Hey there!
So i have this problem with my desktop pc losing power most of the times when I come in contact with my motherboard's I/O connectors on the rear of my computer. When I say "most of the times" I mean 9 out of 10 times it will cause power loss, but that one random time it will work fine.
It usually happens when I plug in/unplug a USB device of any type, although it's not limited to USB devices only - happened also when I unplugged my ethernet cable, plugged in speakers, etc. It can even occur when I just touch something back there for example just touching USB port with just the very surface of my thumb drive before i actually push it into the port. Even when I pull my keyboard or mouse on the desk a bit closer to myself (carefully of course
) the resulting minimal movement of the wires is enough to cause reset.
The power loss can be instantaneous (computer restarts momentarily) or it can be longer (computer stays off). The latter case is actually a bit more complicated - often times when I plug in a device that causes an outage (for example, a USB mouse), the power seems to be lost for good, the power LEDs on my graphics card are out (I don't have any on my motherboard). Thing is, recently I noticed that if that is the case the computer actually tries to re-supply the power after a time interval, but always fails. I noticed that because my speakers were on and they made small static noise once every 5 seconds similar to what you hear when you have your speaker volume up and then plug them in the wall. Sometimes a very dim and short flash of the GPU power LEDs accompanied the noise. Ultimately 5 seconds after I remove whatever device caused it, the power comes back on and I'm good to turn my computer back on.
I haven't had any BSODs, the front panel is working well (4 USBs, audio & mic), the computer is still pretty new (~1 year). Is it reasonable to suspect there might be some shorts in the case or motherboard standoffs are to blame, or maybe a static discharge is somehow causing this?
I plan on cleaning my computer soon, might as well try to fix (or at least detect the cause of) this issue, but I have low to zero experience when it comes to messing with electricity related stuff apart from maybe changing a light bulb.
So any help/advice would be greatly appreciated.
The parts in question are:
Asrock Z87 EXTREME3 motherboard
Corsair RM 850W 80+ gold power supply
Fractal Design Define R4 case
Also just in case the rest of the parts are:
Intel i5-4670K processor, 1x ASUS R9 290 graphics, 1x standard SSD, 1x standard HDD, 2x 4GB AData 1.5V RAM sticks
