I have a custom-built HTPC with the following specs:
* Motherboard: Intel DG45ID * CPU: Intel Core 2 Quad 8300 * Graphics: Integrated Intel Graphics Media Accelerator X4500HD (using HDMI) * RAM: 8 GB OCZ * OS: Windows 7 Home Premium 64-bit
It was working smoothly up until yesterday, when it froze during Hulu playback and I had to hard reboot. I have not been able to get it to boot back up, and it won't even load the BIOS screen or do the single beep when the computer turns on.
All of the fans are spinning, and I have tried removing all connections except for CPU, CPU fan, motherboard main power, and one stick of RAM.
I have tried switching out the RAM. I have also tried switching out the HDMI monitor for a DVI monitor.
UPDATE: When I switch on power supply, components (CPU, CPU fan, motherboard) power on for about 4 seconds before shutting down briefly and powering back on.
UPDATE2: Tried a cheap power supply from Frys and witnessed same behavior. Am in the RMA process with NewEgg at the moment for the motherboard. Will update again when I receive and test with the new one.
UPDATE3: Returned the faulty motherboard and the computer is now working again.
