Hi there...4 years ago with the help of this board I built my own PC as follows:

-Asus P67 Extreme4
-i7 2600k
-Hyper 212+
-Antec Earthwatts 380
-8gb ripjaws

The computer has run beautifully for 4 years. I had a 24/7 modest overclock to 42x multiplier and it was always very stable

So I get home tonight and it is dead. Son says he tried to start it earlier today and it was dead. It worked yesterday. Whaaaaaa.

I came back to Tom's and found the paperclip test for the PSU. When I shorted green to black, the PSU fired up and there was noise up by the front of the case...sounded like the drives starting up. There are no lights on the mobo and the LED number on the mobo doesnt do anything.

I then tore into my old Dell PC in the basement and tried mostly in vain to pull out the power supply. What a mess...those things were tighly placed. I was able to free it enough to get the 24 pin over to the Asus mobo. Still nothing. What I wasnt able to do was get any replacement to the CPU power cord as the Dell had about 2 inches of play.

QUESTION: DO YOU THINK THE MOBO DIED SOMEHOW OR COULD IT STILL BE THE POWER SUPPLY? At first I just assumed PSU, but when it started running on the paperclip test then I assumed the mobo died (how?)

While trying that other 24pin connector I also switched the jumper to clear CMOS as I saw someone suggest that.

WHAT IS MY NEXT BEST MOVE? I am not in an emergency but would like to get the PC up and running soon. Is it worth buying a power supply and trying that or did the paperclip test make it likely that my mobo bit the dust? If the latter, then what is path forward? Ebay another P67 Extreme4 mobo and try to do an even swap out? Embrace this as an opportunity to upgrade my system? Honestly the 2600k was plenty fast for what we use a PC for, and I am a frugal guy who hasnt really needed a extra 20pct on some benchmark test. PC gets used for web surfing and the occasional video editing/encoding project. Im happy to get a newer mobo I guess but then I worry about having to go through a reinstall of windows if the hardware is different.

HELP---thanks :)

I did....but most of these are for a brand new build that isn't posting,not a system that was working yesterday and not today.

I can poke around the PSU cables to see if they are giving out voltage although like I said it did pass a paperclip test.

There are NO phase LEDs lighting up when I try to start the PC and the little RESET and POWER buttons on the mobo also don't do anything.

My son did something to the front panel usb socket in the past few weeks while trying to plug in some gaming pad there. I noticed it a couple days ago but the PC was still working.

So the only thing I took from the Troubleshoot thread is to switch PSU or poke around with multimeter.
Is there a way to easily determine a dead PSU WHEN IT PASSES THE PAPERCLIP TEST (short of running to the store to buy one?)

I guess I need to go out and buy a new PSU to make sure that isn't the problem (and then if it isn't the problem should I return the new PSU and keep my 4 yr old Antec? - or is 4 yrs too old for a PSU and it will be dying soon too?)

Looking around if I want to keep my 2600K then it looks like a Z77 mobo would still work? I would love to be able to reboot from my current windows installation so I don't need to reload everything.....

So it turned out to be that the front USB ports that my son somehow mashed in were the culprit. Unplugged those cords from the mobo USB header and wouldn't you know, the PC sprang up from the dead! Everything seems to work fine now. Wow.

I thought the patient was dead and I was ready to bury it in the ground and it turns out it only had a debilitating hangnail......

So the first advice about running the troubleshooting was, indeed, spot on. Wish I had more time to do this last night so I wouldn't have spent most of a workday surfing these forums and researching new mobos etc. Oh well, I got educated.....

Thanks for the advice
