Double boot On Gigabyte 990fx when changing bios settings

Hey guys,

Just joined and and posted my first question and got such a quick a great response. Thought I'd ask you guys another question that's been bugging me.

I have a Gigabyte GA-990FXA-UD3 AM3 990FX DDR3 Motherboard running a FX8350 with a GIGABYTE GTX 780 OC edition which is currently being supplied by Thermaltake LitePower W0355R 600Watt PSU.

Anyway, when I touch any of the bios settings and I turn the computer on for a cold boot, the power comes on then straight off..then on an runs normal. It doesn't do it when it's set to default. I read that it may be the motherboard syncing with new settings but if that's the case why does it need to sync every time it's switched on? Any thoughts or comments would be appreciated. Thanks!

  4. Thanks mate! You seem to be the power supply captain. Do you believe that the psu can cause the cpu to throttle back to 3400 mhz during prime 95 or is that a separate issue?
  5. If you have an unstable power supply , Yes.
