Windows 7: BSOD Win7 x64 New PC - Can't create a minidump file?

BSOD Win7 x64 New PC - Can't create a minidump file?

I recent built a new PC and after 2-3 days i got my first BSOD. The frist thing i did at this point was go to Startup and Recovery and make sure it was set write a small memory dump, Automatically Restart is also checked but for whatever reason it just sits on the BSOD until i force a power off and no files are written to disk. I also tried to do a kernel memory dump but that also doesn't create a file. Is there any reason i would be unable to create this?

I only get the BSOD every 24-48 hours if i leave it running overnight

Memory dumps aren't always written to disk - there are many different reasons why they aren't captured. Generally it's too much work to try and fix them - but we'll see after having a look at your system. Does the BSOD occur on boot up or shutdown? If so, try to describe exactly when it happens (it'll give us some clues)

First, please provide this info from the BSOD: How To Find Bsod Error Messages

Next, please provide this info so we can see what's happening:

usamsa's reference is excellent.

Let us know what the event viewer showed.

Be sure that you've enabled the writing to the event log.

Here's a write-up which may touch on a couple of things which would prevent you from having a memory dump.

Small memory dump
· A paging file on the “boot” volume.
The "boot" volume is the one containing \windows.

Paging File Size is set in the ADVANCED SYSTEM PROPERTIES

ADVANCED SYSTEM PROPERTIES (left-hand pane) | Advanced tab |
Virtual Memory section | Change button |
checkmark Automatically monitor pagefile size for all drives |

· Minidumps must be selected
Minidumps are selected in the ADVANCED SYSTEM PROPERTIES

ADVANCED SYSTEM PROPERTIES (left-hand pane) | Advanced tab |
Startup and Recovery section | Settings button |
System Failure section |
checkmark Write an event to the system log |
checkmark Automatically restart |
select Small memory dump (box under Write debugging information) |
Do NOT checkmark Overwrite any existing file
If Overwrite any existing file is greyed out, then
Select Kernel dump, uncheck, and reselect Small memory dump |

· WIN | Services.msc | Enter
· Under Name, locate Windows Error Reporting Service
· If Status is not Started, then
Right-click on Windows Error Reporting Service |choose START
· If Startup Type is not Automatic, then
Right-click on Windows Error Reporting Service |
choose Properties | General tab |
set Startup type to Automatic
· Close Services.msc (I like to use ALT + F4)

After a crash, the minidump file will be in C:\Windows\Minidump

Be aware, that as usasma said, not all bsod's result in a dump being written out due to timing problems. Sometimes the condition occurs very early in the boot process before the system has had time to prepare for a bsod.
