Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
Nowadays it's user-choice...not really this versus that.
My Graphic Design Tech courses had Macs that we had to use and they sucked (performance) compared to my home PC for doing projects in PS and Illustrator.
We tried something similar to the portable vac/blower and it sucked compared to the power of compressed air, plus you have to charge it or plug it in to use it.
As soon as the notebook shuts down can it be powered on again? If not...it's definitely overheated.
...and to clarify...it is shutting down right? Not restarting?
Why would an online retailer have 300 demo boxes sitting around in their warehouse to begin with? Even if they were demo boxes, they were poorly-made and not labeled as demos... Which is definitely not up to Intel's standards. I love to bash Intel...but they know their products and control...
