Dell XPS Freezing Frequently, No BSOD's
Hello everyone,
I'm having a problem with my PC freezing and sometimes crashing and rebooting itself. For example, I left the PC running the other night and noticed it had restarted at some point. I checked the Windows log and noticed the errors "The previous system shutdown at 6:39:12 AM on 12/3/2013 was unexpected." logged at 12/3/2013 6:57:54 AM and
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." logged at 12/3/2013 6:57:35 AM.
The only errors I see prior to that are "The driver detected a controller error on \Device\Harddisk6\DR6." logged at 12/2/2013 1:49:41 PM
and
"The Intel(R) Management & Security Application User Notification Service service depends on the Intel(R) Management and Security Application Local Management Service service which failed to start because of the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it." logged at 12/2/2013 11:44:37 AM.
and a warning
"The driver \Driver\WUDFRd failed to load for the device WpdBusEnumRoot\UMB\2&37c186b&0&STORAGE#VOLUME#_??_USBSTOR#DISK&VEN_GENERIC-&PROD_COMPACT_FLASH&REV_1.01#18E391066476&1#." logged 12/2/2013 11:42:35 AM.
FWIW, the last event listed prior to the 6:39 AM unexpected shutdown was "The WinHTTP Web Proxy Auto-Discovery Service service entered the stopped state." which was logged at 12/3/2013 6:36:39 AM".
Can these types of errors and warnings cause the system crashes I'm experiencing? I'm doubting it only because they occur hours before the system actually crashes. The disc referred to in the error with the ID of DR6 is an external USB drive that I hardly ever use. I accessed msconfig and restarted Intel(R) Management & Security Application User Notification Service , rebooted but the PC has still since locked up. I googled the error that refers to the driver but didn't come up with much useful information I believe the driver error is referring to my ATI Radeon 5450 display adapter but the drivers for it are up-to-date. Also, it seems the PC freezes more often when I run Dragon Naturally Speaking dictation software.
I've also ran CHKDSK as well as memtest86+ and both came out fine. If there's any info y'all can provide on fixing this problem it would be greatly appreciated!
Memory dumps & sys info attached.
