We purchased a second hand NEC desktop computer and just lately we had a long beep problem that occurred. I figured it might be the RAM, so I disassembled the system unit and cleaned the RAM. However, there is an instance when I plugged it all in again and experienced some electric shocks on the case.
Everywhere I touched has this electricity so I immediately shut it down. I know static electricity might affect the motherboard that's why I am quite worried. I checked the plugs and found out that it was 3 prong plug but the ground is missing. I am not sure if the previous owner just cut it down or it just had a space available to input ground (not sure if this is a thing though).
I am thinking of buying a 3 prong plug and replace it but I am not sure if that would be safe. I am aware that every unit is designed specifically whether it needs to be grounded or not. That is why every single one of them comes with a different plug type.
Would replacing the plug a good idea and will prevent future instance of this issue?
Can someone enlighten me more about this?
Any help would be appreciated. Thanks in advance.
