My configuration is:
- MB - Supermicro X9DR7-TF+ - chipset C602/X79 dual processor, 2X PCIe 3.0 16x, 4x PCIe 3.0 8x., 2x Intel 540 10Gbps Network Cards, BMC/IPMI w/Matrox card on board - disabled from jumper BIOS Legacy Mode only, v 3.0a (latest bioses MB and IPMI)
- CPU - 2x Intel Xeon E5 2650 v2, 2.6GHz
- Memory - 64GB DDR3 ECC Reg. - 4 x 16GB Samsung
- Samsung Pro 840 series 512GB SSD as system drive
- 8 x 3TB Samsung Enterprise SATA3 drives in RAID5 using onboard LSI SMC 2208
- Supermicro 1200W redundant SuperQuiet 4U Tower Case
- Nvidia Quadro K4000 GPU tested in both x16 slots
- Windows 7 Pro x64
After installing Windows (Nvidia out of the computer) the computer using onboard GPU, everything was wonderful. Computer was loading windows in maximum 50 seconds (all bunch of drivers and processes). Then, I installed the K4000 in one of the slots. I restarted without installing driver and the restart was normal. Then I installed the latest Nvidia Driver and the first restart was again normal. After loading the drivers and nvidia being fully installed, the computer stalls aproximately 20 minutes at Windows logo before loading all drivers. The keyboard seem locked in all this time. But after waiting 20 minutes windows finishes loading and everything is ok.
I tried to disable software the MB GPU, then hardware from jumper and use only K4000, I even reinstalled windows with MB GPU hardware disabled and Nvidia installed and the result is the same when the Nvidia drivers are loaded. I tried moving the card in the second x16 PCIe slot but no luck. I changed since the first installations 3 generations of drivers but nothing changed.
I use now hybernation to be sure I can start the computer faster but sometimes I have to restart to make updates...
Has anyone met this behaviour in a GPU? What might be the problem?

Thanks!
