If the outlet is actually connected to ground, it should be ground. It might not actually be grounded, especially if it's an older house.

Nope, not at all, it's just that, since not all of the ground pads need to make contact, as they're all connected together, and since the middle screw is the most tedious to screw in / out, they just thought of getting rid of the middle hole altogether and putting a permanent standoff

Turns out the ground isn't hooked up. The entire house isn't grounded. So this issue has probably always been here but just became more noticeable once I got new speakers and an audio interface to connect my guitar to my pc(all metal on guitar becomes electrified as well). Made arrangements with an electrician to try and get this sorted out without having to run all new wiring throughout the house...

 

Thanks for all the help everyone.

So I have determined that my computer itself has a grounding issue. Grabbing anything that has exposed metal results in a tingling sensation in my fingers and this continues through all peripherals. I've tested multiple power cables and outlets. Not sure what else to check before I just swap the power supply. Any suggestions?

Can you tell us the PSU model? Might be a good idea to just swap it out if it's an old / inadequate component. Also, have you checked whether the PSU shroud is able to make contact with the metal of the case?

Seasonic SS-760XP(Platinum 760) It's snug in its place, all the way to the bottom and back of case, I'm not really sure if that's what you mean though

How can I check this on a fully assembled computer without removing hardware? This machine has been stationary for about 2 years now

Ok that's a very good PSU, I probably wouldn't change that. Regarding the positioning, just check if the metal shroud of the PSU is touching the metal part of the case or if there's air gaps or some rubber or plastic isolating. If it's snug and thoroughly touching, the PSU is not the problem.

Do check for this, but in theory all of the ground pads of the standoff are connected to each other, as that's the very point of an electric ground. But still, does no harm to check that too

Just open up the side panel, grab a flashlight and look at the 6 (9 if it's a very big motherboard) spots for the screws and see if the motherboard is bending (no standoff) or if some screws are missing altogether

I have it hooked to a surge protector and then to a 3 pronged outlet which I think means it is because bottom prong is ground?

I can see there's mounting screws, but the standoffs are between the board and the motherboard tray of the case so these pictures don't show them.

It's impossible for me to get pictures of them I'm not going to disassemble the pc I'm currently using lol if the screws are there then the mounting screws have to be otherwise theyd just fall out

you could just look from the other side of the case, the board should have some distances (usually 1cm) away from the motherboard tray.

Found the missing screw, it's in the very middle. It could have fallen and shorted smth out or just the fact that it's missing may cause the grounding problem. Start by searching for the missing screw

Yeah I was wondering if that was it. The bottom is there just not the head evidently

Newer (last half of a decade or so) cases have the middle mounting screw replaced with a pin. This makes it easier to alight the motherboard when assembling the PC.

So it could just be the board isn't compatible with the case itself?

Ohh ok, didn't know about that. Never noticed that feature in a case IRL, but now that I think of it I may have heard of that. So there may be no missing screw at all.
Which would explain this:
