I have just built two systems based on Gigabyte GA-B75M-D3H mobos using I5 processors & 8GB ram running Win 7 (64bit). As these are intended as low end CAD workstations using Solidworks 2013 I also fitted Nvidia Quatro 600 Graphics cards.
The newly built machines run fine when only using the mobos integrated video (Quatro 600 cards NOT installed).
When the Quatro 600 cards are installed the machine boots as far as the BIOS splash screen and then locks up - no response to any inputs. Tried disableing onboard video but get same result - then had to clear the BIOS and return to factory default to get them to boot once more after removing the Quatro 600 cards.
Anyone experienced the same issues or have any ideas of what I could try next please?
