I am having some power issues with my PC that sometimes posts other times not. Sometimes I get the "Overclocking Failed! Please enter Setup to re-configure your system" message. Other times no messageat all and the systems posts.

The systems is not overclocked. Usually my config is 12GB RAM 1600MHz that I downclock to 1333MHz. There was no problem, but suddendly these power failures issues started to happen.

So I have loaded the default sets in the BIOs, and I changed it from 12GB to 6GB RAM in XMP, but still having the same problems.

I have had these issues before, and it was the power supply I have RMAed.

Is my power supply dieing again?

Without knowing what motherboard, ram, cpu, psu etc makes and models, nobody can help you.

What psu did you buy before that failed?? What is this one now?

Check the voltage that your ram needs and make sure it is set properly in the bios.
I beleive that line of ram needs 1.65v and the bios may be defaulting to 1.5v

The hardware config is on my info. As it was RMAed, the PSU is the same (PS Corsair 850W).

All Voltages are set properly in the BIOS. Even in XMP the issue appears. Now I loaded the default sets for a test, so RAM is set to 1066MHz.

Just a quick update -- after having loaded the default sets it didn´t post. Then I changed the memory kit (all 3 sticks). It didn´t post. Then I cleared CMOS. No post!

I kept myself trying, then it posted, however I am 100% sure the problems is still there somewhere.

I will keep you informmed. Thank you all for the replies.

Hi all,

I have just made the PSU test as shown here (http://www.youtube.com/watch?v=5FWXgQSokF4)

By the test the PSU is working properly.

So, if it isn´t the PSU, then what should it be?

Sounds like it may be pointing to a mobo issue.
I can't say for sure what that might be though.
When i've run into issues i've resorted to a clean O/S install.

The point is that the PC doesn´t start anymore, so there isn´t a chance for a clean O/S install.

How do I test the mobo?

If i recall did you not ask about a ups months ago because of power issues?
If so did you get one?
And is you system plugged into one or the wall?

Exactly! It appears like the same issue, but that time it was the PSU that I RMAed. Now I tested the PSU that seems to be OK.

I had taken the UPS long ago, it was running OK, but when the power issues started, I plugged the system in the wall. I have just tried to start the system with the UPS without sucess. :(

Well obviously that ups has problems.
Maybe dead batteries idk.
So with the psu plugged directly in the wall are you still having issues?

The UPS is working properly; even plugged directly into the wall the system doesn´t post.
