2nd GPU not detected anymore

First time posting here, so sorry if it's in the wrong section... Last night I was transfering my PC from my HAFX to the HAFXB (technically a downgrade, but i'm kinda tired of lugging that thing around for LAN) and when i started the PC up, everything seemed ok, except that SLI isn't working anymore... 2nd GPU is not detected at all.

I've tried swapping GPUs to see if one of them is faulty... THey both work just fine when they on the primary PCIE slot.

I swapped the SLI bridge. No difference.

I removed and reseated the GPUs. No difference.

I reinstalled the drivers. Nothing. Uninstalled, DriverSweeper, Resintalled. Nothing.

I'm fearing that the 2nd PCIE slot is dead. I'm not even sure if it should work, but I tried seating only 1 GPU and on the 2nd PCIE, the PC boots up fine (as in no error beeping), but no image on the Monitor. If it is dead, I'm assuming there's not much I can do correct? It was quite weird as well, cause at some point when I put monitor 1 on GPU 1 and monitor 2 on GPU 2, NVCP placed both Monitors on the 1st GPU (in that little image) but no image on monitor2. Anything else I can try to get it to work?

If not, then it raises another question... I have an i5 2500k which doesn't support PCIE 3.0, so obviously if I get a Z77 Board, it won't utilize the PCIE 3.0... Anything else I'll be missing out? If I'm not mistaken, I won't be able to use USB 3.0 as well no? Might be wrong on this one though...

And of course, what's a good high-end Mobo for Z77  ranging from 150-250$ (OK i've been browsing, looking for some, noticed all these high-end ones like AsRock Extreme4 / 6 or Asus Maximus, etc, they have very few USB ports =[ I have tons of peripherals though

Any help is greatly appreciated.

well maybe it can be some setting in the bios..?

but if you put a single card in the second slot, and it wont give image, then i am affraid its dead..

if you connected the power cables etc correctley..

pci-e 3.0 is a useless feuture cause  youre cpu, 2500K doesn´t support it..

only ivy bridge cpu's do..

if you want a good z77 mobo, take a look at the Msi Z77Mpower alias the big bang

but to me it sounds a bit strange if you only chanced the case arround the build..

maybe a  the second slot configures wron in the bios, try to reset the bios, by disconnection the psu and take out the battery., for a few seconds then put it all back

 

I'm sorry, I should have also specified that I did try a BIOS reset. 

As for the Mobo you suggested, i took a look at it, i'm not sure the 212EVO will fit on the CPU. The heatsinks on it are quite bulky... =[ I've kept in my wishlist on Newegg.

Thanks :)

why it shouldent fit?

is youre cpu cooler bigger then this?

those big air coolers will fitt fine :)

I suppose then it'll fit, haha. Looks kinda cramped around the CPU.

Also, what about the Asus Sabertooth? Is it any better?

Can't edit... I'm just gonna go with the MSI MPOWER, thanks ^^

haha good choise ofc :) the sabbertooth is nothing better, i think eaven the Mpower is better,

the sabbertooth is only bad for youre bank acount :P

Ya, haha. I love the fact that the MSI is HAND-TESTED before they send it. Gives me assurance that the Mobo is gonna work 100%. I really like the features on it.

Thanks for showing me this mobo, i love it and can't wait to install it in my PC. I'll get an ivy bridge CPU later on, but atm i'm quite content with the i5 2500k. I'm not too worried about the PCIE3

let me know what you think of it once installed :)

I just finished installing and i love it. I haven't even started Overclocking... but everything is much better. 2nd GPU is detected from the get go.

Really happy. Thanks a lot! :D

I´m Realy happy to read that.

Ofc i knew you would be happy with this board. ☺

cause this girl knows what she likes, just quality haha :p

Msi Z77 Mpower is just quality, and also nice looking.

to bad msi didnt make a amd board about bigbang series :(

Have fun  :D

p.s. This topic is useless without pictures ;)

I'll post some up when I get the chance :D Looks really nice in the HAF-XB :D
