Hi, It might be a power supply issue. There's a test: http://www.youtube.com/watch?v=5FWXgQSokF4 . Connect a fan to the molex, short the pins and check if the fan does spin.
If it does, then connect back the power cables, leave only one RAM stick installed, disconnect all SATA HDDs but the DVD drive and test again.

Its 2 months old and has a 1 year warranty. Call them and let them diagnose it.
