Gigabyte mother board + GTX750ti + no bios access = black screen

[Hardway]

Hiya Tom's Hardware community,

I have read so many posts, tried a few things, read some more and throw in a few sleepless nights and I haven't progressed.

Machine specs basic overview.

Gigabyte Mother board. H77M-D3H
i7 intel 3.5GHz
64 Bit operating system
PSU 500watts
16GB ram
Graphics Card GTX750ti


Here's where I'm at
A couple of weeks back I upgraded the graphics card, installed latest Nvida drivers and uninstalled the HD4000 built in graphic drivers. New graphic card works great no real problems, except after the install the machine stopped quick starting. This slowly got to me and thought I would change a few settings.
Thought Id go into the BIOS and see what's going on and where I can tweak it.
Well I couldn't get access into the BIOS through any of the keys on start up (Del, F12 etc)
I remove the CMOS battery to reset the BIOS and I could perhaps could gain access to the BIOS. That didn't work either even after jumping it and or waiting a few hour before reinstalling the battery again.
Now the machine is starting and appears to be running ok as I get the GIGabyte Mother board screen but then the screen goes black and I still can't get access to the BIOS.
I feel there's a problem with the new graphics card talking with the mother board after I have reset the CMOS and as I previously uninstalled the driver for the built in graphics card I can't go past the black screen.

Any other thoughts on how I can move forward, its so frustrating when all I wanted to do was access the BIOS and change a few settings.

Thanks
Cain

Are you using a wireless keyboard?

Or if its USB is it plugged in to a USB3 port?

Funny that was almost going to add that detail in the first post.

USB keyboard plugged into the back Im not sure if it plugged into the USB3 port. I tried changing the USB port that the key board is plugged into but unfortunately at this point the PC is not recognising the hardware as it in a new port.
Wireless mouse mouse.

I have run in to the same problem at times,


1 are you using the HDMI port on video card ? and what are you using for monitor ?

looking at the board and its vrm's with out heat sinks make me wonder if they can handle to power needed for the pci-e slot for that card to run[??] and if so for how long with full load and a few hrs of gaming??

Have you tried testing with one stick of memory at a time?
What PSU do u have? Give it's details.
Can you check the GPU on any other PC?

''uninstalled the HD4000 built in graphic drivers''

I don't think you needed to do this when you put the card in the on chip should auto disable or be turned off in the bios by switching it to pci-e

I've put 3 different cards in this one playing around and never had to uninstall the intel driver and have not found a conflict issue

Well ive worked out how to fix the very painful problem.
I had to remove the Gtx card, access the BIOS and change the oprom setting to legacy. Refit the gtx card and install drivers.
Works great!!
After all the things tried, resetting the bios, upgrade the bios, reinstall windows 7 and many more things it works.
All came down to the boot settings easy really..... only when know what to do. Shame it wasnt in the destructions.

ya that is way too much to do for a card but it seems I have read that uefi bios had to change to legacy but that was more on prebuilts with windows 8

well at least you got it going but it do seem odd you had to do all that over a vid-card

You bet that was to much to do for a GC. One thing lead to another, stuff stopped working....etc.
It works and now have to catch up on work.
