GPU isn't recognized sometimes when booting.

Problem: My computer will only detect the video card about 25% of the time.

Symptoms: When I first turn on my computer if I hear all the fans going full blast I know the video card will not be detected so I have to keep rebooting till I hear the fans slow down. I know it's not a faulty video card because I exchanged it for a new one with the same symptoms.

Power Supply: CORSAIR CMPSU-750TX 750W
Mobo: M3A32-MVP Deluxe/WiFi-AP
GPU: Sapphire Radeon HD 6870

Any ideas on how to fix this?
BTW: I have latest firmware for Mobo

  1. Do you use HDMI or DVI?

    So if you reboot a few times it will work? Might be a motherboard or PSU problem. Go into BIOS and give me your +12v +5v and +3.3v readings.

    Do you have access to another power supply? Maybe a friend you can borrow one from?
  2. Do you have your intefrated GPU disabled? Like said above could be MOBO or PSU. You have a good PSU and all your cables that need to be pluged into the MOBO is correct? and GPU?

    This link might help or not but it is worth a shot Good luck.
