EDIT: Lukeno94, just saw your post, sorry.
Well, here's my rationale:
Microsoft, after Windows 98, as we all know, moved to pure NT systems.
They just kept building and building on the old buggy NT code, until eventually they got to XP - which has all of the problems you mentioned above and more. Then they made Vista, which added the Aero theme and a whole bunch of other stuff over and above old buggy XP. And then, as some sort of providential miracle, they got a grain of sense in their heads and released Windows 7, which (at least they claimed) was completely rebuilt. THIS is what they SHOULD have done right after Windows 98, or maybe after the early, super buggy versions of XP. And for Windows 8, the "tablet-style" interface is one of the stupidest things Microsoft ever did (well, depending on who you ask). It just doesn't work on a desktop computer. Windows 10 - perhaps I have no right to speak on that subject since I don't have Windows 10 but it seems kind of more like a marketing thing than anything else. I think Microsoft ought just to have kept perfecting Windows 7 and embraced its status as the "standard" PC OS.
So I've always been interested in old computers but being on this forum lately has really caught me the pc-building bug.
I was in Boise Friday (I live in southern Idaho) and I went to this place called the "Reuseum" (kind of a resale/recycle
kind of place), looking for old computer parts. They had a bin in the back full of motherboards and video cards, labeled
"NOT FOR SALE". I asked the guy about it - and he told me he'd sell me the stuff "$2.67 a pound". Jackpot! I picked out
six pounds of the best stuff and paid $16 for it. So here it all is:
First, the motherboards:

Some Via "eMachines" (bleah) Socket 7 motherboard (looks like late 90's - '98 maybe?). This one boots and everything, works perfect. Came with the processor shown below:

One AMD K6-II 300 MHz processor. Does this mean it's a Super Socket 7 (and the K6-II won't work with a normal Socket 7)?

Here's another Via Socket 7 board, this one seems to be older ('95?). This is one of two MBs I got which have no ports on them, only pins and one AT keyboard port. This one has some caps that look pretty bloated, which is probably why it refuses to boot. I hit the power button and the power supply fan runs intermittently with a quick, set pattern. Any ideas or is that just a capacitor problem? I want to make this board into a nice Pentium DOS machine. I got a whole bunch of breakout connectors for the ports from the local computer store 😀

And another (this time Intel 😀 ) Socket 7 board, with the same problem of not having any ports except AT keyboard. This one also doesn't have an AGP slot, so I can't use it for my DOS machine since I don't have a PCI video card 🙁. Notice the kind of dorky "Mr. BIOS" chip.

This one looks like a turn-of-the-century Win2000-style board (correct me if I'm wrong, which I probably am). Not much use to me since it's missing ISA slots, and appears to have
a Realtek built-in audio (not likely to work in DOS). Might make a nice Win98 or 2000 board for someone, though, so I'll probably sell this one. Can anyone give me a value on it?
Is the "Socket 462" backwards-compatible with Socket 7?
And now the video cards (all of which I know nothing about, but they looked really nice 😀 ):

Nvidia TNT2M64

I have no idea what this card is. Back of the card says "Vertex M1". Can anyone shed some light on this?

A Diamond card. Don't know what it is.

Same deal. Unknown (at least, to me) Diamond card.
Now, since I started this post I headed over to the local computer store to see if the guy could help me with some parts for my planned Pentium DOS machine build. Lo and behold he had a plethora of parts and sold me a whole bunch of stuff for $30:

Pentium A80502100 (does this mean that it runs at 100 MHz?)

Cyrix 686

Cyrix 486 (useless for me since I don't have a Socket 3 system(or whatever 486 uses))
And the big one:

Sound Blaster AWE64 CT4520 ISA. If I'm not mistaken, this should be completely DOS-compatible with the vast majority of games. Correct me if I'm wrong. And does this card need ANY sort of a driver in DOS?
He also sold me a 20GB 7200RPM hard drive, an AT power supply, and a whole bunch of various cords and connectors I'm going to need for the Pentium build.
Anyway, it was a productive weekend. I'll probably sell two or three of those motherboards and make some $$ off of this, the rest of the stuff will go in my "unspecified computer stuff" bin till the Lord comes.
World's foremost 486 enjoyer.
