hd 3450 not recognised by my pc

Specs: Windows XP HOme, P4 2.66ghz, 2g Ram
I have recently purchased a Club 3D Ati Radeon HD 3450 but my pc doesn't detect it. My computer is a Dell Dimension 4600. I have also upgraded the PSU to a corsair 430w.

The GFX card I have removed is a ATI Rage 128 Pro Ultra GL AGPC.

Any help on this matter would be greatly appreciated.

430w is not sufficient.
A minimum 550w PSU is required for the Radeon HD 3450.

Also, you must install the card manufacturer's driver package.
If you didn't get a driver CD with your card, you can download the driver package from AMD: http://support.amd.com/us/gpudownlo...

The HD 3450 is a very low end entry level card. I hope you didn't pay much for it? Tom's Hardware has it rated at 23.1W under full load so I doubt the power supply is the problem. In fact, unless your old PSU was bad, there was no reason to upgrade to the Corsair 430W, 250W would have been more than sufficient.


And from the following article: "When it comes to power consumption the ATI Radeon HD 3450 looked pretty good across the board and was the lowest card that we have ever tested on this system. At full load the entire system consumed 142W , which is impressive to say the least"


Make sure the card is fully seated in the slot. Are you getting any display at all or just a blank screen? Did you upgrade the PSU & the card at the same time? Are you sure the PSU is connected correctly? Are you hearing any beeps?
