Here is what happened to the Duron: the case I was given was called an Elan Vital, and it was really meant for something like a Slot 1 system. It had a pretty cheap PSU, and it had no rocker switch. I had taken the SDRAM out to use in another motherboard I was testing out to build a system to give to my aunt, and I forgot and powered on my main system with no memory. That Soyo board had a feature where it would "talk" to you through the case speaker speaker and it said "No memory" and I realized my mistake. But; I had only had an ATX case for a couple of weeks, and I was still used to AT cases with their positive on/off switch. I hit the power button to turn it off, and nothing happened (I didn't know that you could hold the switch down and it would eventually turn off) so I didn't know what to do. As I mentioned, the psu didn't have a rocker switch so I did the only thing I knew to do, and pulled the plug. I then installed the memory and turned it back on. then I noticed that I had no sound? This board only had one ISA slot, and I needed that for the modem, so I used the onboard sound (which was not as good as the Creative AWE32) and it didn't work now? Then I noticed that when I tried to start Jane's WW-2 fighters, it would CTD?
Based on this, I was sure it was a bad motherboard. It seemed that the voltage spike from unplugging it did some very selective damage. So I ordered an Abit KT7A from Tiger Direct, mostly because it had an ISA slot and I wanted to stick with that ISA hardware modem for my dial up internet. Then I got that board, but I discovered that the CPU had also been selectively damaged, and even with the new motherboard I still couldn't play Jane's WW-2 Fighters! It would mostly work normally, but not for games.
So then I bought an Athlon 900 on Ebay, R.I.P. 700 Duron. But then I had a new problem. Everything was working fine, but the Logitech Wingman Extreme joystick I had came with software you were supposed to run with Windows 98. Maybe you could have just installed the driver, but if so I didn't know that then, so I would install the software and then the joystick would work correctly. But now it would lock up the machine? So I returned that CPU, and the seller sent me another, and it had the same problem!? Then I found out that the old version of the software was speed sensitive - if your CPU was too fast, it would lock up the machine! I had to download the newer version, which took a long, long time at 26.4k. Yes, that's right, the phone lines where I lived meant that anything faster than a 28.8k modem was wasted. I was very apologetic to the guy I bought the 900 Athlon from, I had no idea that you could have a CPU too fast for the software. I believe I also did the pencil trick on that Athlon.
