Windows 7DirectX
Win 7 comes with DirectX 11 installed by default. If your hardware does not support DirectX 11 crashes to desktop are likely to result. Check if your video card supports DirectX 11, and if not, make sure your PC has all the DLL files needed for your supported version of DirectX.
The Win 7 version of DirectX does not include all DirectX 9 DLL's, so if you do have hardware that supports DirectX 11 it may still be advisable to add the DirectX 9 runtime. Here's the link for it:
http://www.microsoft...&displaylang=enYou will not need to add the DirectX 9 DLL's if your PC had previously been running this version. When updates to later versions occur they do not remove DLL's. A clean install of DirectX 10 or 11 does not, however, contain all DLL's from earlier versions (which means you only get basic compatibility).
Note: Using the DirectX redistributable adds the missing DLL's but you must make sure you create a system restore point before installing them, just in case your system becomes unstable.
Do NOT attempt to uninstall DirectX 11 - this is guaranteed to cause system instability!Windows Operating Systems (all)ConflictsConflicts with drivers, start-up menu items, or other apps could cause issues.
Perform a
Clean Boot to make sure nothing else is getting in the way.
Create a new user & install your game under that new user's account.
Run
the System File Checker and
Disk Error CheckCheck that your BIOS and drivers are all up to date.
DirectX Error CheckingRun DxDiag, which is a diagnostic tool, to check for any problems.
Go to Start, select Run and type in "dxdiag'' (without the " surrounding it). If you are unsure about how to read the result and suspect there is a problem, save the log file and post the contents into a thread here - someone is sure to help.
Graphics CardsIf you are using nVidia graphics cards, check on the nVidia forums - there have been many reported issues with nVidia drivers this year.
Make sure you are using a supported video card. A lot of people reporting problems here are not.
Check the temperature of your video card - if its running too hot your PC will crash
(see Overheating).
Useful Utility:GPU-Z - Detailed information about your Graphics Card
Sound CardsAudio sampling rates can impact badly on performance. This causes problems with many games (from other game developers too) so should always be checked if your game isn't performing well.
This article shows how to
check your audio sampling and set it for optimal performance.
MemoryRAM requirements for games just tell you what memory is required for the game itself. When calculating whether your system has enough memory for Dragon Age you also need to take into account any other applications you may be running at the same time.
Useful Free Utilities: Autoruns - this checks what programs automatically run at startup.
If you have memory-hogging applications running in the background you may wish to temporarily disable some of them.
Process Explorer - A very detailed task manager showing information about running processes.
Memtest86 - Test your computer's RAM for memory errors.
Hardware/PerformanceOCCT - Stress test your CPU to check stability and temperatures. Provides useful info and graphs.
OverheatingOverheating causes crashes. To eliminate overheating of your graphics card and/or CPU as a cause for the game crashing you can install monitoring utilities.
RealTemp (for Intel Core processors) - Shows CPU & GPU Temperatures.
CoreTemp (for all other processors) - Shows CPU Temperature.
HWMonitor (not good with Intel Core processors, useful for others) - Shows temperatures, voltages and other information.
