Windows 7: Strange random and sudden power cuts on laptop

Strange random and sudden power cuts on laptop

HP Envy 15 3xxx

I seem to be having crashes on my laptop as of recent, but the patterns they follow are very strange. It's almost like i'm getting a BSOD while it being used, but instead the screen just go black and all power cuts. It then reboots and starts up as usual. As far as I can tell there is no conflicting software causing this, and it happens without any pattern. Since there is no Blue Screen, I cannot give a dump file. However, on the even
viewer, I see an event labeled

"Critical 8/22/2012 8:29:48 PM Kernel-Power 41 (63)"

under the critical category. Now this seems like the CPU or other internal component is overheating, But when i look at HWMonitor Pro, the CPU stays under a steady 84C under load and 60C idle. This happens in a range of occasions such as rendering videos with Handbrake to simply browsing the web. I will say this, I recently swapped out my RAM cards because the OEM one's were causing BSOD's about a month ago.

If you'd like more specific information on the laptop, visit my old thread. All the info is up to date, but i will re-do any tasks if you ask me to. Thanks in advance!

I have almost this exact problem, but on desktop PC. I get the kernel power log, although in my case I think this is caused by the hard re-set I have to do to get the computer working again.

EDIT: I should also mention that the power will cut regardless of if it is connected to AC or if it is on battery.
