Hello everyone,

Recently I bought a new motherboard along with a CPU and RAM and a new PSU, my PC specs are as follows:

Windows 7 Ultimate 64 bit
Gigabyte GTX 560 OC Windforce (Model Name: GV-N56GOC-1GI)
8 GB RAM Kingston HyperX 1333 MHz
Intel Core i5 3470 @3.2 GHz
Generic PSU 650 W (upgrading to CoolerMaster Extreme 2 725W in a few weeks)
ASUS P8-Z77V-LK

The trouble that I'm having is with the graphics card whenever its in slot 1.

I have read the instructions manual and it clearly states that if I'm running a single GPU configuration (which I am) then it should be in the first slot, the one closest to the CPU.

But whenever I put it in the first slot, the motherboard recognizes the GPU and the slot runs at x16 (checked through BIOS) which is supposed to be the correct indication (keep in mind that the PCIE slot supports PCIE 3.0 while my GPU is PCIE 2.0, although I am aware that its backwards compatible).

However as Windows loads, there is no Aero and FRAPS fails to initialize saying that it failed to initialize D3D9 (has to do with Direct X 9) and when I right click the desktop to open the NVIDIA Control Panel it says that I need to have an NVIDIA card installed for it to open, and I can't run any games, and when I open the Screen Resolution menu by rightclicking the desktop it just says standard VGA display or adapter or something along those lines. Also I'm running a dual screen setup, HDMI connection to a 24" screen at 1080p and VGA connection to a 17" screen at 1280x1024, only the smaller screen opens and there is no signal on the 1080p screen, although 1080p screen is set as primary. And yes I made sure of the connections, like no loose cables or everything, I never keep anything loose, everything is screwed tightly. And device manager detects the GPU as Standard VGA Adapter

Now here's the weird part, when I switch the GPU to the 2nd PCIE slot, the motherboard also detects it, although at x8, Windows loads, Aero is working, NVIDIA Control Panel detects the GTX 560, both monitors are working on their respective resolutions, device manager detects GTX 560, FRAPS is working and I can even play Splinter Cell: Blacklist all maxed out, with FXAA (no MSAA) at 1080p @40fps and haven't changed not a single option in the BIOS, all I did was just move the GPU to the second slot.

Now ofcourse I thought it was a faulty PCIE at first, so I sent it back to my dealer, he said he'll take a look at it and see if I screwed something up in the BIOS or if its truly faulty, I'm like alright fine. So what he did is just clear the CMOS and set the settings back to default on the BIOS and move back the GPU to slot 1 and he told me that I messed up alot of settings in the BIOS and some other bullsh*t just so he won't give me a brand new replacement. So I took it back home in hopes that the issue might be fixed, I plug my PC in, and back to the same problem with PCIE-1. I even looked at the BIOS and it still says it detects the GPU and its running at x16. Like didn't he even run the PC on some monitor of his and notice that there's no Aero and the graphics card is not detected? So I switched it back to PCIE-2 and its working fine.

Now the reasons that I want to fix the 1st PCIE slot even though the 2nd is working fine is that:

-I want to make sure that its not the motherboard causing this (faulty PCIE slot), and its either GPU,BIOS or maybe even the GeForce drivers or could be PSU for all I know, because if it turned out to be really the motherboard and not my "messing around" with the BIOS he's in for a good call and a brand new replacement, but I want to solve this with RMA as a last resort because I have alot of college work on my PC I can't afford losing it for more than a couple of days and because I might invest in an SLI setup but I won't do it knowing that the first slot isn't fully functioning.

-I got a new case and as with all new cases, the PSU is on the bottom instead of at the top of the case, and I was forced to let the fan be facing upwards towards the GPU instead of downwards because the PSU has a short ATX cable and if the fan was facing downwards, the cable wouldn't reach the mobo plug, while if it was facing upwards towards the ceiling of the case it would. And ofcourse the GPU has its fans facing the ground and the PSU, and there is like 38 mm between the GPU and PSU, so their fans are fighting for airflow intake for cooling and this would surely cause thermal issues when gaming, so I need to fix the first PCI-E slot to put a distance between the GPU and PSU, and I'm not sure if the new PSU I'm getting has longer cables.

So good folks of Tom's Hardware, any suggestion as what the problem could be and how to fix it?
Keep in mind that I don't have any spare parts laying around to swap out and test, but there's a GTX 550Ti on my younger brother's PC that I MAY be able to borrow for testing if need be.

Any information I might have missed out or logs or dxdiag or screenshots or whatever you might need, just ask and I'll give them to you. I just want to solve this problem once and for all.

Update:
I was gaming while monitoring the temps using HWMonitor and the card was reaching 100 degrees celsius under full load while playing Splinter Cell: Blacklist on 1080p at max settings and there was some sort of burning smell coming out of the case. The temps on the old case were 75-80 under full load

I can't afford another PSU right now and neither is the first PCI-E slot working (read the first post to see what's going on) so I can put some distance atleast between the GPU and the PSU fans, any help would be greatly appreciated as I'm running the risk of losing my GPU, as for gaming, I'm putting it on hold until I get this all sorted out.

3 days and no answer yet..where are you all?
