Usually 3 restart it's a problem with USB 3.0 controller or this controller firmware. |

reset problem solved by replace usb3 controller(asm1042) but i have new problem now:(( i can just use maximum a 2GB memory module if i put 2gb modules on each slot,it work and boot up but when install 2x1GB,2x2GB or 4g module,it use about 1.7A after some moments usage increase to 2.3A for some secends ,then restart |
