Hi -
Glad to hear that you were able to easily solve your BSOD.
Windows 7 & Vista systems by default set the crash dump settings to "Kernel Memory Dump" - which will produce a full kernel memory dump as well as a mini kernel dump.
Full Kernel Dump --> \windows\memory.dmp (overwritten by each BSOD)
Mini kernel Dumps --> \windows\minidump (new one created each BSOD)
Per kb254649 -
Kernel memory dump
A kernel memory dump records only the kernel memory... Depending on the RAM in your computer, you must have between 150MB and up to 2GB of pagefile space ... on the boot volume.
Small memory dump
... This option requires a paging file of at least 2 MB on the boot volume. . .
Full Kernel can be 250MB - 2GB or more; avg ~ 600MB
Mini Kernel = avg ~ 275kb Vista; Windows 7 ~ 325kb (I've seen some recently ~ 900kb)
The "allocated base size" (ABS) of the page file on the OS drive is another reason that no dump may be produced by a BSOD. The ABS = the size of the initial page file size allocation which usually occurs during OS installation. The ABS must be > installed physical RAM. If one were to upgrade RAM from 2 to 4 GB, the page file would increase in size for mapping physical and virtual memory addresses, but the initial allocation size would remain at the original size - just over 2GB if system managed. So, if upgrading RAM, it is important to delete the page file and allow the system to re-allocate it. It is very simple to do -
- turn the page file OFF; re-boot into SAFEMODE
- change file attributes for c:\pagefile.sys
- change file permission settings for c:\pagefile.sys (via takeown & icacls commands)
- delete c:\pagefile.sys - via "hard delete" - hold SHIFT key down when clicking "Delete" (it's too big for recycle bin) or use line command del
- re-boot
- turn page file ON - system managed
- re-boot
Check ABS and page file status/ location with the WMI script from my previous post.

I hope you continue to have a BSOD-free day !
