	Im in the same situation. At first the system would only sometimes boot, only bios. i send it back to the shop, and they send it back commenting that there is no problem. (they updated the bios) i received it back, and could succesfully install the os, and used it for 2 weeks. yesterday i rebooted the system and it would not boot anymore, sometimes only bios. i used 3 types of memory, both 2 sticks or 1. i used 3 types of psu, 2 normal and 1 picopsu. using a ssd as storage. i will try the suggest fix of parsec, connecting a 12v fan to a molex connector. anyone has a different solution?

	I have bought this MB half december 2016. The case is a MS-Tech CI100. Installed W10. I have build in a 80mm casefan, because the case is very small. In the beginning of March I got the first problem. After turning on, W10 won't start because the date and time were back to the default of jan 2009. So I have to modify date and time in the bios. The Cmos battery was 3V! I had this a couple of times. 2 weeks ago, suddenly I could not use my keyboard and mouse during my session, both PS2 connect. And after the reboot, nothing at all. The power led burns 1 sec and that's all. MB out of the case, tested with another PSU, the same problem. Last week I have sent the MB the my supplier and he has sent it to Asrock Europe. Now still waiting what is happening, a repair, I can't imagine that. Meanwhile I am very curious if my problem is also the problem of/by others. And may be, this is so, I will follow this post !! Still a question about the CPU State support. I read : Set this not lower than C7 as an initial test, and if that fails, use C6. But for me, C6 is lower than C7, mathematical. And yes, the manual shows C10 as default.

	Good Morning Everyone. I have a question about this post, i've encountered exactly the same issue with my new board. I only wanted to know if replacing the board was the correct solution. After i've read the last answer here i've tried with a haswell certificated PSU, but no luck at all. Thank You.

	The processor used in this board, the Intel J3455, is an ultra-low power device, that supports up to the C10 C State power saving setting, that is otherwise only found in mobile/laptop PC processors, that use battery power. Like the earlier Haswell generation desktop processors that supported the C7 C State, the J3455 is even more of a difficult load for a PSU. That is, the load on the 12V rail for the processor VRM stage could go so low, the PSU could see a virtual zero load on the +12V rail, become unstable, go out of ATX voltage spec on the +12V rail (normally over spec), and either shut off or function abnormally. User reviews of this board mention additional loads on the PSU help with its stability. Any PSU that is not at least rated for Intel Haswell/C7 use will likely not work well with that processor, unless certain precautions are taken. Meaning any PSU over three years old in its design will need these precautions. That is, a load must be put on the PSU's +12V rail from another source. Connecting a fan to the CPU Fan header is a good start. If SSDs or 2.5" HDDs are used with this board, they only use +5V power, so don't load the +12V rail at all. Only 3.5" SATA HDDs use the +12V rail, and the Intel 730 model SSDs. Connecting a case fan directly to the PSU via a molex connector will load the +12V rail enough. Otherwise, in the BIOS, CPU Configuration screen, set the Power Gear option to Normal or Sport. Set the CPU C States support to no lower than C7 as an initial test, and if that fails use C6. The C10 C State seems to be the default setting. The passive CPU heat sink will need some air circulation, where the case fans will come in handy. I also suggest updating to the latest BIOS version.

	Same story with my new Asrock j3455-itx. Tried 3 different compatible RAM modules in every combination. Also another power supply. Only one time in this period I had a picture and got into BIOS. (Display showing several starting error. Never happened again. No picture via VGA nor HDMI. No nothing. Only the CPU fan runs when I connect the power chord. I also can't power of the machine. When I long press the power button, fan goes slowly and starts spinning again. Today I returned the board to my dealer for exchange. Hope the new one will work. 1 week of stress getting components for testing, to finaly realise that the board has to be corrupt.

	I have bougth the board 2 weeks ago and in the first few days i have installed win 10 as OS. Everything was fine in the first week. About a few days later after a regular shutdown the problem started. I could get the system running one or two times by removing the BIOS batter over night as written in the guide, but since 2 days ago it does not work anymore.

	Has it worked previously or is it new? I would return it if possible. DOA boards happen on occasion and if it isn't the board then the next one will exhibit the same symptoms, at least you will have the peace of mind that you returned/replaced it.

	Like I have written in the first post: - The PSU fan spins up, yes - NIC does NOT lighten up, no - According to ASRock the crucial memory is compatible: CT102464BF186D.M16FP (http://asrock.com/mb/Intel/J3455-ITX/index.de.asp?cat=Memory), first one on the list. Also the alternative memory i tried does not solve the problem: Kingston KVR16LS11/8 which is also in the compatible list of ASRock If no one ever encountered the same issues or has any clue, I guess the only option for me is to return the board. But thank you for your attention.
