Hello everyone. I am a new pc builder. I encountered some problems last night when I tried to assemble the PC. I bought following materials: Case: Fractal Design Arc Midi CPU: i5 3570K MB: Asus Maximus V gene Memeory: Kingston HyperX Beast 2x4GB 1600Mhz SSD: Crucial M4 120G HDD: WD Caviar Black 2To CPU cooler: CM Hyper 212 Evo PSU: Corsair GS600 GPU: none at the moment So everything was installed. I took a bit long time because of the CPU Fan, really hard to install for the first time. Everything else was quiet easy. When everything was set up, I booted the PC. I noticed 2 big problems: 1.It has last for 3 secs then turned off. A little moment after that, it turned on itself during 3 sec, then turned off again. And it just repeated this processus infinitely. 2.Another problem, two of the three connectors of chasis fan on MB just don't work. Because I tried to switch the three fans on chasis fan connector 1, and all three worked fine. But none of the three worked on connector 2 or 3. So I removed the HyperX ram and replaced them with 1 Corsair basic Ram. I removed SSD HDD CD Reader. I checked again, the problem persist. So I checked this problem on some forums. There is a lot of possibility according to the forum members. 1. MotherBoard is partially dammaged during installation. I may dammage some pin behind or in front of the MB.(Probably True) or I put too much thermal heat sink on the CPU. 2. The PSU is not enough to provide power for the entire PC.(I don't really think so) 3. Screws and standoffs are not correctly fixed on the motherboard or some standoff are totally missing. True, I followed the Bit Tech August build Guide 2012 article and chose Fractal Design Arc Midi Tower and Asus Maximus V gene MB, and on the MB, we have 8 socket for standoffs, but on the tower, we only have 7 sockets for clues. I have already asked for a RMA for this MB, because anyway, i think i was not gentle and careful to install the MB and maybe I really dammaged some components on the MB. I received a new one today, this one really doesn't seem to be a brand new one. The CPU protection armor is just out of position when I unboxed. Also there is some scratch on the Sound Card. I really don't feel that this one is new. I just don't feel to install some refurbished MB in my tower even it will work. I am totally lost, I don't know what to do, and I don't know what was exactly the problems. Please help me. I am sorry for my bad english but it is really something urgent. I need to finish assembling this PC to offer it to my brother as a Chrismas Gift. Thank you in advance. Any suggestions would be helpful.
