battlefield 4 crashing, after i have installed something new on my system

dbghelp.dll is a windows system file and shouldn't cause errors under normal circumstances.

I would recomment starting with scanning your harddrive(s) for errors using the built in Windows tool:

http://help.ea.com/en/article/how-do-i-run-chkdsk/

efterwards i would run the Windows System File Checker to test for errors with your Windows installation:

http://help.ea.com/en/article/how-do-i-run-the-system-file-checker/

when i ran the windows system file checker it said:

windows resource protection found corrupt files but was unable to fix some of them.

details are included in the CBS. log

You might want to try and reboot your computer in safe mode: http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 and try running the Windows File Checker a couple of more times to see if that helps. You might also want to look in the mentioned logfile to see what it's having problems with.

ive tried it in safe mode and still get the same thing. so i looked in the cbs. log and here is a few lines from it, seem to be the same line down the log.

Hi just to try and help out what windows are you on ?  

If your O/S is Win8 or Win 8,1 then you can run this next command / line in administrator command prompt. Sadly this does not work for win vista or 7 :/ It will restore the health of your PC and you dont lose anything .

dism.exe /online /cleanup-image /restorehealth ------- ONLY works for windows 8 and 8.1

 When its done reboot

i done them both and they all repaired and everything repaired succesfully but now im getting these messages
