I have a DQ35JO intel motherboard and onboard graphics. I recently upgraded to 32 bit Windows 7. I decided to upgrade to graphics and purchased a GeForce 8440gs. Once installed I started the system and the new graphics card info was displayed. Then the system would not start windows and remained at the intel screen with 5A displayed in the lower right corner. I felt the board may bebad so I returned and replaced it with an upgraded mode. Same problem. after reading other blogs, I am apprhensive to try upgrading the bios and anything wlse. Any ideas would be greatly appreciated.
