startup problems

[aezakmi]

Hi

 

Whenever I shutdown and then cut AC power to my pc (usually during the night) and then try to start it the next day it turns on for a second, then off and then on again and does POST normally, not a big deal but I wonder why it does that every time, it's been doing it since the 1st day. restarts and sleeps ok

 

devices are protected by a breaker and the PSU+monitor by an UPS, thought it was the UPS so I plugged the PSU directly to the wall just to get the same result. outages and random spikes are a daily thing especially during cold days (some guy in town decides to plug his brand new 8000W heater and my voltage drops from 230 to 180 when I'm in the middle of a ranked game and breaker trips, UPS goes online, game minimizes and I get kiled and give the enemy extra gold, my team wants to report me..)

 

I had the same PSU with a different build and everything worked fine

RMA of components is not possible

it means it is boot failing at startup. u prolly got some bios settings wrong and it reverts to default after boot failing

 

sleep mode also has to be supported / set good in the motherboard ( power saving states ect )

That or maybe the BIOS battery is bad.

Probably trying to boot and the memory timings aren't stable then adjusts them and tries again. It happened to me my rig awhile back too.

I'm using the stock timings AFAIK

It wouldn't save time/date

Stock timings can still be unstable of you have a poor memory controller.
