Hello. Lately, I have this problem. Whenever I launch Dota2 using my Nvidia card on Directx it freezes my laptop while loading the game's main menu's ui (Dota's ui uses Valve's Panorama Framework). There is slight cursor stutter and then complete freeze and the only option for me is to hard shutdown. First it happened once every 3rd time I launched Dota but it became progressively worse to the point that it now freezes every time. When I was able to get into the game itself it never froze there, only ever in menus. When I run the game on OpenGL it lets me further down into the menu but eventually, it freezes as well. The game works fine on my Integrated HD 4000 gpu. I tried to reinstall Dota, reinstall steam, update drivers and roll back to drivers (clean install) from September last year but nothing helped. I've played on this laptop using default DirectX for about 3 years and then using dx11 for another year without any problem until now (this started happening about two weeks ago). Other games are working fine, I've tried Fifa 17, CS:GO (CS:GO runs on the similar engine as Dota2 but is not using Panorama for UI) and played a lot of GW2 lately and there was never a problem. All of those games use the Nvidia card, I've checked. GPU's temperature seems ok-ish according to TechPowerUp GPU-Z (while playing GW2 and it was around 80 Celsius, 50+- C while idle). My Nvidia GPU is most likely faulty as it sometimes has trouble to load up at the startup, few times a week laptop fails to find it (it's not showing in Device Manager) but after reboot, it's there again. Also after those Dota2 freezes, it takes a couple of minutes for the computer to startup. Few times I got BSOD instead of the freeze and it said VIDEO_TDR_FAILURE, nvlddmkm.sys. Tried to troubleshoot it on Dota2 official forums and I got this response "It's just that DOTA uses 100% your hardware to have faster initial loading times " "It does not appear to be anything wrong with the os / software / dota configuration - it's just hardware fault [RenderSystem] ERROR! D3D call failed! hr = D3DERR_INVALIDCALL ( m_pD3DDevice->Reset( &m_PresentParameters ) ) i.e. card being "removed" and not recovering as it should" and then I was told that since it's most likely hardware issue so they can't help me further. So I wanted to ask if there is anything I can do? I know that my laptop is old and the GPU is probably faulty, but it still works fine in other games, is there something I can do to work in Dota2 again? Thanks for any help. My laptop spec Dell Inspiron 17R (7720) Nvidia Geforce 650m Intel HD 4000 Win10 So, a little update: After I installed the super old drivers (331.65, last one from Dell support site) first chance Windows had it actually automatically updated them to 369.09. They seem to work "the best" so far, Dota2 still freezes in the menu but it doesn't freeze the whole pc, just the game itself, which is at least bit of a progress I guess. Another update: Now it freezes in every game / program I run on Nvidia card not just Dota2 anymore. I tried stress testing GPU in hour-long test in OCCT 4.5.1 and there were no errors. Then I ran the power supply test and it stopped because the temperature on core 1 went over 85. After that I tried to also install OCCT 3.1.0 to test vram but my PC froze trying to launch the program and after that I was unable to open any version of OCCT - I tried to reinstall the 4.5.1 version to run further CPU/Power supply tests but now it says "couldn't initialize system configuration" and stops working. To run at least the vram test I downloaded MemtestG80 and run 2048 memory in default 50 passes and it found 0 errors.
