Today I assembled the following desktop:
GIGABYTE GA-Z77MX-D3H Motherboard
Core i7 2600k
CoolerMaster Hyper 212+
2x4GB DDR3 1066 RAM
OCZ ModXStream 600W Pro
Testing with only these components (case fans and Hard Drive disconnected to rule out problems), the following happens:
I plug in the PSU and turn it on; the CPU fan turns on, if the hard drive is connected it seeks a few times and the whole thing shuts off, nothing on the screen, no beeps or other noises. I have tried using both stick of RAM in the DDR3_1 slot of the board to rule out a RAM issue. The PSU works fine when connected to a different motherboard/CPU. I've disconnected and reconnected all cables to make sure they are secure. I'm really at a loss of what else to try, do you have any suggestions?
I applied about a rice-sized portion of thermal grease to the cooler itself (that's what the instructions showed) and spread it out with a credit card. I've also tried resetting the CMOS by removing the battery for ~10 minutes.
I'd really appreciate it if you could help me figure out what's wrong! All components are brand new except the PSU.
