I just purchased a Gigabyte 760 GTX GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125466

As well as a new 600W Corsair power supply. Installation of the power supply appears successful, as my system will boot with it and my old graphics card. However, with the new 760 hooked up I remain frozen at a HP splash screen telling me to hit ESC for a startup menu. Keyboard is unresponsive and I can't access the menu.

My processor is an AMD FX-6120 on an Angelica2 motherboard. (This was a prebuild computer purchased at Best Buy) the GPU I am trying to replace is a Radeon HD 7450.

I have attempted to install the latest nvidia drivers prior to installation of the GPU itself but since the card is not detected they will not install.

I am at a loss here, is it possible that my graphics card is not compatible with the motherboard itself?
 
Solution
The problem here is, it was a prebuilt computer and the OEM Angelica 2 motherboard. Most OEM motherboards come with system hardware locks and they don't allow even the slightest change in hardware. Your only solution now is to- change your motherboard. You can always go for a cheap one for around $50-70 http://www.newegg.com/Product/Product.aspx?Item=N82E16813157366

However, my other concern is your fx6120 is also a OEM cpu and only comes with factory prebuilt systems. As long as its socket AM3+, it should be compatible with your new motherboard but I just can't guarantee it 100%

This is the reason why its always better to build a custom built computer since they don't come with all these locks and restrictions

Yeah, I have definitely learned my lesson with this hastily made computer purchase...

Reading around, I see some people recommending altering BIOS settings to enable legacy support, but this seems to correlate with systems using windows 8, and I'm using 7. I don't see an option to enable legacy support in my BIOS at all.

This is the link to Angelica 2 BIOS settings page on HP's website: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=c03092621#N1164

I'm tempted to try disabling Slot Security on the PCI express slot, but from the description given it doesn't look like a lock on new hardware so much as a literal enabling/disabling of the slot.

I suppose a new motherboard might be the only option, I just have to come to terms with the fact that I'm basically building a new computer from scratch, haha. (Already bought a new case to accommodate the new GPU as well!)

My theory stands because I saw this case where a gtx680 didn't work on an OEM system that came with a gtx660. Now gtx660 is actually newer than the older gtx680. The exact thing happened and system got stuck right after bios post message. PSU wasn't an issue either

The lesson here is, OEM systems are bad for the community
