After reading the other 2 threads on graphic cards not recognized, I'm still in a funk. I recently installed a Gigabyte Radeon 7750 Graphics card into my computer. The monitor seems to work fine, but running DirectX shows that the graphics card is unavailable. I used Drivesweeper to remove the old NVIDEA files, attempted to update my BIOS (See Below), and updated the driver for my card from the Gigabyte website.

AS for the BIOS. On Acer's website, M1641 was not on the list for available downloads, only the M1640. Heeding the warnings carefully, I decided to contact Acer's help desk. They directed me to Seneca since it was refurbished. Seneca told me to go to Acer because my computer was too old for them to help me.



I think I have attached everything that you needed.

I downloaded a driver from
GIGABYTE - Graphics Card - ATI - PCI Express Solution - Radeon HD 7000 series - GV-R775OC-1GI
Not sure if it's the same thing, but I will give your link a go.

Appears to be the same thing. After reinstall, still no recognition, same results.

Yup, looks like 250W. Who reason I got the card that I did was because a lot of sources said it won't need a power supply. Looks like I need to get that fixed too. Thank you.

Is any Power Supply above 400 suitable? Or are there things I need to look out for? I came across an Antec 450w Power Supply on Best Buy.

Purchased a Dynex 400w ATX PSU (Selection was limited). Still running into the same issue. Here is what I have done so far:

Installed Graphics card and it's driver
Drivesweeper on old NVIDEA drivers
Updated Graphic Card to latest driver
Installed 400w PSU

I didn't connect a direct power supply to the graphics card, only inserted it into the PCI (looking at videos of the 7750, I didn't see them connect anything, nor do I see on the card where I would connect anything anyway.
