I am not sure if it's the power supply or something not plugged in right (there are two extra cables that aren't plugged in, one that according to the instructions I shouldn't have to plug in and the other is a male connector to something in which the directions give no heed about whatsoever). Also remove all RAM modules except for 1. I'd go for the minimalistic route. My thought is the power supply is screwing up, but they don't have an extra one to test it with. Run the PC barebones (disconnect all peripherals except the monitor). The model is https://en.wikipedia.org/wiki/Dell_XPS#XPS_630 if that helps any.

Wife was using the computer when it suddenly froze. I had plugged everything in several times, trying different orientations and what not, making sure everything is in right, but nothing will turn on except the mobo LED light on the board. No other lights either. Detach any DVD / CD drive and HDD. Poor Dell onsite tech, horrible job!

Maybe simply a bad supply. No sound, just the fans spinning up, then the light starts blinking and the fans spin back down.
