If your System event log contains:
Event ID 43 Description: Crash dump is disabled! NT failed to initialize the boot partition paging file for crash dump. This may be because the system has more than 3.8 gigabytes of physical memory.after applying SP4, you pagefile is/was smaller than physical RAM.
Use Control Panel / System / Performance / Change to set the Initial Size and Maximum Size (on the %SystemRoot% partition) to at least RAM + 12.
NOTE: Initial Size and Maximum Size should always be the same to prevent fragmentation of the pagefile space.
Configure Dr. Watson using Control Panel / System / Startup/Shutdown.
Minimum recommended Pagefile size:
|16 - 96||RAM * 2|
|128 - 256||RAM * 1.5|
|>256||RAM + 12|
If you have a SCSI controller and additional physical drive(s), you can create the additional pagefile
space on the least used drive(s). Never place more than 1 pagefile on a physical drive.
