Hello Match,
It depends, when I'm playing games it just freezes other times it reboots.
Unfortunately the ctrl,alt, del doesnt work, I have to use the hard reset button.
It's always around the same temperature. I've checked using the BIOS and using the software provided with the motherboard from ASUS.
The PC is just running normally and then suddenly, screen freezes, keyboard lights go off and if I have my speakers on I get this sort of play back sound over and over again. However the fans carry on running and all the internal lights still work, just like normal.
When I boot up I get that window saying if I want to run in safety mode or normal mode (plus the other silly options).
