I ran into a problem this morning. I attempted to turn on my rig and nothing. No fans, sounds or nothing. The green power indicator on the mobo is working though. I dont have an extra PSU to test it with but im either thinking its a defective PSU or maybe a fried CPU (although I dont overclock). I had the issue this morning, walked away, and it fixed itself. But then I got the problem again today.

Any feedback is appreciated.
 
It does sound like a bad PSU. But one quick test you could do is reset the CMOS. I changed a bios setting once and then i coudn't boot. Cleared the CMOS as was back up and running. If that doesn't work, I would focus on a hardware issue.

indeed, sometimes that happens to me, a good old CMOS reset and problem fixed. :)

also make sure your heatsink is installed properly
 
Ok, I tried resetting the CMOS and the system is still unresponsive. I also tried a different power button I had lying around and that didn't help. The heatsink is properly seated but I took it off and resat it for good measure. Does anyone have any other suggestions other than RMAing the PSU?
 
okey now, next step is to unplug everything non essential and try to boot.
remove the RAM, Vid Card, unplug optical drives and HDs, leave only the PC Speaker, CPU and heatsink fan plugged in. Then try to start the PC, it should beep, if it doesn't then it is either a PSU problem or a Mobo problem, and also but less likely the CPU.

To be 100% sure, you´ll have to test another CPU in your rig and repeat, it'll be better to check your CPU in another working PC
 
Your signature shows you running a 680i mobo. While i don't have any experience with that particular chipset, I have read quiet a few post about them being a bit on the unreliable side. If you happen to know someone who has a computer using the same socket but different chipset, you should try to rule out your cpu. You have a high quality power supply, so I'm hesitant so single it out.
 
auctually that mobo info is outdated, i have a ASUS P5N-E atm.
I took everything that isn't essential out and tried it with no success. I also managed to find a working PSU and tried that and still nothing. I've narrowed it down to either CPU or Mobo. What do you guys think?
 
i'd say it's the mobo, there are a lot of components in there and if only one malfunctions the mobo won't work
 
I have to agree with the poster above. It's really uncommon for a non-overclocked cpu to die suddenly. Motherboards on the other hand have so many different, delicate parts that I'm surprised that more don't fail after a time.
 
I managed to borrow a PSU from someone and turns out thats the problem. Hello RMA, lol.
 
glad you found it to be an easy solution. I was going to tell you to short the pins that go to the power button with a screwdriver to see if the button was junk on your case.... may sound farfetched but hey i found a condom wrapper underneath a secreterys computer in a dentist office once.
 
I had either a PSU or mobo go out on me. Luckily I had an old PSU and just tested the mobo. I couldnt just switch out the PSU because the wattage on the older one was too low for my system. My PSU was dead.
 
Your PC Power & Cooling S75QB 750W died?!? How old was it? Do you have a UPS? Just curious.
