I just had a weird thing happen to me. I turned on my computer (computer has been working fine for about 8 years) and I guess the power supply blew as I heard crackling noises and smoke came out of the power supply (the part where the fan is attached.) My hand was laying against the desktop when I turned it on & I guess I got some sort of shock when it blew as my hand is tingling and 3 of my fingers feel numb. The computer is an old Pentium II so I guess it is time for things to go wrong but this was kind of scary. I quickly grabbed a towel and unplugged it then took it to the dumpster.
LOL....You painted a good picture for my warped sense of humor.Hope you are okay.
I saw you unplugging the towel and taking it to the dumpster.
With an old pentium II you could pick up a new power supply very cheap.

No, I was not going to mess with it. I have a new computer, but still used the old one on occasion as I have alot of old Windows software. I am ok & my fingers are starting to get back to normal. Weird experience though, I have never had a power supply do that.

My brother's went - he said it sounded like a gunshot.
I opened it up to have a look - a solenoid core (iron cylinder) had fired up from the circuit board and had glued itself to the inside of the PSU housing.
Lots of energy in there

my neighbor heard a big bang when she powered up her PC also after not having it on for 3 months (it was unplugged for that time). It had a dust cover on it. Funny that there was no smoke or noticeable damage to the power supply, but all worked fine when I installed a new one for her, thank goodness her MOB didn't get trashed too.
Hopefully my advice will help you...Please post back with your results....thanks

If your hand was tingling while touching the case, it sounds like it wasn't the PSU's fault, but rather an ungrounded electrical system in your house. You really ought to get your electrical wiring updated if it is indeed ungrounded.

By not being grounded I assume you mean I don't have the 3 prong socket in the wall? If that is what you mean, you are right, I do not, but I have the computer plugged into a surger if that helps?

Surge surpressors don't ground whatever is plugged into them if the wall outlet isn't grounded.

Replacing the PSU would probably involve removal and replacment of the connection to the MOBO and removal and replacement of the power switch.
It usually means almost disassembling and reassembling the computer.

Hi, Your AC outlet is not grounded? If it were you would have only blown the circuit breaker for that outlet. You would not have been shocked. That's the purpose of the ground - to protect you.
GET IT CHECKED OUT!
Good Luck, Jim

At least have someone connect a wire from your PC housing screw to a grounded metal pipe in your home. The pipe can be confirmed grounded by useing a test meter between the AC outlet and pipe. If it'll show 115volts the pipe is grounded.
correct me if I'm wrong
