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.
Had the exact same thing happen to me. Two days after getting MW2 screen goes green/blue and switches off after a couple minutes. This is on a launch 360 that has been sent in for repair once. Said stuff it, bought a Jasper Elite, love how quiet it is. Plus I now have HDMI for added neatness...
Wow, I haven't had a single problem with mine since launch day, I keep it well ventilated and stands vertical or horizontal depending on my needs. Never hiccuped ever.
Good luck with your return though.
Just lucky I guess.
