![]() All of the drivers need to be manually installed separately after the Windows installation is complete. However, if you re-install Windows yourself then only half the job is done. PC makers also usually have a way to factory reset the PC that sets everything up the same as at purchase. If the PC is built for you then they are usually pre-installed by the PC manufacturer. Those drivers come with the PC or new components when you buy them. This includes graphics, WiFi, sound, etc. But for more complex, non-standard and new components, the drivers are often not built in to Windows. Some components have been around for so long that simple/standard drivers are built into Windows, e.g. Drivers free Microsoft from having to research and understand the tens of thousands of different hardware components on the market and they protect hardware makers from having to reveal how their proprietary devices work. The component makers write the drivers for their devices. It may have been that someone re-installed Windows manually but forgot to install the all the extra drivers that the PC needs.ĭrivers are like interpreters that tell Windows how to communicate with hardware components. I'm not sure how the PC managed to be using the wrong, crappier graphics system by default. It is built into the main CPU and isn't on the same level as a separate dedicated graphics system, like your nVidia chip. It's got to the point where it is fine for most things but not really suitable for serious CAD or gaming. Intel graphics is generally awful but getting better. P.S., From what I've researched, you should be able to change the Dedicated Video Memory on a desktop PC under the "BIOS Settings" but laptop manufacturers usually don't include that function to save money, and due to limitations of the motherboard it's not that easy to upgrade a laptop's graphics card. Therefore, upgrading to Windows 10 might actually have an additional bonus which can hopefully solve a few more of your problems when using LDD, especially for laptop users. Recently, I upgraded to Windows 10 and the Dedicated Video Memory of the Intel Card was automatically modified to 128 MB, therefore meeting the basic requirements of LDD! Now, I can run LDD on either the Intel Card or the NVIDIA Card, which is good (although I still can't smoothly open larger files, but never mind). This improved things slightly and helped to satisfy my short-term needs, but I still had to find a long-term solution. Fortunately my laptop also had an NVIDIA Card (NVIDIA GeForce 840M) which was powerful enough to run LDD, so I switched to that one under the suggestion of the LDD Support Team. One of the basic system requirements of LDD is 128 MB of Dedicated Video Memory, and when my laptop was still using Windows 8.1 I only had 32 MB of Dedicated Video Memory (Intel HD Graphics 4400), therefore causing all sorts of problems (all desktop PCs at my university had 64 MB on their Intel Cards, so mine was crazy bad!). (Windows-provided drivers sometimes are too generic.)įor me, upgrading my laptop to Windows 10 actually helped to solve more of my LDD problems. Try installing the ones provided by the constructor. ![]()
