yea its proprietary and yes i have a couple of the same power supply's laying around and the cd does work in other machines

Yeah, I think the Dimension 4100 has a proprietary PSU. I'm not sure how to check, other than maybe open it and check it for bad caps? Start with checking the BIOS defaults and see if there is an OS Type setting in the BIOS. I'm just throwing out ideas. 😀

It does, you can buy adapters from Ebay if you want to use a standard PSU. They are only $4 🤣

Really i can buy an adapter do u have a link as i dont know what there called

I've got one in storage with a Pentium III 866 (or a 933, it's been a long time since I've played with it), 256MB of ram, and a Radeon 9000. It runs Windows 2000 like a charm. It's easily one of my all time favorite OEM systems.

Thats awesome im getting one^^^

So i just switched out the 1ghz and put in a 933mhz and its now installing windows 98 either the motherboard dont like the 1ghz p3 or cpu is crap, ive had lock-ups here and there when i used that 1ghz p3 in my hp, i dont really understand why this cpu is bad though.

Thanks for every ones input

That's interesting. What cpu originally came with the system? Was the 1Ghz cpu a 100 or 133 FSB?

the one that come with it was a 933mhz 133fsb witch i put back in, the one that was bad was 1ghz 133fsb.
I thought if cpu where bad that they wouldn't boot at all.

It's possible the cpu is okay, but the chipset is just flaky enough that it struggles to stay stable at 1Ghz. I know the 4100 should be able to run it, but it's an old system, and maybe pushing it closer to its limits exposes some instability that maybe wasn't there when the system was new.

Then again, maybe the cpu is bad. 😉

I have noticed that some of these P3's are different voltage. I have both 1.6 and 1.7 volt 800EB's for example. Perhaps see if using one with a lower voltage would help. Also you could try popping in a Celeron.

both the 1ghz and 933mhz are 1.75v
Thinking about trying this out http://www.ebay.com/itm/Tualatin-P-IIIs-1-4GH … Q0AAOxyRhBSxjSY

It was the CPU? Wow, that's unexpected, but glad you figured it out 😀

The chipset on that board is 815, right? This is not specific to any M/B model:
www.cpu-upgrade.com/mb-Intel_(chipsets)/815.html
but the 1.0, 1.1GHz CPUs may not be supported by all boards at release. (P3 1000/133, 1100/100 aren't even listed there, I wonder)

So maybe a BIOS update is needed.

A suggestion maybe, is to put the 1GHz CPU back after Win98 is installed and see what happens?

i did put the 1ghz back in and it freezes when i open anything and i do have the latest bios

Interesting solution, got a Dell that gave me this trouble and it would start installing xp only to lock up a third of the way through. Didn't care too much about it and put it away in the closest.

i will post back as soon as i get my tulatin mod adapter in a week, im very curious if it will work, most likely it wont but i do have another machine that it will work in if not.
That will tell me if it just a junk 1ghz cpu or motherboard cant handle past 933mhz.

Did you have a 1ghz as well?

I've never met a CPU in my life that's "half-working". 😀
