Sapphire Radeon HD 7750 Driver (I think) Issues

[aez5]

I am trying to install a Sapphire Radeon HD 7750 1GB GDDR5 card onto my gf's Dell Studio 540 (specs listed below). I've done the following already:

1. Removed all old graphics card drivers
2. Booted with no graphics card in. Went to device manager and disabled integrated graphics. Shut down.
3. Inserted graphics card. Booted, plugged in only to the graphics card (via dvi) and got a standard display at a nice resolution.
4. Downloaded and installed AMD catalyst.
5. Checked device manager: the card is recognized.

This is where the problem comes in. When I try to boot, the windows logo comes up just fine, but once it finishes loading on that screen, instead of getting the log-in screen, I get a screen with a mouse pointer and either a bunch of fuzzy lines or just a black background. After about a minute, the usual Windows 7 "Please Wait" screen flashes for a second, and then the screen turns blue (no, it's not the BSOD, there is no text). I can boot into safe mode just fine, and get a display through the graphics card at a decent resolution and the device manager lists AMD Radeon HD 7700 series as the display adapter, so I'm fairly certain that this isn't a hardware problem. If I uninstall the AMD drivers from safe mode and reboot, everything works fine, and I get a display through the graphics card.

Please help.

Specs on the PC: Dell Studio 540, Windows 7 Home Premium 64 bit, Intel Core 2 Quad 2.33 GHz, 6 GB RAM

That's really not helpful... not at all the problem I'm having.

Well, I uninstalled all the old drivers off my old gpu on my old GPU(GT 620) then after it was all uninstalled, I swapped out the GPU, inserted the new one, note it took ten mins to respond for the first boot, I don't know why it happened, then I inserted the driver disk and poof done. I don't understand why you used the Intergrated GPU for uninstalling the drivers

Glad it worked for you; unfortunately, as you can tell, I haven't been so lucky. Do you have any suggestions?

I used the integrated to uninstall the old drivers because the old GPU was fried, hence the new one. It's not an issue of it taking a while to boot. It gets to the "Please Wait" screen and then goes blank. I've left it for quite a while with no changes.

Try re-installing all the drivers, if that dos not work, you may have a defective card.

Tried the BIOS update, as well as old drivers (CCC 13.1). Got the same results each way.

Any other ideas?

Maybe something is defective? I can't think of anything else besides the GPU/Mobo or PSU that could be the cause... Wait, what is your PSU Wattage?

It's 350w with 300 to the 12v. I know that the system requirements for the card call for at least 400w, but I've seen a number of reports online of it working with 300w or even 250w PSUs.

I have it working with a 220W psu, so something must be wrong with the driver
