Hey Kaido - I am a complete beginner at this, and built my first hackintosh based on your specs.
I have what I think is a hardware troubleshooting question, but since it was running as a hackintosh and died in a particular way I thought you might have some ideas.
I'm not sure where I should post this, so if this is the wrong place, please tell me.
Specs:
MOTHERBOARD: GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard
PROCESSOR: Intel Pentium E5200 Wolfdale
PSU: Antec earthwatts EA380 380W
RAM: G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit
VIDEO: ZOTAC ZT-73TE250-HSL GeForce 7300GT 256MB
STORAGE: SAMSUNG Spinpoint F1 HD103UJ 1TB 7200 RPM SATA 3.0Gb/s Hard Drive
PCI Ethernet: ENCORE ENLGA-1320 10/ 100/ 1000Mbps PCI Ethernet Card
OPTICAL: LITE-ON 20X DVD±R DVD Burner SATA
AUDIO: SYBA SD-CM-UAUD USB Stereo Audio Adapter
CASE: SILVERSTONE Silver Aluminum LC13-S ATX Media Center / HTPC Case
As you can see, I mostly used your recipe for an HTPC rig. I wanted a machine that could run iTunes (with a massive library), play DVDs and video files once in a while, and download torrents.
I assembled everything and got it up and running using your detailed instructions, methods and the UD3P package at InsanelyMac. Running completely at defaults, no overclocking. Everything seemed to be working fine for a few hours - I set up the account, browsed the web, installed a few apps. Then I started copying audio files over, and after a while it just shut down... At the time, it was about halfway through copying a 150 GB directory from an external firewire drive, and I had just accessed it with Screen Sharing from another computer. After it shut down, I unplugged it, replugged, tried to turn on - the power LED flashes once, and no boot. I tried resetting the CMOS, swapping the RAM, disconnecting all devices, but it just flashes the motherboard LEDS, the processor cooling fan twitches, and nothing. I tested the PSU with a jumper, it came on and spun the case fan, and I verified that it's putting out the correct power by checking the 3.3, 5, and 12 v with a multimeter. The motherboard looks fine - no visible shorts or smells. I pulled the CPU and nothing there looks burnt, pins look fine, etc. Since I don't have much experience building PCs at all, the only things I can think of are:
1. RAM - I used G.Skill, which isn't in the list of acceptable RAM. If this is the issue, it seems like it would probably boot with the RAM in a different configuration (1 stick in 1st slot, or 2nd slot...), though - unless it was just bad or both sticks just died. Probable?
2. Motherboard - some of the negative reviews for the UD3P on Newegg sound like the board dies in similar ways. Any other experiences with this?
3. PSU - it's possible that I overloaded it, I guess... some of my components are a little more power hungry than Kaido's example rig. It tests okay when jumpered and unplugged from the motherboard, but might not be able to deliver the right power when it is plugged in. Any ideas on testing this?
4. CPU - if this died, I have absolutely no idea how I could tell.
All of this stuff is brand new, never tested before. I also don't have any other proven components to swap in, but would be open to buying other ones to test as long as I can still RMA things later...
Any help is appreciated, and thanks for reading through this - if it belongs somewhere else, just let me know.
