All my games freeze and crash to desktop plz help

Problem Event Name: AppHangB1
Application Name: moh_spearhead.exe
A problem caused this program to stop interacting with Windows.


Well after looking on so many threads and forums i have still not found a solution to why my games seem to crash like after 10mins of play, even whats more strange i can be playing for over an hour sometimes and it will do the same again, its becoming very frustrating for me. I've read it could be either a hardware or software problem, all my drivers are up too date i think. I've done a memory diagnostic test did not find any errors. Another thread i was reading said it's Direct x related.
Had this problem with ati cards before, thinking of switching back to nvida because of personnel experiences, they seem more stable. I built my new computer myself back in January of this year, i am from the uk and would really appreciate some help please. I will post screen shots if needed, anymore information you need feel free to ask

My specs are as follows:

AMD Athlon II X4 640 Processor 3.0GHz
4GB DDR3 1600MHz
500 GB SATA III
PSU: OCZ 700 Watt
AMD Radeon HD 6790 (1GB)
Asus M5A78L-USB3
Speakers (High Definition Audio Device)
Operating System: Windows 7 Ultimate 64-bit SP1


My cpu temps at idle are 33c and when gaming i never see it go pass the 50 mark!
Gpu temps idle at 50c and when gaming i never seen it go over 65 mark, but i did a stress test while running a benchmark and it went as high as 72c!!

I've read many comments on threads that the hd 6790 is just not a very good card, i am looking into buying an alternative card (don't know if this will fix my problems) if anyone has any suggestions what would suit my system best, i play games like battlefield 3, skyrim, batman arkham city, crysis, some older games to like the old medal of honor games and call of duty games.

yes other games are.. modern warfare, call of duty 2, crysis warhead, medal of honor airborne, i've set them all to run in administrator and change there compatibility mode to windows xp service pack 2 to see if that makes any diffrence.

can you see the files i have uploaded?

You might have mentioned you had some blue screen crashes, as well...

I see event viewer errors related to your backups. What do you use to backup your system and data?

Your applications crashing only indicate the applications themselves are to blame. Have you tried uninstalling them and then installing them again?

You have some .net runtime related errors with old .net framework components. It appears to be version 2.0, which is included as part of the Windows 7 OS. You probably have Windows corruption present.

• If you are overclocking any hardware, please stop.
  
  
• Run Disk Check with both boxes checked for all HDDs and with Automatically fix file system errors checked for all SSDs. Post back your logs for the checks after finding them using Check Disk (chkdsk) - Read Event Viewer Log.
  For any drives that do not give the message:
  Windows has checked the file system and found no problems
  run disk check again as above. In other words, if it says:
  Windows has made corrections to the file system
  after running the disk check, run the disk check again.
  
  
• Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

Those should be good places to start. I will analyze your .dmp files if needed once I get feedback regarding the above.

Sometimes i use a usb external hdd to backup any files i need, but thats always unplugged most of the time from the computer, i use to overclock both my cpu and gpu but then set them back to default settings to see if it made any difference which it did not, i've just tried to run a Disk Check i ticked the two boxes and it comes up with the following message.. Windows can't check the disk while it's in use.. Do you want to check the hard disk errors the next time you start your computer? Schedule disk check. I have already run SFC/SCANNOW Command today and on it's 1st time it did not find any errors but will do another scan now and will let you know

Schedule the disk check, and let us know how that comes out, as well. I would also recommend that you

• Run the short and long tests with SeaTools.
  SeaTools for Windows
  
  SeaTools for DOS

to make sure the hard disk itself is working properly.

I did a check disk like u asked me but as you can see when i search for Chkdsk and click find next the log should have the Chkdsk tag if Check Disk is ran only from within Windows, but instead it says sumthing called Wininit don't know if there is a mistake and i ran another SFC /SCANNOW command and again did not find any errors, will give seatools i try tho thanks.
