should I worry or not?

Hello! I am an owner of a m18xr2 alienware. While I was playing a game my system froze... no ctrl+alt+delete was working, nothing... So, forced a shut down (hold the alien head down for about 5 seconds), then I tried to reboot. When my pc booted, I hear the fans work, the led lights light up and... that's it! Couldn't go to bios and there was a black screen the whole time. I tried to reboot many times (with battery & without one), but the problem remained. I called dell support and after a few failed attempts the technician told me to shut down the pc, long press FN and boot it up (while pressing the FN button). Well it worked and got me to an error test scanner! After 40 minutes the test was complete, found no errors, then rebooted without any problems! To be sure I went to dell support website and run the diagnostics test (the quick one and the long one) and found that my machine was running properly without any issues... My question is should I worry? Will it happen again? Should I do something?

 

Monitor your temps to make sure your gpu's and cpu aren't overheating. Use like hwinfo and then start playing a few games or run 3dmark11 or heaven4 and see where your temps get to. Might be running a little hot and need a good cleaning and re-paste.

 

Well I am using MSI afterburner! I tested GTA V in very high settings and my CPU temp is 70 Celsius and the GPUs 55-65 Celsius...
