Games problem.

[joffy]

I'm having problems running games.
I can play STALKER: Call of Pripyat fine, but ARMA 2 with latest patch, will run for a minute, then freeze, desktop comes up, but I can still hear the game running, so ALT+TAB, but can not click the games icon in task bar so have to close it in task manager. It will run fine in windowed mode.

Just installed the Just Cause demo and it's doing exactly the same thing! Also runs fine in windowed mode.
Nothing is over clocked, temps look fine.

My specs are; Q9550, 4GB RAM, 5850 with latest ATI driver, Corsair 530w PSU. Win7 x64. DX11.

Any ideas please?

UPDATE: The Just Cause 2 demo has just crashed like before after a while playing in windowed mode , proceeded with a "display driver has stopped responding" error message.

Thanks. Uninstalled drivers, ran the Just Cause 2 benchmark, froze as before.
Do I need to install older directx? Will try the ASUS gfx driver next.

 

[joffy]

Well cleaned all trace of ATI drivers, installed ASUS version and runs ok now!

DOH! Playing ARMA 2 fine for a while but then it crashed same as before. It's weird cause when I get task manager up it says it still running ok.
GRRRRR!!! Just Cause 2 demo crashed at start now

Try formatting.

Think I'll have too
Just browsing the Tesco site in Firefox and the display driver error came up!

Finally got round to formatting and reinstalling Win7, tried new and older ATI drivers but problem remains.
Been playing The Hunter, which either runs ok, or will freeze 30 secs into the game, blank screen then recovers, or will then sometimes quit to desktop with the "Display driver amdkmdap stopped responding and has successfully recovered." message.

GPU temps max at 71c, fan max at 30%.

So any ideas please?

 

[joffy]

Thanks. Nothing is overclocked. I'll try what you suggest now.
UPDATE; Seems the crashing only occurs with a certain stick of ram installed. Will run Memtest to make sure.

 

[joffy]

Memtest did not report any errors.

If the problem is only with Arma2 and other games work fine then maybe have a look on the Arma2 forums and do a bit of searching for others with the same problem as you?

It's all the games I have except for STALKER: CofP. Games seem ok with one of the sticks of ram. The other stick installed on it's own or with the other, games will crash. So will RMA with Crucial.
