I was swapping an a: drive, with the computer running, and as soon as I hit the power connector to the pins on the back of the drive, there was a spark and the PC shut down and will not come back on. I know that I shouldn't have been doing that with the power on, but was wondering if I have fried a power supply (or worse)? Any ideas?

You could have fried the power supply, and you have probably fried the motherboard and memory. The componenets on the motherboard and memory only take the slightest electrical discharge to become damaged. Sorry to have to break the bad news to you.

The power supply works still works (I finally put it in another computer), so you were probably right on in saying that I killed the mobo and the other components. Do you think I killed the processor too or just the RAM?

CAUTION: Hazardous voltages are present.
Unplug the power supply and allow it to sit for several hours before proceeding.

If you are lucky, the power supply has an internal fuse, and all that has happened is that the fuse has blown.

Here is a link to a Tech Republic article on replacing the power supply fuse.

I pulled the power supply and checked the fuse, but it is still intact. I guess I have probably killed the mobo and everything else...Thanks anyway!

sorry just had to say LOL

Made me remember doing this about 15 years ago on one of my first pc's.

Hopefully it is just the power supply which are cheap. If you replace and it is still inop, it has more tan likely fried your mobo also.

Good luck.

Well, the power supply still works after putting it in another computer. I should have known to do this at the very start, but oh well. Thanks anyway!

It appears you blew your power supply. I do not think the mobo is blown. You can check for fuse in supply if you want but the time and effort is best spent buying and installing a replacement power supply. If it is the fuse you would have to do some soldering to replace it. It may be a component in the P/S, not worth the effort based on the cost of a new power supply.
