Worth to mention:
I live in a very old building that does not have any kind of electrical grounding. Everytime I touch metal part of a connected electronic device, mostly my computer, it shocks me. The shock is not hurting, instead, irritating. I sit on carpet while disassembling my stuffs.
Story:
Suddenly my PC wont turn on anymore, lets call it PC_1. So I start removing part by part, from memory, vga, hardisk, cpu, down until only motherboard and psu connected. Still won't turn on. Curious, I took another computer, lets called it PC_2. Removed everything but the motherboard and its psu. Now, I start putting in cpu, memory, vga, hardisk from PC_1 to PC_2 one by one, turns out, they are all works without any problem.
Again, curious, I put away everything from PC_2. So now there are only 2 cases, and 1 set of hardware.
Result:
Assembled everything in PC_1 case: wont turn on, no led, no beep, no nothing
Assembled everything in PC_2 case: works, no problem
Both cases shocks me when I touch any metal parts of it. Small shock, barely noticable; in some places though, strong enough it stings a bit.
The only differences between each cases is the motherboard standoff. PC_1 case have built-in standoff (welded together along the case), while PC_2 have standard removable standoff.
Question:
1. Relating this to my grounding condition, how is this happen?
2. How come it works before?
3. Someone have similar experience?
4. Is there anything like DIY grounding tricks without major electrical work with that copper rod and such.
Thank you
