I went on vacation this last week and unplugged my computer to protect it from surges, save power, etc. When I returned home and tried to use it today, it will not power up correctly. All I did was shut off the switch on the PSU and unplug the power strip it's plugged into from the wall (I didn't open it up or move it at all), and it sat unplugged for six days. When I plugged it back in and turned on the PSU, the lights on the motherboard just flash fast and cut out constantly, not the steady cycle they usually do when the computer is plugged in but powered off. Nothing happens when the power or reset buttons are pressed. Everything else plugged into the same outlet/power strip works fine, I have moved the computer to a different outlet on a completely different circuit in the house, and tried powering it up with all the peripherals disconnected, but no change. I hope I don't have a PSU problem! Any help anyone can give is much appreciated! My build is in my signature, and here's a link to a video of what's happening: https://youtu.be/b0x_qfwwqo8

PS: Sorry if this is the wrong subforum, but seeing as I'm not sure what's happening, I'm not sure where to put it. Maybe not even an EVGA hardware problem, but I don't know where else to ask.

I don't have another.

Have you tried powering up using the power button on the board instead of the case?

How do your voltages look while jumpered?

How do I go about doing that? I have an EVGA Bot and 24 pin voltage jumper, but they're both in storage with most of my belongings in another state. I never learned to use them either. I think I can find a multimeter around the house. What pins do I need to read?

FYI, here's a link to a video showing what the lights should look like: https://www.youtube.com/watch?v=T1P1zkZmZpc. Compared to the video I posted.

  This may help...

So I should get the stated voltages when shooting between that pin and a ground, correct? And this is all DC, right?

1st question, correct.


2nd question, I'm not techincal enough to know all the ins & outs of how the AC to DC converting works.

All voltages on the 24-pin connector shoot good. Next, I'm thinking I should disconnect everything form the motherboard and try to power it up as you'd do the first time with a new build...

i had this happen once before, turned out to be the cmos battery, since your running a classy 3, x58 i assume, that battery might be quite old and can lose power when the psu is turned off, should be a 2016 or 2025  which are pretty cheap. 

Hopefully you'll have better luck than I did...(post #10)

That would be difficult to say without further diagnosis. I would recommend removing any non-essential components and going to a single stick of RAM and clearing the CMOS a few times or more. Keep in mind that if you have a RAID setup, you may not want to do this, as you can ruin the array and the data may be irretrievable.
 
I have personally had boards that give no power out of the box, but removing components and clearing CMOS allowed it to POST and after that happened, I was able to reinstall the other components and get it working fine. My go to is always to remove the graphics card and all but one RAM stick, then clearing CMOS.

Some boards will have a CLR button or a CMOS Reset button. Those should be held for about 5 seconds to clear the CMOS settings. If the board does not have this, you can remove the battery and unplug the power supply from the electrical outlet, then press the case power button, or onboard power button about 5 or 6 times, to clear any stored power and reset the CMOS.

Still no dice. It's like the board's not even powering up right.

If it comes to it; is it still possible to get an RMA replacement for an X58 board? I don't have the funds to change to another CPU socket right now.

This would be entirely dependent upon what is in stock at the time of replacement. That board is very old at this point and direct replacement may not be available, but there's always the possibility that we would get one in stock from a repair, etc. We would not be able to determine this until an RMA was in process, unfortunately. If it comes down to an issue with the board itself, feel free to contact our team at 888-881-3842 or Support@EVGA.com
