Hi all, I'm new to these forums and could really do with some help please. I'm not new to Civ 5 and have had it running on multiple machines over the years, never with any problems. About a year ago I bought a new custom built machine and while the performance is brilliant on most games, for some reason Civ 5 just doesn't like running for very long before it, without warning, exits to desktop. Before many of you roll your eyes for yet another OP wanting to know why his game isn't working (I don't blame you, I'd probably do the same), I've spent hours looking into this and for the life of me can't figure it out. But what I can say is that nothing anyone has suggested so far has made any difference. So again, please forgive me, but I would really appreciate the help. The problem (described the best that I can): Game starts absolutely fine. After a variable amount of time (sometimes as little as 2 minutes, but never more than 10 - 20 minutes) the game freezes for about a second, then closes immediately. I never experience blue screens. My system specs are the following: - Intel i9-9900k (all core OC @5Ghz) - Nvidia 2080ti (driver version 441.12) - 2TB Samsung 970 EVO - 32GB RAM - Windows 10 Pro 64 bit (version 1903, build 18362.535). Peripherals: - Samsung 4k TV (via HDMI) - LG 1080 monitor (via HDMI) - Logitech G19 - Logitech Z Cinema - HyperX Cloud Revolver S (connected via a Sennheiser 3D G4ME1 adapter) - Razer Mamba Tournament Edition I did wonder if any of my drivers weren't working correctly, but I've installed the latest versions of all drivers for peripherals. It's worth noting that I've had all these same peripherals working with the game on my old machine, so I don't think that they are the problem. Things I've tried: - Updating my graphics drivers (they're not the latest right now, but I really don't see that it will make a difference at this point). - Reinstalled Windows. - Tried disabling DEP for the game, though Windows won't let me. - Tried DX versions 9, 11 and Touch for the game, all of which result in the same. - Disabling my over clock configuration. - Windowed mode and full screen. - Disabling VSync and GPU Texture Decode. - Manually reinstalling required versions of DX. - Running Advanced System Repair (which never reports any problems). - Verified the integrity of the game files via Steam. - Running as Admin and in compatibility mode for Windows 8. There are probably something that I've tried but missed off the list (apologies). It's also worth noting that my old machine is running Windows version 1803, as are my friends that play the game. Whereas this machine is currently running 1903, it was 1809 which also didn't work. Could this be the problem? Annoyingly when I reinstalled Windows the version it installed was 1809 so I couldn't get back beyond this to check myself. I do not run mods so the game shouldn't have anything interfering with it. I've checked the Event Viewer which shows that the game crashed with the following: Faulting application name: CivilizationV_DX11.exe, version: 188.8.131.529, time stamp: 0x546cd0a8 Faulting module name: CivilizationV_DX11.exe, version: 184.108.40.2069, time stamp: 0x546cd0a8 Exception code: 0xc0000005 Fault offset: 0x002ba03e Faulting process ID: 0x6b3c Faulting application start time: 0x01d5be47c7950302 Faulting application path: C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization V\CivilizationV_DX11.exe Faulting module path: C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization V\CivilizationV_DX11.exe Report ID: 3e98c29f-2399-4f7f-8cc7-ffc5702923b8 Faulting package full name: Faulting package-relative application ID: I've also had a look at the dump file in the Civ 5 directory which shows the "Exception Information" to be the following: "The thread tried to read from or write to a virtual address for which it does not have the appropriate access." Does this point towards an issue with RAM? I've not got round to scanning the RAM yet, but had assumed it was probably alright due to everything else (e.g. SQL Server, Visual Studio, other far more demanding games) running perfectly fine. I've attached a DxDiag file just in case anyone wants to have a look. Many thanks in advance.
