Same for both links.<br/><a href="http://windows.microsoft.com/en-us/windows/preview-iso">http://windows.microsoft.com/en-us/windows/preview-iso</a><br/><a href="http://windows.microsoft.com/en-us/windows/preview-iso-update-1504">http://windows.microsoft.com/en-us/windows/preview-iso-update-1504</a><br/><br/>Don't understand why it won't install on the Dell Optiplex GX520. Try the Windows 8.1 compatibility checker.<br/><a href="https://www.microsoft.com/en-us/windows/compatibility/CompatCenter/Home">https://www.microsoft.com/en-us/windows/compatibility/CompatCenter/Home</a><br/><br/>Do you get this message?<br/>,I stand corrected. <br/>The build is 1074, not the new version MS is testing.<br/>It runs well on My Dell Optiplex 745. <br/>It does not on the GX 520, the PC of this topic. <br/>Apparently it is not BIOS bug.<br/>It is a CPU shortcoming. <br/>(I mean it is for the 64 bit version, Using 32 bit there is no error reported. CPU-Z says it is a 64 bit CPU and will run 64 bit stuff.)<br/>I have been on this most of the day. <br/>Tomorrow I will show pictures. <br/><br/>First of all, thanks to all. <br/>Next, I must apologize for my memory failure. <br/><strong>No, not the PC, my brain.</strong><br/>I should have remembered that I did this before.<br/>But somehow I read something that made me <a href="https://interviewquestions.tuteehub.com/tag/thin-707663" style="font-weight:bold;" target="_blank" title="Click to know more about THIN">THIN</a> it was BIOS.<br/>Really, if you want to run modern OS and Apps on a PC, it has to be unit made in the past few years. Specifically, 2007 onward. <br/><br/>However, Windows 8.1 32 bit will run on older systems. Photo attachment 1.<br/>With regard to the Dell GX520:<br/>But Windows 8.1 64 bit will five an error message. Photo attachment 2.<br/>(Windows 10 preview gives same error.)<br/>Using the right Windows 8.1 adviser the detail shows. Photo attachment 3.<br/><br/>This is the end of this. <br/><br/>[attachment deleted by admin to conserve space]Quote from: patio on May 10, 2015, 11:29:24 AM<blockquote>With a 9 year old PC you cannot exactly expect Win10 to co-operate...just sayin...<br/></blockquote>I still don't understand why the actual CPU Model numbers on these systems has yet made an appearance.<br/><br/>Find out the CPU model and verify it has the necessary <a href="https://interviewquestions.tuteehub.com/tag/instructions-1046362" style="font-weight:bold;" target="_blank" title="Click to know more about INSTRUCTIONS">INSTRUCTIONS</a> for the OS you are running. You would have saved a lot of time.You are right. I went down the wrong path. <br/>The model is Dell GX 520<br/>The Mobo is Dell ORJ290<br/>CPU is Intel Intel Pentium D 820<br/>CodenameSmithField<br/>Socket 775 LGA<br/>Technology90 nm<br/><br/>NorthbridgeIntel i945P/PL/G/GZ rev. A2<br/>SouthbridgeIntel 82801GB (ICH7/R) rev. A1<br/><br/>The info above is not clear to me. But it is the CPU not the BIOS.<br/>Next year I will buy a better computer.The Pentium D 820 doesn't support the PrefetchW instruction. <br/><br/><br/>Furthermore, while it supports the LAHF/SAHF instructions, there is a bug in the CPUID instruction of some stepping which fails to report this capability in 64-bit mode. PrefetchW is also a 64-bit requirement. It is not a requirement for 32-bit.<br/><br/>The "5D" error is because the NX/No Execute instruction is not enabled... Salmon Trout mentioned this already.<br/><br/>The prefetchW error is odd <a href="https://interviewquestions.tuteehub.com/tag/given-473447" style="font-weight:bold;" target="_blank" title="Click to know more about GIVEN">GIVEN</a> that prefetchW has been a No-op instruction on processors that support it for some time now.Thanks to BC, Salmon trout and others who helped.<br/>I should have remembered this. Because I was using the 64 bit Windows 7 with no problems, I found it hard to understand how something was missing.<br/><br/>But I am not the only one. In fact, Microsoft has a hard time explaining all the issues that have come up with other instructions that a missing. An the year of manufacturer is not a guarantee of qualification.<br/>Looking back, more problems came up when MS went from Windows 8 to 8.1 with a new list of requirements for the CPU and the chip set. This was documented earlier elsewhere, but I missed it. <br/><a href="https://www.pcworld.com/article/2058683/new-windows-8-1-requirements-strand-some-users-on-windows-8.html">Windows 8.1 and new woes.</a><br/>It would have been easier to provide tools that would give more information about the issues. As BC mentioned, the CPU I have also has other things wrong. IMHO this information, if widely know, would have started a riot in the PC marketplace. (See PCWorld link above.), <br/><br/>Some quad-core CPU s were made and sold years after issues were know to exist in both Intel and AMD designs. There was never a product recall.<br/><br/>We are talking about the 64 bit system software starting with Windows 8.1. This is not a problem with the 32 bit version of Windows8.1 now available. Just Google it and find a sites that offer the 32 bit version of Windows8.1 free trail.<br/><br/><em>So, I have been beating a dead horse.</em> Quote<blockquote>So, I have been beating a dead horse. </blockquote><br/><a href="http://gifsoup.com/view/1767326/guy-punching-computer-screen.html">http://gifsoup.com/view/1767326/guy-punching-computer-screen.html</a><br/><br/>sorry feeling <a href="https://interviewquestions.tuteehub.com/tag/kind-25540" style="font-weight:bold;" target="_blank" title="Click to know more about KIND">KIND</a> of funny today. <a href="http://www.nydailynews.com/news/crime/fed-colorado-man-arrested-shooting-dell-computer-8-article-1.2193507"><em><strong>Solution Here...</strong></em></a>Poor Dell <br/><br/></body></html>
