Duron Destruction?

My bro is buiding a system for someone, and asked me for advice. He picked up the Abit Kt7 non raid version, and a Duron 700 w/ the hs from AMD. He had a sweet full tower case, but the power supply is 235 watts. I told him to pick up an approved 300 watt for future expansion. To make a long story short, my bro uninstalled, then RE-installed the 235 watt ps, thinking he had put in the new one. (Only my brother....) Anyway, the machine booted, got to the prompt for the bios, and then !poof! lights out. AFTERWARDS he comes to me, I figure out he has the wrong ps, and after troubleshooting as best I coudl w/out another board or chip, I can't get it to boot. Could an understrength ps zap the board or the chip? I have tried 'bout everything, and he is going to take it to a local shop that has other boards/chips to see which got whacked, but I didn't think either of them should have met w/ death over a ps????
 
I'm using a 235W PS on my fully loaded system with a Duron600@950Mhz and haven't had any problems. Maybe something touches and shorted out. I doubt that an underpowered PS will kill a processor.
 
LOL...I wouldn't worry about it Caitiff. When I first received my KT7-RAID and TBird 800, I couldn't afford a 300-watt power supply till the next week. Well, needless to say, I was pretty excited, so I decided to see what my 145-watt power supply would do. It wouldn't boot, and the couple of times I did get it to boot, it wouldn't POST, and would lock up when trying to save and exit the BIOS!! So, don't worry, it wasn't the power supply, definitely.
 
Thanks for the replies. I didn't think the ps would trash the system....
I think it was becouse he didn't mount it using the paper washers as spacers. The mobo tray has raised bumps w/ pre-drilled holes to mount the board, so I think maybe the board shorted. It's a little odd that it booted at first, got to the 'press del to enter bios', then died forever. <shrug> Guess we'll find out when he takes it to the shop. I tested everything I could myself, even pulled the battery and shorted the cmos jumpers to see if it was just a flaky bios problem w/ no result. All I wanted to do was OC that sucker! It was a 700Mhz, and the L1 bridges were closed! I was going to go for the big GIG! 🙂
 
I agree on the mobo short maybe, but also:

What cooler did you have on the chip? Did you verify that it was seated properly? Did you forget to use thermal grease or TIM? I am guessing it might have been a cooling issue. It was stated that it takes 8 seconds for an uncooled thunderbird or Duron to reach critical temp and &quot;bye bye&quot;.

Kyle over at [H]ardocp knows all about that. He put an alpha pep66 heatsink on his and did not remove the feet. No contact. No cooling. Poof!


 
I checked his setup on this count. He was using what looks to be the generic fan from AMD, minus the blu-tac stuff. He wasn't using any kind of hs paste, which I rectified for him. He had it locked down correctly on the processor, and it had good contact w/ the core. I don't think that it was a heat issue....
