Start with this

SFC /SCANNOW Command - System File Checker.

Please fill in your specs

System Info - See Your System Specs

Make sure you have up to date video drivers, and I would recommend scanning for malware

I have done SFC / SCANNOW, but when running the systeminfo error message 0xc000007b

Did you

Code:

CHKDSK /F

yet?

Please upload the results of the log file created the System File Checker, and this may be helpful - Troubleshooting Explorer.exe Crashing Issues

this Dump file ..

No, read Option Three of this tutorial which you followed earlier - SFC /SCANNOW Command - System File Checker

The dump file is a few months old so the findings are most likely going to be invalid now, but I'll have a look just as a matter of interest.

Code:

BugCheck 1000007E, {c0000005, 98d3182a, 8b983308, 8b982ee0}

Probably caused by : CHDRT32.sys ( CHDRT32+11f82a )

Code:

8b983308 -- (.exr 0xffffffff8b983308)
ExceptionAddress: 98d3182a (CHDRT32+0x0011f82a)
   ExceptionCode: c0000005 (Access violation)
  ExceptionFlags: 00000000
NumberParameters: 2
   Parameter[0]: 00000000
   Parameter[1]: 00000004

Code:

It seems that your Conexant High Definition SmartAudio driver is causing problems, by not using pointers properly, leading to access violation exceptions which do not have the appropriate exception handler. I would suggest checking for any updates from here - Conexant - Support

Code:
