so, its 11 pm, I'm gaming as normal, when for no apparent reason, there's a crackling from my case and my system powers off. Now, the mb lights come on and the post display, but it refuses to start up. System is only a year old. I called scan but they want to know which component specifically is dodgy. Seeing that I can't actually power on the system nor have the spares handy to run individual tests, I'm a bit screwed. Any suggestions to what I can do? Specs are in my Sig .
