I have dell xps 8700. I've had it for 2 1/2 years now. It stopped working in late october. My brother was playing DayZ. The game froze and he pressed crtl-alt-Delete a couple times. He turned the computer off and ever since then when I start it it starts a cycle with the fans spinning and stopping repeating. I got dell to run a hardware test and they said it was software. After that it worked for a bit and gave me a windows kernel error. I'm on windows 10. And it's back to the cycle again. What should I do?
