Radeon HD 5750 recognized as Radeon R9 280X after reformat

I recently reformatted my desktop because it had been a couple years and was running poorly. I was running Windows 7 HP x64 before and installed it again afterward, so this is the same OS I was using before.

Since the reformat, Windows doesn't detect my ATI Radeon HD 5750. It defaults to a Standard VGA Grahpics Adaptor. I don't know if the VGA is coming from my motherboard (ASUS M4A78LT-M) or the graphics card itself, but I think it's the card.

Every attempt to identify my card returns the same wrong result. Windows Update, Catalyst, AMD autodetect, and GPU-Z all wrongly identify my card as a Radeon R9 280x (specifically, in the case of GPU-Z, as the XFX Double D R9 280X). Because ATI only allows drivers to be installed via the autodetect utility in Catalyst, I've been unable to find and manually install 5750 drivers. Allowing the system to install the 280x drivers causes Windows to lock up on reboot and requires a trip to safe mode to clean them back out.

I've gone through and installed the most current drivers for my motherboard. I'm also aware that my card is no longer supported by ATI, and have been using the Non-GCN Legacy version of Catalyst (though I've also tried current Catalyst and older versions from 2011). My video card was working fine before I reformatted and I haven't so much as opened my case, so it's not a question of having my hardware connected and seated correctly. It seems very unlikely that hardware would just happen to fail alongside a reformat.

I'm at my wits end on this and don't know what else to try. Any help would be greatly appreciated. Thanks!

Standart VGA graphics adapter is any GPU. It's referred to such because its stuck from the VGA era. Also that's the default Windows driver.

That's really weird. This shouldn't be happening. Unless 280x is 5750. Try reinstalling Windows. If that doesn't help, try the GPU on another computer.

Thank you for the response. Unfortunately, I've already tried reinstalling Windows a couple of times, and I don't really have another machine to test the GPU in unless I can convince my roommate to let me tinker with his desktop.

I did compare models back when I first ran GPU-Z, and the 280x is not a 5750. It does happen to be a rebranded HD 7970, which one of the older versions of Catalyst picked up, causing it to install HD 7xxx series drivers instead (to the same end, breaking Windows).
