Hello Vorbroker, Welcome to the Forum.
Why do think you need that BIOS update to install the video card?
Flashing the BIOS is serious business and an error can brick your computer. You should do this only if it is necessary and only if you clearly understand what you are doing.
I visited the Lenovo website and looked up the Ideapad Y710 and saw that there is only one BIOS available (v1.0). So I am concerned about where you got this new BIOS from. They are not mix and match. You must only use the BIOS for your model laptop!
Important: You need to check the specs on your laptop. Newer laptops have "Dual Graphics" capability. In addition to the video card there is also a integrated graphics processor, either on the motherboard, or built into the processor. You need to know if this is the case with your laptop, because if it is so you will need to install either the dual graphics drivers package from Lenovo, or do a more complicated dual install. Let us know what you've got. If there is only the graphics card in that laptop you should be able to install just the AMD/ATI drivers.
To install a new video card
it is very important to follow proper procedure, as follows: - Go to the ATI website and download the most current driver for your new card and save it to an easy to find location.
- Go into Start > Control Panel > Remove a Program and uninstall all programs for the video card. For ATI, select “ATI Catalyst Install Manager” and click on “Change”, then “Uninstall All Components”. Do not restart the computer at this time.
- Run DriverSweeper to uninstall all video remnants Guru3D - Driver Sweeper .
- Shut down computer and remove the battery.
- Remove the old ATI card, install the new ATI card. Make sure all auxiliary power connectors are plugged in. Some cards need 2. Read the manual.
- Reinstall the battery, plug in the power supply/charger, and boot the computer.
- When it reaches the desktop Windows will find new hardware and will install it's own WDDM1.1 driver. Let it. You will be asked to restart. Do it.
- Once back on the desktop you can now install the ATI driver package for your card.
Hope that helps.
