About a week ago, I was messing around with my computer and ended up getting the famous Blue Screen of Death. I am taking a shot in the dark posting on a forum. Maybe it should have been the first thing I did. I have probably spent the past 48 hours solid (my only two days off) attempting a fix. Anyways, here I am.

I have the errors written down somewhere, so they may not be verbatim what the errors are called.
The first happened when I restarted my computer
- Page_Fault_In_Non_Page_Area
The second happened when I attempted to use the Windows repair function
- Multiprocess_Cores_Not_Supported

After a quick Google search, I do believe these are hardware errors. Correct me if I am wrong, but it sounds a lot like it could be only a few things. I will just cut it down to the three that I, with no formal computer education but a strong grasp for search engines, believe to perhaps be at fault.

#3: Memory - x8 1gb DDR2 ECC
Computer repair store I went too was totally useless. Told me the memory was bad, maybe. He did not have any ECC RAM in the store, and could not help. Well, I took out all the memory CAREFULLY and cleaned them off. One at a time, I reinstalled the memory. After I manually checked it out booting one stick at a time, works? shut down, install another, etc, (Again, literally no training or anything) I run every memory test I knew about, and they all come back with nothing to report.
No news is good news? No. I wish this was just memory, I would have bought new RAM on the day this happened. It's never that simple, is it? Just my luck, in a week I will figure out it is the memory.

#2: Drivers
I guess this goes with both #1 & #2. I rolled back some drivers, but since then, I have done an entire reformatting for both my hard drives. Now my smaller 128gb hard drive is running Ubuntu (So nice out here on 16.04), but again this is Linux, I cannot run the applications I used too. I can run a copy of Windows 10 I recently purchased from Best Buy in a last attempt, and when I find where I left it, im sure it can run Windows 7... x32 bit OS. THIS MEANS:
- only 1 processor
- only >4gb of RAM (approx 3.25g RAM available)
- and just a incredible headache from the amount of lag I have even opening up a different <i>'Microsoft Edge'</i> page.

#1: Core0 & Core1 have different stepping values.
I have had this desktop for nearly over a year. It has been running Windows 7 x64 that entire time. I have never gotten the Multiprocessing_Cores_Not_Supported. Reading into it, Windows apparently only supports 1 core. After spending a rather absurd amount of time attempting to understand it, I think it means, "Your cores cannot be one bit different." I'll attempt to show this in colour. CPU0 can remain black, while CPU1 can be blue.

BIOS Processor Info
Type: Intel(R) Xeon(R) CPU x5450 @ 3.000GHz
Clock Speed: 3.0GHz
Bus Speed: 1333MHz
L2 Cache: 12mb
ID: 00010676 ID:0001067A
Family=06 Model=17 Stepping=6 Stepping=A
Microcode Version 0000060F I00000A0B

I am convinced the issue is these different values between CPU0 and CPU1. I mean, it has to be. Windows cannot support this anyways. How did I get away with this for so long? It seems like one of the CPU drivers fell out of sync with the other, but only very recently.

But why now, after so long of working? And why can I not revert back? Did a malicious little virus change my processors info so they cannot be used? Do they need to be updated?

I have read 'stepping' are like versions for software makers. Can I update these drivers somehow to get them to work together?
 
Solution
Do both versions below and we see how to fix this.

Short version: Download and run this: http://www.resplendence.com/whocrashed
it scans error logs and may show us cause of problem

copy/paste results in here.

Long version: Can you follow option one here: http://www.sevenforums.com/tutorials/174459-dump-files-configure-windows-create-bsod.html
and then skipping stage 5, do stage 6: have Windows Create a Small memory dump (Minidump) File on BSOD

this creates a file in c/windows/minidump
copy that file to my documents
upload the copy to a cloud server and share a link here

someone who can read the logs will help you. I can help with short version but can't read logs yet :)

I assume that you are referring to two seprate CPUs with different stepping values. (dual cpu, with x number of cores each)
stepping values of the processor should not be a issue, these are fixed in BIOS and in a .dll loaded when windows boots just in case you do not update the bios.
\SystemRoot\system32\mcupdate_GenuineIntel.dll Thu Oct 29 19:42:26 2015 is the intel version of the microcode updates.

generally only server machines would use ecc memory desktop machines do not because of the added cost in hardware.

so what is at actual make of the machine?
do you have any memory dumps to look at?

I do think windows 7 and above would support 2 CPUs and would require custom changes for more than two cpus.
