, i upgraded from a msi 670, I have a tx 750 corsair power supply, z68Xpud3 motherboard 12 gb ram 2700k i7 intel sandy bridge 3.5 ghz clock speed, i have about 5 fans 1 250 mm some 120mm ones not totally sure 1 ssd samsung 256gb one sata 7,2 rpm 1tb, i think it might be the power supply but i am not sure, i wanted to make completely sure before i went ahead and bought a new power supply, i hope someone can help me i would really appreciate it! i am sitting with a 909 dollar graphics card and its completely useless 🙁

Try your old card. If it still works, it isn't the PSU because the 1080 is only 10W more demanding. And at boot, there's not much demand on the card anyway.

stuck in a boot loop doesn't sound like a power supply issue. I would try your old card first and see what happens. If it boots than you may want to go into the bios and make sure the PCIE settings are set right. it might be is some legacy mode.

''z68Xpud3 ' remember how these older boards had compatibility issue with 900 cards ???? looks like maybe the same thing with the new 10 series as well ??

you need to update your board to its latest bios for newer card support if not it maybe a no go if theres nothing wrong with the card

one more thing of concern as well ''(When updating from legacy to UEFI, use only the utility attached to your BIOS file) ''


these cards need full uefi bios to work correctly ??


[don't know if you got a rev1 or 3 board ?/]

hopefully you not SOL on any new cards over the 700 series

I have a feeling that it needs a UEFI bios to properly boot. Newest bios on the motherboard might have a bypass for this with some legacy mode or something. The 900s had a issue with this too.

one guy with that board and a 900 card did the bios and still not not work so for the heck of it he put the card in the boards 8x slot and he claimed it worked in it fine just for some reason not in the x16 slot ???
.1 x PCI Express x16 slot, running at x8 (PCIEX8)

I tried upgrading to UEFI bios it said bios id check error my 670 works fine, i also tried putting my 1080 in a 8x slot doesnt work, i have the f10 version, i have no idea what to do 🙁

well unless you can test the card in a modern computer to insure it works like said just may not be compatible with your board at all

that seems to be the push these days with thing ''get folks off theer good old stuff'' force them on to the new . dropping compatibility os support ect.......

I figure this time in 2 yerars it will be win-10 or nothing anything less then a skylake a no go if you what to use there new you will have all new

anyway with out testing the card to insure it just not a lemon you just don't know just the way it is with the new cards and some older boards as well

use to be you bought hardware to do and support your needs now you buy to support them and there needs
