Hi all,
I have a custom built PC that is brand-new (build completed about a month ago) and is running the following components:
Power Supply: EVGA SuperNOVA 650W GS 80+ Gold
Motherboard: Gigabyte GA-Z170X Gaming 3
Case: Fractal Design Define R5
HDs: Sumsung Evo 850 SSDs (2 of them)
GPU: EVGA GTX 1080 FTW
RAM: GSkill Ripjaws V Series
OS: Windows 10
Ever since I completed the build I would sometimes have an issue with the PC not turning on when I hit the power switch. The only way I've been able to correct the problem is by manually switching the PSU off, waiting until I hear the power dump out of the mobo, then switch it back on and wait a few moments before trying to power it up. I've ensured all connections are correct and are solid, as are all power connections, plugs, etc.
After reading about similar issues in the forums, I'm going to diagnose the problem with the paperclip test on the PSU and the screwdriver test on the mobo, and the case switch test by swapping the power button and the reset button connections.
My question to all of you, is what sounds like more a plausible issue given the following:
1) If the system is unplugged/PSU switched off long enough for the stored power to be "dumped" and plugged back in/switched back on, the system will not immediately start. It takes several seconds before the motherboard is fully powered again, and then it'll start. I've never had a system that's done that before and I don't know if it's something new to mobo designs or if it's an issue with the way the PSU supplies the power?
2) When I turned my system on yesterday, I heard a very loud electronic whine that eventually went away after about 30 seconds and has not returned. I do not have any mechanical hard drives, and it should not have been coil whine from the video card since it wasn't under load. Is this an indication of PSU failure?
3) There are times when resetting the PSU doesn't help. Again last night I turned off my system, then tried to turn it back on and it would not start up again even after switching off the PSU, unplugging the system, letting it sit for several minutes in both powered and unpowered states, etc. Even though it wouldn't start, hitting the power switch still had a notable effect of -trying- to start. (Lights in the room would momentarily dim like a major appliance turning on but nothing else would happen).
I did eventually get my system to restart this morning after leaving the PSU switched off all night, and I haven't turned it off again in case it won't restart. All other functions of the system seem to be working fine - no mysterious losses of power, sudden restarts, turning off on it's own, nothing of that sort.
I'm leaning toward it being a switch issue, but given the other items above, I'm just not sure.
Sorry for the wall of text folks. Thank you to anyone who takes the time to read this and get back to me.
