Windows 7: Having trouble with ATI Radeon HD 2400

When I try to install the drivers, it doesn't detect my card.
It says an error occurred within the installation, and it asks me to view the log.
Here's the log:

Hello again, did you use Driver Sweeper to fully remove all old graphics drivers before installing the newer one?
I am asking for other to have a look too. You have me stumped.

Hi,Raw, are you sure that your card is seated properly on to your motherboard, if not, then please check it, actuallly turn off your machine and unplug it,
hope you are careful about touching the parts inside, anti static mat or wristband might be a safe thing to use, you don't want to fry any of your parts?
then remove the card and replace it and make sure you hear it click back in, and that it is nice and firm in that position etc,
then turn all back on and see if it was that, if nothing changes well at least we got that out of the way as being one of the causes. Please let me know when you have done this.

You have a desktop computer (the brand and model number would be helpful) with an Intel i3 processor. That means your "on-board" graphics is actually on the CPU. There is TTBOMK no "switch" for these graphics. As you say, these "onboard" graphics are supposed switch off when a video card is detected automatically.

A few thoughts and questions:

1. Does this card need an auxiliary power supply connection? The ones I looked at online did not.
2. The 2400s I looked at had one DVI and one VGA port. If you have, or can borrow, the cables - try connecting the monitor with another cable. VGA if you are currently using DVI.
3. Try installing the card in another PCIe x16 slot. (Note: I've found some 2400 cards that are PCI - not PCI-e. Do you know which type you have? What Brand and Model # is the card? This is not the same as the graphics engine/chip)
4. Can you borrow someone's (known working) graphics card to try in your computer?
5. Can you try to install your card in someone else's computer?

Let us know what you know.
