Need some help finding possible solutions before I start RMAing good parts.
Problem: System and motherboard have power, but no boot or POST.

Symptoms: Started out OK. System worked for about 2-3 hours, and then went bad. Installed OS. Updated BIOS to ver. 0302. Installed and updated Marvell drivers, ASUS drivers (except AI utility), EVGA GTX 260 drivers, SB X-Fi drivers. Had 2 or 3 times during that period when monitor went black for a couple of seconds, then came back on. During one restart while installing drivers, system hung before boot: did not go to Express Gate SSD, fans running full speed, all 6 white LEDs and one blue LED on MB lighted, monitor has no signal, HD not spinning up. Reset button on MB and case do not work. Have to hold on/off button for 5 seconds to turn off.

Actions: Turned on/off multiple times – same result, no boot. Removed sound card, disconnected DVD optical drives, replaced HD with a new clean HD – same result. Reset CMOS several times by changing jumper from 1-2 to 2-3 and back, both with and without battery installed – same result. Removed video card: case fans ran a little slower when started without it, but still no spin up of HD (reinstalled HD with OS). Reinstalled video card, fans back up to full RPM, still no boot. Did not overclock. I have successfully built many low and higher-end systems over the years, but this is my first LGA 1366 build, and my first with an ASUS mobo. Unfortunately, I don’t have a lot of compatible spare parts lying around to replace each one to test.

In this situation, it seems there would be some hardware problem, maybe you need to contact your retailer for a check
