Contacted company and they informed me that i need to change my Bios from on-board to pci-e the problem i have no idea in Acer bios what to change it all Latin to me. can anyone tell me step by step how to change onboard to pci-e in bios....ty
So, are you able to see the BIOS screen? is it simply when windows starts that you encounter problems with the video?
If so, you could try either VGA mode or Safe mode at startup.
Then proceed to uninstall the graphics drivers for your on-board, and install the drivers for your new card.
Except I believe you will have already done so, since the instructions on the manual would have covered this.
Another option is to try to find updated drivers on-line.
