I have a custom built machine with windows 7 ultimate.

  • Core2Duo 2.93Ghz
  • 12GB RAM
  • 500GB Hdd
  • Nvidia GTX 650 Ti Boost 2GB

Everything was running fine till a few days ago when Windows Explorer started crashing and hanging up the system.

When it happens some other programs sometimes also hang and crash too. Also I can't Ctrl+Alt+Del during its fits, it just comes up with a black screen. I can get the Task Manager with Ctrl+Shift+Esc but then that hangs sometimes.

If I manage to get explorer.exe to end, I often can't get a run window open for at least a minute to open explorer.exe. Even when it comes up it hangs and I end up hard reseting the computer. It seems to happen randomly and the CPU is <15 percent. I've done some research and it might be a HDD issue.

HDTune reports 11 bad sectors, I don't know how bad that is though. On another note, I've yet to run Malwarebytes. But Vipre Antivirus reports no viruses. I'm not quite sure whats up!

Also, if it could be related, I have been having a problem putting/waking from sleep. It says I get a BSOD (which I never actually see) that has error code 9f. Any suggestions, or ideas would be appreciated!

  • Follow the instructions from the following URL and upload your minidumps, so we'll try to analyze them and figure what's causing these issues: 0xpanic.com/#!guide1/cdpa – Matan Eldan Oct 10 '13 at 7:53
  • @HDTune - This is very likely caused by the bad sectors. I encountered this problem shortly before total kernel panics, which caused BSODs, that were unable to create a memory dump. My problem would be a problem for a few minutes then go away, then come back, then go away. But the inability to view task manager and the unresponsive applications are classic system disk failures. – Ramhound Oct 10 '13 at 11:01
  • Here's the minidump. dl.dropboxusercontent.com/u/22865035/100913-28189-01.dmp Malwarebytes detected nothing. I'm going to run Hiren's Boot CD and check again. – Jadar Oct 10 '13 at 13:17
  • Also, this is what HDTune is giving me. i.imgur.com/05x5nlU.png i.imgur.com/dkOkyz2.png – Jadar Oct 10 '13 at 13:22

Well... the minidump won't say much. As for the HDTune bench results: they aren't optimal for that drive, but nothing that will put that drive as the main culprit here.

I have 2 possible suggestions that might solve your problems:

1) Run MEMTEST86+ for a couple of hours for each of the memory sticks you have SEPARATELY. * If these issues occur frequently - you can just unplug one of the sticks and see if the problems still persists (if it is - try the same method with the other stick, on a different slot)

2) Try the system file checker: Open up the command prompt as an administrator then run: sfc /scannow

By the way - Please specify the exact model of your power supply (you can write a comment to this post)


Jadar just follow this URL and update the Broadcom drivers: http://wikidrivers.com/wiki/Broadcom_BCM43xx_win6x

  • the dump is very helpful. The very old broadcom driver is causing the crash, – magicandre1981 Oct 11 '13 at 17:01
  • Oops... my bad. you're right. I've no idea how I couldn't see "bcmwl664.sys" Anyway, I'll edit my post for a relevant solution. Thanks @magicandre1981 ! – Matan Eldan Oct 12 '13 at 4:13

This seems to be a ACPI issue in the BIOS. Check drivers on the video and use Windows Update. Review the event log for the time frame you mentioned and go from there.

  • What am I looking for? Windows is fully up-to-date. Just ran it a day or two ago. – Jadar Oct 10 '13 at 16:01
  • Ya, I don't see any errors in Windows Logs -> System that would relate to hard drive/ACPI problems. Just that the system was unexpectedly turned off. There is one error, though. Event 8003. I don't think that has anything to do with it, though. – Jadar Oct 10 '13 at 16:53

The dump shows that Broadcom driver (bcmwl664.sys) causing the crash:

*                                                                             *
*                        Bugcheck Analysis                                    *
*                                                                             *

So update the driver:


  • I'll try that! I do think it also has something to do with the nVidia update I did. – Jadar Oct 11 '13 at 22:09
