thanks for reading! Upgrading from a nvidia 8600gs card to a 750ti and computer will get to starting windows screen and lock up, or if i cut power it will get to the start normal or safe black screen and freeze after a few seconds. the 30 sec auto timer will stop at 27 seconds. Always freezes a few seconds after seeing the gigabyte screen during boot up.

reverting to old card or on board graphics and it loads fine. I used @bios and updated my moab (ga f2a68hm-h) tried removing all nvidia graphics drivers before installing, and used system restore to undo that and tried installing with nvidia drivers on it.

I have defaulted bios settings and removed battery and tried to no avail. I cant figure out what the issue is.

Gigabyte AMD FM2+ A68H SATA 6Gb/s USB 3.0 mATX ATX DDR3 2133 NA Motherboards GA-F2A68HM-H

Crucial Ballistix Sport 8GB Kit (4GBx2) DDR3 1600 (PC3-12800) 240-Pin UDIMM Memory

AMD A4-7300 APU Dual Core Radeon CPU Processor HD8470D Graphics FM2 4000Mhz 65W 1MB

EVGA GeForce GTX 750Ti SC 2GB GDDR5 Graphics Card

Cooler Master 324w power supply


Not that I thought it would help but i did a clean install of windows as well. maybe a bad card
 


I am inclined to think that your PSU is not up to the task of powering the new video card. Coolermaster is not known as one of the better PSU makers.:bounce::(:pfff: I would suggest one in the 500-550 Watt range from tier 1 or 2 from this:

Good luck!
