Solved Unexpected blackouts while watching videos

[set9676]

This has happened on and off for a while now, usually when I'm watching videos, using Skype, etc. My laptop simply shuts down without warning and then on re-booting asks me to use startup repair, which usually fixes the problem. Doesn't always include a BSOD, but last night it did when I re-booted. What do people make of this? I've also noticed my laptop gets extremely hot when this happens.

Thanks.

----- ETW minidump data unavailable-----
Probably caused by : ntkrnlmp.exe ( nt!ExpSystemErrorHandler2+5e1 )

Usual causes:  User-mode device driver, system service, or third-party application, Mismatched system files

This bugcheck indicates that the winlogon.exe process has been terminated unexpectedly, this process is used to log on and log off the user. I believe you most likely have overheating issues, please post a screenshot of your temperature with HWMonitor CPUID - System & hardware benchmark, monitoring, reporting, and then upload the screenshot with http://www.sevenforums.com/tutorials/9733-screenshots-files-upload-post-seven-forums.html

Remove:

Start Menu\Programs\Norton

Norton is known to cause BSODs with Windows, please remove the program completely using the Norton Removal Tool, I see that your also running MSE, running two real-time protection programs at the same time, can cause severe conflicts and crashes.

So this after about an hour of watching Hulu. Those core temps look hot. Any thing I can do besides trying to blow dust off the fans?

Those temperatures are really hot, buy a can of compressed air and then gently spray onto the fans. If your able to find a guide or know how to remove the back panel of your laptop, then you will be able to much more effectively remove any dust.

Where do you place your laptop?

Well I took it apart as best I could without going beyond my comfort level. Seems to have improved slightly. At least now I know what the problem is. Thanks for your help.
