What component did the smoke come from?

All i can recommend is to plug it back in again, then try to turn it on.  If it does not turn on it is either the PSU, mobo, RAM or CPU that has gone.  It sounds to me like the PSU has gone, as they are known to smoke a bit when they give in. 

If it does not turn on when you try it, try getting hold of another PSU from somewhere and put that in, i would make sure it is a good quality 350W or a reasonable quality 500W, so that you don't blow it.

If it does turn on but no picture, then it is obviously your GFX card.

Ok then there is only one way to find out which it is, plug it in turn it on.  It will not work at all if the CPU is broke, it will turn on and no picture will appear and loads of beeps will occur if it is the GFX card.

Not neccessarily...I had a problem just last week where when I turned it on I didn't get anything on my screen and my mobo didn't beep or anything...led me to believe cpu, memory, or video card...but all tested good in a different system...so I started swapping parts and found that my power supply wasn't workign quite right...after rigging up a temp setup to test the power supply I found that the voltages weren't what they should be...replaced p/s with a new one and am up and running with no problem... I'm still not sure why I didn't see any smoke pouring from the p/s...

Iroquis, excellent presciption!  Vanilla Blue Bell, Hersheys Chocolate and M&Ms!  Coupled with sleep, all problems fade away...

Drats.  My system worked before, and I've never heard of RAM failing, so scratch one possibility.  The GFX worked fine on the Dell PC, and I turned it on today, and all the mechanical things (fans, lights, etc.) worked, so the motherboard is distributing power.  It must be the CPU.

Is AMD a customer friendly company?  Would a CPU failure like this even be covered under warranty?  Bah!  I like my money!

Have you actually tried another power supply?

I seriously thought that my cpu/motherboard or everything was toast this past week...I was too getting power at the fans, and the voltages all added up where they were supposed to...

Just a thought, but if I were you I would try the $40 p/s replacement before waiting a month for amd to set you up with another one...

and if the p/s help any you should be able to take it back to the store right? most places do have return polices...

Its not exactly the morally right thing to do, but, I'd order a replacement cpu, when it arrives, mail your dead one back, if your lucky, you'll get either a refund or a new cpu. I've been there, done it and got away with it!   

Before you re-fit it though, find out exactly what caused your cpu faliure to start with!

He didn't do anything wrong unless he did what Ivan said.

He should get into contact with the manufacturer. I think it's an AMD.  See what they can do. Unfortunately customer service is pretty bad. I still have a copy of LOMAC I can't get rid of because it won't run on my computer. It's really hit and miss. He obviously can't contact the store.

I can relate to you Scorpion. I went to a rather unknown computer store in Burlington, Ontario. They were offering a cheap setup. An AMD Duron 950 with a K7S5A mobo. It was around $300 for the two including installation and tax. That's when the Duron still pulled it's weight. When I took it home the computer kept freezing. I took it back to the guy, he claimed he fixed it but it started freezing again soon after. I took it to a guy in town here. He said who ever installed it did a terrible job. The main power cables were hanging dangerously close to the fan and the mobo wasn't securly fastened to the case. These guys had also forgotten to reinstall the OS which is a must when installing a new mobo. Needless to say the thing burnt out after less than a year of use. I got a new K7S5A to replace it from a local dealer and I've never had a problem since.

LOMAC is Ubi. My problem was with EB Games though because they wouldn't take it back even though it was still within the 30 day return period.

Not sure but I think its only Retail AMD CPU's that have any warranty.  You must be using the retail heat sink that came with the CPU too.
