Copyed Bios2 to Bios1, switched to BIOS1 everything was working. After that did put back on MOBO USB 2.0, 3.0 ports. Then I did put PC back in place, pressed power button BAM, same thing. Then I removed USB 2.0 and 3.0 from MOBO, working. Added back USB 2.0 working, added USB 3.0 working ( While I was doing this I was holding PC on my leg ). Then turned it off, did put it back in place, bam. Again not working. Then I did remove USB 2.0 and it's working. I'm just guessing that it is USB pin problem, hard to tell... Sadly this happened after there was electricity loss</td></tr></table><br><br>Are you saying that when you removed the <i><b>USB 2.0 cable for the USB 2.0 ports on your PC case</b></i> from the mother board, the problem does not happen?<br><br>If that is right, the problem could be with the USB 2.0 connections or cable on the PC case. <br><br>You did say this problem did not start until after a power loss, so the board could be damaged, and the cable from the PC case is not the problem.<br><br>You could do a test if you had a USB 2.0 port adapter bracket that fits in a PCIe slot on a PC case. If you connected that to the USB 2.0 mother board header and if the board started fine, then the problem is probably the USB 2.0 connections in the PC case.<br><br>Your board has two USB 2.0 headers on the bottom of the board. Do both of them not work when connected to the PC case USB 2.0 cable?<br>]]>

I clear cmos, take out battery for more than 4 hour and nothing. It boots, the display is showing some codes and last one that I am seeing is d7. After that the mainboards reboots itself every 2 seconds.&nbsp;<div>Can someone directs me to Asrock RMA? (email address, phone number?).</div><div><br></div><div>Thanks.</div>]]>
