Windows 7’s blue screen at ntoskrnl.exe+0x6F980

Posted on

QUESTION :

So I got my hands on a relative’s PC, which started this week to repeatedly crash from blue screen (Error : “Stop f4”). The system would crash when programs where loaded, without any apparent logic.

To try to find the cause, I followed those steps :

  • I checked the RAM’s status with memtest, no error. There are two of them, I tried to unplug each one and see the result : still crashing.

  • I made a chkdsk from Win7 install CD and it repaired quite a few errors. Now the system seems less unstable, so far I can run user programs without trouble, however using some of windows functionalities still causes the blue screens.

  • I tried to use the “Repair bad sectors” tool from the hard-drive’s property panel. But it always crashes at the same progression percentage, soon after the analysis starts.

  • I activated the minidump generation and downloaded BlueScreenView and it seems the crashes always happen at ntoskrnl.exe+0x6F980. Alternatively are also mentioned once cdrom.sys and volmgrx.sys.

Minidump summaries :

I’d like ideas of what step I could take next !

Thanks in advance.

ANSWER :

It turned out that updating the harddrive drivers somehow fixed the problem.
