Hello Forum I just bought an Asrock J3455-ITX mb and can install win 10 from an UEFI USB stick just fine, but a couple of minutes after installation standing on the desktop doing nothing, screen starts turning of and on and red pixels appear all over the screen. Further more, when trying to installing any driver they install fine, but after reboot the boot crashes when the windows logo appear. 2x4 GB DDR3L HyperX 1866 MHz liteon 256gb SSD 60W micro psu Any clue as to whats happening?  |

Forgot to mention that the whole system draws a max of 20W according to my powermeter in the wall socket. |

Is that right, a 60W (sixty) PSU? If so, that is woefully inadequate even for a small board and PC like this one. Otherwise, I would check all the connections of the PSU to the board and the SSD. Using a new SATA data cable would also be a good idea. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Yes it's 60 (sixty) watts  it came with the itx case and listed similar boards as compatible, so i thought all was good. What size do i need? I'll go over the connections again. |

" rel="nofollow - A 60W PS should be more than enough. Been using a 12V 3A PS for months. I recommend switching to 1 RAM for a while or another maker. How do you connect your screen and what resolution? ------------- http://cellarcinema.info |
