In Windows 10 32 bit it tells me my Intel xeon e5420 is 32bit when it's clearly not, the specs to the pc are all compatible with 64bit windows 10 but I get the blue windows 10 symbol and no loading on CD installation. In the windows system it shows as x84 but how?

I believe it to be a bios error but can't see any. The CPU shows as normal with all 4 cores at 2.5ghz each - so why does not work?

I want to try and do a hackintosh and install an apple os on the second hdd but will this solve the problem. It might with different os configurations but I doubt it, Apple is also very familiar with xeons from there imac/powermac and others.

It may be for another reason as well, when I install a graphics card there are no outputs but everything spins and lights up, I tried with various graphics cards but none of them worked. This lead me to believe their was something disabled in the bios for pcie.

There Is a last relevant reason and that's the lga 775 hack in which an lga 771 cpu is customised and the lga 775 socket sides trimmed. Although I don't want this to be immediate conclusion because it is obvious that the cpu Is fully recognised and shows under correct title and spec in the bios. It is also not a good solution to suggest replacing it, the wait and cost don't seem worth it.

I found the answer to one of the problems, as I'm using a Fijitsu board for a pc configured with little customisations the bios Is fairly terrible, it is an older board as well - I'm assuming (roughly 2010 upwards). Ive never heard of this before but apparantly chips in ram can be on both sides or single sided, in my setup I used two double sided then single. The single even when resetting bios (including bios chip removal) did not work and they both operate at 1.5v and only an increase in megahertz of 1033 to 1300. After having looked into phoenix bios problems it was obvious that the error was with ram as I noticed more specifically it was 1-3-3-1 (error 24). The bios updates looked almost entirely discontinued and Fijitsu did give...

Hi,
Pretty sure you meant x86. Anywayz are you sure it's the Xeon e5420? When you right click "This PC" and click properties does it say: System Type" 32-bit Operating System, x64 based processor"? Try installing 64 bit version of windows and see if it works (or Linux). Check the windows event log for possible causes. Try running the windows in safe mode.

Hi, well recommended but on 64bit installation from disc I just get the blue logo. I am certain it is that particular xeon cpu and even so I haven't heard of a 32bit quad core. The fault I really want to correct because of this is my limit of 4gb, there is no display output if I use more than 2gb sticks. I'm using ddr3 corsair value and it doesn't work I get 8 beeps. I fixed the graphic card error because the motherboard has out of date drivers so I scanned the entire Internet for PCI-E root drivers and eventually got there. I'm also planning on doing a hackintosh but this might as well cause problems. Even more oddly is that the entire computer seems to even on a windows repair disc think it'd 32bit. Everytime on boot I get a single microcode error on the cpu, I've never heard of it and apparently you get it after cpu upgrades so I updated my bios. No change. Thanks for quick responses though.

8 short beeps is your motherboard screaming at you your video card isn't working as normal. Make sure it is seated well in the bus. If it still beeps, either the whole card is bad or the memory on it is. Best bet is to install another video card and see if that works. Or use on-board graphics. If you don't get beeps, try installing the 64 bit OS with your graphics card removed.

Good luck.

Already tried your suggestion mbilal2, remember that this is a problem found when the ram is upgraded. Graphic card is fine as I run it well when 4gbs is installed, it's an old 9600gt 3d inno and is tested and working, it is detected on the pc and even when is uninstalled I get the 8 beeps. On-board graphics MUST be working because there are no errors, and the visuals are perfect like any other pc. I looked at the error history in bios in which I discovered from the Internet was possible and found that there is a microcode error related to the cpu. Weirdly I think this is the problem. I also think the cpu Is bottlenecked as it runs mostly at 5%-10% while ram is 80%?!? The solution isnt obvious and I'm fairly knowledgeable myself about building pc's as I have done many (6) and always will for myself and friends. This is a budget pc (made from very mixed parts barely compatible) so errors are likely to be in discrete, it may be good spec but it was only built for £110. Thanks for suggestions so far.

Is the issue only happening when you upgraded the RAM? Cold be bad RAM, could be a bad slot. The other issue is that the system itself is full of possible failure points starting with the fact that the CPU was modded to the old hard drive and motherboard. You are also posting all sorts of issues happening during different times which makes is hard to diagnose anything to a single thing.

You are talking about the CPU showing as 32 bit only, but then state the system does not work with a video card in it. And then about Windows 10 is not loading during setup, so what is installed and what is working?

Does the system work at all, and under what configuration?
What causes it not to work, more RAM or another video card? Does it work OK with the add-on video card on the original RAM (whatever that may be)?
Did you check for a BIOS update for the motherboard if the system is working at some point before you add/change things?
What exactly is showing you 32 bit for the CPU? Or is it just that you used a 32 bit Windows setup?

The bios updates looked almost entirely discontinued and Fijitsu did give me one but not of a better edition. Most disappointingly is that despite being Fijitsu the motherboard runs entirely on Intel chips, this is why I think the lga 771 mod didn't work entirely and had recognition problems, Intel often try to prevent this mod as it would be diminishing of profit (lga 771 xeons are often faster and cheaper as often bought in bulk and more available second hand).
