The semaphore timeout period has expired.

[Unconscious 0]

I have reformatted my computer and am currently trying to play DayZ from a fresh install. It worked brilliantly before I had reformatted, but now I'm a bit stumped as to what to do.

Whenever I try to play DayZ (via Six Launcher OR Day Z Commander), the loading of the server is interupted by the error message "the semaphore timeout period has expired", and I have to CTRL-ALT-DELETE the process. None of my other games do this, and I've reinstalled several times, it also worked absolutely fine before I reformatted the computer. (So it's not a hardware problem AFAIK)

Any suggestions as to what might be causing it?

Silly things that ruin games seem to include Framework 3.5/4.0 of you haven;t installed or updated that I might try it. That worked to solve a few unimaginable issues I was having with different games. Have no idea what "The semaphore timeout period has expired" means though.

Are you using wireless ?

Run chkdsk.

And when did you defrag last ?

Still suspect bad clusters on HDD

That's what I think too, but file fragmentation cannot be the cause since he just formated his hard drive.

Run chkdsk.

Thanks for the responses.

Chkdsk has been run several times - both from the elevated command prompt in the Windows Install Disk, and from within the OS during a restart. Found no errors. I just realized I have Microsoft .net Framework 4 installed, so I'll try getting rid of it and seeing what happens.

its possible your graphic drivers cant run the game http://www.sevenforums.com/general-discussion/246142-hard-drive-crashed-getting-semaphore-timeout-period-has-expired.html

That's quite unlikely I imagine, as I'm running the same drivers as before the format (where it worked perfectly). I'm running the latest GTX 280 drivers.

Still having some problems with this. I've tried updating all of my drivers - all of which are up to date. Day Z Commander won't even launch the game, it just hangs - Play WithSIX will launch it, but upon logging into the server it'll get stuck and after CTRL-ALT-DEL to desktop I see it's thrown up the Semaphore error.

I've updated all drivers, uninstalled .net 4 and installed .net 4.5, I've run Chkdsk and it's all coming back clear... Steam can play both Arma games without error, it's only affecting DAY Z. (Verifying the integrity is fine also)

I am also getting this issue. Have you managed to solve it?
