Hello, I was hesitant to post here, but I've searched for hours and asked as many people as I could for answers to no avail, so here I am =). This is a bit long, but that's because I'm trying to be very specific. I just reinstalled DayZ after quite some time having not played it. I reinstalled both ARMA 2 and OA on Steam, then installed DayZ on steam. I ran ARMA 2 once, then OA once. I then went through the process of installing the Beta Patch and installed Dayz Commander (which I am now using since it seems more user-friendly than running DayZ on Steam). I have updated to the latest version on DayZ Commander and I am able to join servers with no problems for the first 10-20 minutes. Here's the problem: After the first little bit on a server (ususally, as stated, around 10-20 minutes), The game crashes. It has done so 4 times. The first three times, the world became extremely glitchy. Everything (character, zombies, ground, etc.) started disappearing and reappearing, there was screen tearing, flashes of white, picture skewing, etc. The sounds also bugs out, with sporadic "pops" and crackles. I have two monitors and keep mumble open on the second monitor. When this problem occurs, Mumble crashes, first just disconnected from server, then upon reconnection attempt, it says something about being "unable to read". If a browser is open, it also crashes. DayZ didn't actually CTD, but I was forced to close it. The fourth crash was exactly the same, except after a few seconds, DayZ DID CTD, stating "ARMA 2 OA" has stopped working. After all crashes, I was unable to to reopen any of the aforementioned programs, as they would appear glitchy and immediately crash ([program] has stopped working). Restarting my PC makes everything fine and I am able to use all programs normally again. If I attempt to play DayZ again, the problem repeats itself after a similar amount of time. I have tried verifying the game cache of both ARMA 2 and OA, as well as the DayZ mod itself on steam (not sure if that actually does anything), after which I re-open ARMA 2 and OA once each before trying to run DayZ again. I have updated my graphics drivers and DirectX drivers. I have also tried disabling as many processes as possible in the task manager and then running DayZ. I do not get this problem with other games. System Specs: 1TB HDD 8GB RAM AMD Phenom II X4 980 (Quad 3.7GHz) AMD Radeon HD 7850 Windows 7 Ultimate 64-bit Good cooling (Just clarifying that overheating is not the problem, since I saw a few people with that problem) Can't think of what else to include. If I'm missing anything, let me know. I would greatly appreciate any help at all. I'd really like to be able to play this game again with my friends. Thank you!
