hello all.

My PC has had some issues with the graphics card overheating before and it used to black screen / TDR error a lot. Its a 5 year old PC and i was kind of expecting the GPU to fail (nvidia 560Ti) and last weekend I think it finally gave way, as it crashed, the screen went pixellated, and then crashed. When i rebooted i had green lines all over my screen and pixelation. I took it as a sign and ordered a new graphics card.
Since I don't need anything super high end, I've installed a Sapphire Radeon RX 460. It was about the right sort of price for what I wanted. I've since taken out my old graphics card and i booted in safe mode to run display driver uninstaller and remove all my nvidia drivers to be safe.
I did so then installed my new graphics card drivers as normal.
All appears to be running fine, however one problem which is puzzelling me is the boot load screen which used to be a picture of my motherboard boot bios screen but now is just pixellated.
Has the driver uninstalled removed something i need for my motherboard? I'm very edgy around installing anything for motherboard / bios etc. as scared i'll do more damage than good by playing with anything bios related while in windows.
Otherwise, as far as i can tell, everything works fine? So i think the Graphics card replacement fixed my problem. I hope.
Any ideas appreciated, picture and specs attached: http://imgur.com/Cs7RGV6
