	I have a Nvidia GPU in my computer but yesterday I got a message that my computer can't find the GPU anymore, it just vanished!! I tried to restore my computer to an earlier date, but it didn't help. What can I do? ____________

	What exactly reports that the GPU isn't found anymore? The operating system, or BOINC? If BOINC, try to uninstall & reinstall the videocard drivers. It's possible that Windows got updated videocard drivers in and these lack --depending on brand of course-- CUDA, CAL, OpenCL and OpenGL components. ____________ Jord - BOINC FAQ Service - BOINC User Wiki Real is just a matter of perception.

	When I want to go to the Nvidia Configuration screen, the system tells me there's no GPU detected and when I go to my account here and open my computers, it shows no more GPU. I don't think it's a problem with boinc. ____________

	Could still be a problem with drivers. Try to clean them out first, using something like Driver Sweeper or Driver-Fusion. Then do the regulatory reboots. If Windows still doesn't detect the card upon return, it's dead. But in that case try to reseat it first. Check also for bulging capacitors, or burn marks. Oh, and one thing I found at one point in time when my GPU went missing was that the power-lead had come loose. Might be a thing to check. ;-) ____________ Jord - BOINC FAQ Service - BOINC User Wiki Real is just a matter of perception.

	Power lead is ok... Will try to clean the drivers out. Thanx Jord :) ____________

	Tried Driver Sweeper. First installed Java and then the Nvidia driver scanner couldn't find any GPU on my computer...Getting kinda desperate...Maybe there's a malfunction inside of my computer but it's a laptop, it's kind of hard to open it and look inside... ____________

	What make of laptop and GPU? And what happened when you tried to install the Nvidia driver ____________

	I tried to detect and install the driver on the Nvidia website but it couldn't find any GPU and it was here a few days ago! Could there be something wrong with the wires inside my computer? I know what to do inside a desktop but a laptop is a bit difficult for me... ____________

	If you right click "Computer" then click "properties" then select "Device Manager" what is displayed in the "Display adapters" drop down? This is mine ____________

	I tried that as well and my GPU doesn't show anymore. It only shows Intel (R) HD Graphics. ____________

	The problem is, laptops are so hard to repair. Don't know how to open it and work on the wires. Just tried to manually install a new driver, didn't work as well, the program couldn't find a compatible device. I really think it has something to do with the wiring. ____________

	Unlikely to be the "wiring" as the GPU on a laptop motherboard is jut a chip on the board there is no separate "wiring". Laptop motherboard not many "wires in sight" My laptop does not have Intel Graphics so if the GPU failed then I would get a blank screen. As you have the Intel graphics I am assuming you have something called "'Optimus Technology' developed by nVidia" This basically means for all normal functions the Intel chip displays the graphics. For all graphic intensive functions like HD video, gaming or crunching the Nvidia GPU takes over. With this set up from what I have read on the web it is possible for the Nvidia GPU to become " disabled". All I can suggest is to see if there is anyway to find a "disabled" GPU ____________

	I can't find it. It's like the GPU just vanished. Always get the same message: the driver cannot find any compatible hardware...Also looked for disabled hardware, nothing...Tried to restore my computer to an earlier date, also doesn't help. ____________

	Did you try to delete the Intel graphics driver and reboot and see if windows then picks up on your Nvidia? ____________ Extraordinary claims require Extraordinary proof.
