AMD K6/2 350

Ok, the other day a guy asks me if I have any older mobos sitting around that I will sell to him cheap (he wants a Christmas gift for a sister who just wants to surf the web). I say I have a K6/2 350. Ok. Cool. I say I got the whole system ready for a $250. He says no, $150 and he will supply hdd and memory. Ok. The guy is a friend. So he goes to the computer show and picks up an 8.4 gb WD hdd and a 64 meg DIMM. I install Win95 (that is what he wanted). I start getting a whole bunch of lockups. Duh. AMD and Win95 have a communication problem and there is a patch. I talk him into Win98. Ok. I keep having problems installing. I go into BIOS and the memory is reading 70ns. Hmm. I put in one of my listed PC100 DIMMs. Reads 10ns. Ok. He got sold PC66 memory (or worse). I put one of my chips in just to do the install. Keep getting crashes. WTF! I put in one of my hdd. Installs fine and runs well. I asked him about hdd. He says, are you sure it is not your board. I have been running pc for months (wife's old pc) and never had problems, but he is a friend, so I try a different pc (same board but K6/2 400 running my NT server which runs 24/7). Same problems. I bring hdd and memory back to him today and say it doesn't work. Now my question is, what did I screw up here. I spent 2 evenings on this stupid machine. Remember, it worked fine for the last 2 years.

What board are you using? If it is via did you install the 4-1 driver?

It is not a Via board. But, I forgot to update since my original post. Sorry, guys. It seems he went to the computer show and got some really good prices on these "awesome" parts. He went back, got some new stuff, and it worked fine. He apparently did have a bad hdd and the mobo was set up to run pc100 memory. Machine up and running and given to my buddy. Thanks for the reply, though.
