Building an new PC, this is my first i7.x58 build but have built many before.
GA-X58A-UD3R Rev 2.0
Intel Core i7 930
Corsair TX750W PSU
6 gb Corsair Dominator DDR3 RAM (3x2gb sticks)
ATI Radeon HD4870
Windows 7
Built system with all components above and on power up system power up for 10 seconds with phase leds on motherboard lit. System then powers off, no critical beeps from case speaker. Will not restart on push of on/off switch must power cycle at PSU or power point to get system to 'boot'.
Clear CMOS - same symptoms on boot.
Break down system, removing drives, GPU and 2 RAM sticks - same symptoms on boot.
Move RAM around, replace with other sticks - same symptoms on boot.
Remove all RAM - same symptoms on boot.
Take components back to shop and they replace PSU, motherboard and CPU. Rebuild - same symptoms on boot.
At this point I was really starting to doubt myself, so I rebuilt system on an anti-static workstation and used another case speaker - same symptoms.
Back to the shop, replacement motherboard and PSU - same problems.
I am baffled. Can I be so unlucky to get multiple failed components? I am supposing minimum build needed to post and get critical beep messages is motherboard, CPU and PSU, correct?
