    Give it a go.
    His GPU will be the primary problem with Windows 8. I explained in detail in the post above, but he needs to get a dedicated AGP video card on the later end of the AGP era to have a WDDM driver available or else he's going to have a rough time with the UI rendering or watching videos since he'll be stuck on VGA drivers with that setup he's got right now.
    We all know that a recent OS requires recent hardware but for testing and different purposes even an older machine works well.
    Know your hardware.

    Don't know what's wrong with that adapter. Mine says onboard Intel 256MB and I have WDDM drivers.
    UI renders well and videos are OK. If you tweak the UI enough you can run the desktop on 32MB graphics (there is no Aero check).

    If it's an older model, he can get the drivers running in compatibility mode.
    All latest drivers should be searched (catalog.update.microsoft.com) and installed manually (no exe's) from Device Manager.
    Sure, it worked in Windows 7 because you could disable DWM, use the basic (or even worse, the classic) theme and turn off all the animations and shadows in the performance options. Even if you were using XPDM drivers, you could use an (albeit very gimped) Windows 7 experience. Windows 8 however requires DWM. If you don't have WDDM drivers, Windows 8 uses your CPU to do the desktop compositing tasks instead. That's pretty harsh on a Pentium D. Sure, it will run, but it may not be a fun or even usable experience. His integrated GPU wouldn't have the shader support, and it doesn't even have 128mb of graphics memory. Even with a working driver, it would not handle the demand of DWM on its own. There's no 'classic theme' or 'GDI' to fall back to in Windows 8 like there was before.

    That is where I'm getting at.

    Don't worry about this DWM too much. I've done some tests and on Pentium 3 (1GHz) it's using the CPU as you said BUT not permanently.
    It runs and I assume that a 3GHZ cpu will be better. Look on the update catalog site and see if there are WDDM drivers.

    If it's the only hardware you got or if you want to test the OS you can give it a try on a Pentium 4 why not.
    His graphics adapter has a chance with the latest drivers provided be it WDDM or compatibility mode.

    Sure, it will run, but it may not be a fun or even usable experience
    Agreed. But sometimes you need to try and test it yourself.
    Of course it's not the same as on Ivy Bridge motherboards but it will run. Don't worry.

    Why bother? This isn't 2005. You won't experience 8, you'll grind through it. Its 2012, get a modern PC that will be at least three times as fast and use half the power. Most phones are faster than the OP's system.

    Cool thanks for the help, the AGP cards that Lazure recommended would be a pain to find but I'm pretty sure if I go to an antique computer parts store or anything similar I could probably get a 128 MB tops.

    Hey guys, I just ran the Windows 8 Upgrade Assistant and it said my PC is okay but some of my programs (Daemon Tools, Adobe Air, etc.) also it said that NX is not enabled or not available on my Motherboard the same goes for secure boot. Now I have been looking it up but I can't seem to see anything that says my Motherboard supports NX. It supports PAE and SSE2 by default though.

    You have to see if you can turn NX on in the bios.
    ...........Microsoft says: If your PC doesn't support PAE, NX, and SSE2 you won’t be able to install Windows 8. Upgrade Assistant will provide you with an error message if your processor doesn't support PAE and SSE2. You'll also see a notice if the processor might not support NX or if NX is turned off in the PC BIOS. Windows 8 Setup will attempt to turn on NX during installation and, if it isn't able to, will return your PC to the current operating system. What is PAE, NX, and SSE2 and why does my PC need to support them to run Windows 8?
    As for secure boot..... mine doesn't support that either....and I'm quite happy about that.

    PAE or NX should be the same. Look in the BIOS to be completely sure it's available or not.
    Upgrading is always more difficult and the minimum requirements are higher.

    Choose the ISO in the upgrader option and do a clean install. A clean install works on a Pentium3 Coppermine with PAE, 512mb RAM is enough and you don't need SSE2! It should be OK on a Pentium4 (D).

    I already tested the clean install (works!) on Pentium3 and don't want to argue about these low specs.
    The Pentium3 didn't had any PAE option in the BIOS, it was by default enabled. How did I found this: by installing VMware Player 3.1.5
    On a even older CPU (P3 733Mhz) the VMware installer checked and came with an error during installation saying no PAE.
    On the Coppermine (1Ghz) it installed without problems meaning PAE was available.

    SO if your BIOS has no PAE or NX options, try installing VMware Player 3.1.5 (no 4 or 5 that are x64 aware). If the install succeeds, then the Windows upgrader is just not allowing the install because it needs even higher specs. But the clean install might fix the problem.

    Good luck with installing.

    PAE and NX are *NOT* the same thing, they are totally unrelated. PAE is a technology that lets a 32 bit OS use more than 4GB of memory (although desktop versions of Windows do not support this, server versions do). NX is the No eXecute bit, that allows the OS to mark parts of memory as data, and not executable. This helps prevent security flaws from being exploited.

    Sorry for my ignorance. I was comparing it to VirtualBox where both settings are enabled with one checkbox (PAE/NX).
    But not all BIOSes are alike or even have all options available.

    My machine was supposed to have enough firepower to run W8 and theoricaly meets the requirement, yet it refused to install or run because of more complicated reasons, not mentioned in the requirements (some BIOS and processor option, in my case). In one word W8 refuses to work on some old computers it deems too old for him. Please test the Release preview before purchasing.
