My GPU is bricking my computer.

Last time on...dumb GPU issues...

I upgraded from a HIS H775F1GD Radeon HD 7750 to a XFX Black Edition Double D R9 280, but the update left my computer unresponsive and unable to start. At first, I figured it was a monitor issue, as my PSU didn't have enough power to supply the card and as such, it wouldn't be functional.

I have since taken the advice in the topic by buying a new PSU, a Corsair CX750, which should be more than sufficient to power the card and also provides me the 6+2 PCI-E connectors that I need. I also have since updated my BIOS and also uninstalled all old drivers in favor of the new ones.

/flashback

Now, there's a new issue. Even with the new drivers, BIOS, and PSU, the GPU is still a problem. After hours of trials and tribulations, I learned that the very act of plugging the 6 and 6+2 connectors into the video card will make my computer come to a full stop. If I turn on the computer with these connectors in, the motherboard will light up, I'll see the logo for the motherboard, and everything will seem fine and dandy until I come to the realization that the computer is not turning on. No startup screen, no password screen, not even the Windows logo - just black. I didn't even hear the initial beep from the motherboard signifying that everything is green.

And even once I remove the video card and its power connectors, the computer will still refuse to turn on. Only when I go into my Repair and Diagnostic menu and rollback my computer will it be fine, but the moment I plug my power connectors into the GPU, my computer will brick again.

So what's going on? Am I doing something wrong, or do I have a bad card?

Thanks!

Sorry, how do I go about doing this? I've never done this before (Which might be part of the problem...)

Here's a screenshot of my BIOS menu:

Alright, I don't know what I did, but my computer has finally accepted the new card into its life and will actually turn on with it plugged in.

However, how it refuses to acknowledge that it's there, and according to my computer, it's still using onboard graphics. Good lord, my computer is resistant to this thing.

EDIT: Okay, I STILL have no clue what I did, but my computer seems to have fixed itself. Everything's now operational, including the card.

I'll at least list my steps for anybody in the future who may have the same problems:

1.) 6 pin connectors don't work with 8 pin connectors, as it turns out.
2.) Repair diagnostic works wonder if your computer bricks through the use of the GPU for some reason.
3.) I deleted NVIDIA Physx and all of the AMD Drivers. That is, I did more than uninstall the Catalyst stuff - I went into my C:\AMD\ files and deleted the folders there, also.
4.) I redownloaded ONLY the driver I needed from the website. I checked Catalyst to make sure it was updated.

The last few steps make sense, but I still don't know why my card no longer bricks my computer. I literally did nothing to fix it - it just started working on its own.

Also of note:

1.) My MOBO STILL doesn't beep on startup.
2.) There's no Windows logo on startup.

Neither is a big deal, but they've both vanished for some reason.

Admirable


Ah, I'm glad that you can game now!

I hope this issue doesn't reccur anymore, and happy gaming :)
