BSOD on Win 7 Ultimate...please help

Hi...ran into a BSOD loop when Win 7 Ultimate boots up. It boots up fine in safe mode. Here is the error from eventvwr. I tried memtest but it didn't report any errors. Also tried Windows Memory Diagnostics but no errors with that either.

"The computer has rebooted from a bugcheck. The bugcheck was: 0x00000050 (0xc05ed0e9, 0x00000000, 0x830a1d30, 0x00000009). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 042910-25584-01."

The relevant dmp files are attached.

Would greatly appreciate any assistance. Thanks.

You have so many different causes for these I have to think hardware. these currently show cv04bu,sys, cxcfa8ea.sys, your video driver (igdkmd32.sys,) etc.


I have to think there is a severe hardware problem. I would first look at memory (memtestx86 for 5 passes or more), if that passes I would run a system file check
(type cmd in search>right click and run as admin>sfc /scannow)

If that completes without error I would start thinking about a repair install.

If you are overclocking stop

Let us know if you need help

Thanks very much, Ken. Will look into and revert. Cheers

I ran memtest a few times, but it showed up no errors. I also ran sfc /scannow and it didn't report any errors. Ran Startup Repair via the installation disk, but no luck. I used BlueScreenView to view the dmp files and it's pointing to ntkrnlpa.exe in most cases. Other files it references in other dmp files are CXcfaAe8.sys and 0Cv0x4bu.sys.

I would greatly appreciate any further help on this...thanks in advance.

Resolved this in the end by re-installing display drivers from the laptop vendor's site and by removing a software called Dr.Web.
