Try this first: Isolate the USB hardware as the source of the issue One of the most common problems with Vive customers is related to the USB settings or setup. Since the tracking, positioning, buttons input and status of all the devices is sent to the computer via USB, a USB issue will lead to major problems with the overall Vive experience. Before proceeding with these steps, make sure of the following: All the cable connections have been verified and tightened. The link box has been properly connected, on its right order. Original USB provided cables are being used. HMD is receiving power. Customer is not using USB HUBs or USB concentrators. Vive USB is connected directly to the computer’s mainboard ports. Change port from 3.0 to 2.0 USB 2.0 is the most compatible interface on modern devices. USB 3.0 is faster, but is not always stable with configurations such as Vive. If the Link Box is currently connected to a USB 3.0 port, advise switching the connection to a USB 2.0 port instead. NOTE: For the best experience, connect the USB cables of Vive directly to the PC, instead of a USB Hub. and then this: Remove All SteamVR USB Devices The Vive system is composed of about 9 different USB drivers, including Bluetooth, controllers, camera, receivers and audio, among others. Due to different reasons, like software updates, change of connections, system updates or malfunction of a device, the USB drivers might get into conflict and reinstalling them is a good way to get everything back to its working state. Go to SteamVR > Settings > Developer. Click on Remove All SteamVR USB Devices. Once finished, the program will prompt a confirmation of the process. Disconnect the Link box AC Adapter and the Link box USB cable from the computer. Close SteamVR. Connect the AC Adapter back to the Link box and then connect the USB cable directly to the computer to a USB 2.0 port. Open SteamVR and check if all the devices all properly recognized, by going to SteamVR > Settings > USB > Refresh.These are the default drivers: Vive Link Box: · Hub · Hub Controller · Bluetooth Vive Headset: · Watchman Board · Camera · Audio Device · Main Board · Wireless Receiver 1 · Wireless Receiver 2 Note: This list includes the drivers of the devices directly connected to the computer by USB, as it is the HMD and Link box. Controllers and Base Stations are connected to the headset through Bluetooth and then to the computer, so these devices are not going to be visible on this list. If it's still not working, let me know and we'll try something a little more drastic. Thanks, -John C

Ah so it ended up being the linkbox in your case. They should be able to replace your linkbox for you if you contact them. Did you do that already? Irk26 has it right. You can reach them at www.vive.com/us/support/contactus Of course, change the "us" part to your appropriate country or just navigate to the site as Irk26 suggested. I can also continue to assist here if you prefer. Thanks, -John C

I'm afraid Brazil is out of our service area. Where did you originally purchase it? Thanks, -John C

It does seem like there's an issue with the HMD. You should contact your local support chat for an RMA if you haven't already. Thanks, -John C

I responded to your PM, let's figure this out. Thanks, -John C

Open up SteamVR application > click on SteamVR drop down menu > Select "Settings" > select "USB" and tell me what you see. On a working Vive, all of those items should be bright grey. If any of them are dark grey, that means there is probably an issue with the component. Thanks, -John C

I just ran a fresh install on my PC to test. It works fine. You're downloading from www.vive.com right? There's something going on your PC or your network which is preventing the download. The executable works... There's usually 5 components that show up in Add/Remove Programs. It should look like this:

We've gone through a number of software revisions since May. What version are you currently on? Are you running as administrator? Do you have all your anti-virus software disabled? Thanks, -John C

Okay so that's good. Anyone else have Kasperksy Total Security or similar products? Guys, what do you think about this issue? Is it anti-virus blocking the app or is there something else going on? Thanks, -John C

What troubleshooting have you tried? Definitely make sure your anti-virus is not interfering and that you're running as an administrator. Has it always not worked or just recently? If recently, when? Thanks, -John C

Thanks Snow, I'll look into this. -John C

Have you used the troubleshooting tool in settings? If you follow through the steps it will prompt you to general a report or log and send it to us. Please do that next and let me know when it's happened. Also, if you could PM me your email you're using with the Viveport account that would be awesome. Thank you, -John C

What about anti-virus or firewalls? You're on your own network or a corpnet? Thanks, -John C

What Vive software version do you have? Thanks, -John C

Thank you for the information! Glad you got your new headset and it's working. We'll have to see when you give the longer test run, but I'm remaining positive. Have a good weekend, everyone! -John C

As a last resort, you can try this method: https://support.steampowered.com/kb_article.php?s=3c5db199e026e5fefe1d54a6360b03f8&ref=2748-WEIK-9562 See if that works for you. Out of curiosity, what's your motherboard? Thanks, -John C

That's actually very interesting. I'm glad you were able to get it to work and perhaps this information will help others with similar hardware configurations. Thanks! -John C

Well, according to Nvidia's website, the 1050gpu is not considered by them to be "VR ready" https://www.nvidia.com/en-us/geforce/products/10series/geforce-gtx-1050/ Here is a current list of Nvidia's supported GPUs: https://www.geforce.com/hardware/technology/vr/supported-gpus And you can also run a VR ready test for your whole system from us: https://www.vive.com/us/support/category_howto/how-to-check-if-pc-meets-system-requirements.html I hope that answers your question, -John C

You should be downloading from www.vive.com Latest version is r1076 (as of 7/21/17). Make sure your anti-virus is disabled or has exceptions for Vive software. Make sure you are running as administrator when you install and launch the .exe Thank you, -John C

Please provide answers to the questions asked earlier by in this thread. It will be very helpful if we can get as much information as possible about your issue and the circumstances surrounding it. Thank you! -John C

Please keep this to our one thread: http://community.viveport.com/t5/Technical-Support/flashing-grey-screen/m-p/9430/highlight/true If you could also answer jagibson's questions regarding what you're experiencing and post in that thread too, that would be great. Thank you, -John C
