BSOD on new build - Kernel Security Check, Whea Uncorrectable Error

That is unfortunate news. We've tried so many things and have at most learned that each of them could not detect the true cause of the error. Are we running out of options?

We're not running out of options, driver verifier has quite some options that could be enabled.
If, however, there were no options left in driver verifier, a BIOS update wasn't available, the BIOS was resetted to the optimal settings for the current hardware, all known causes for hardware crashes weren't present on the system, no overclocking was present, no cooling issue was present causing overheating, the voltage values were proper, all cables were proper connected and there was no physically visible damage to the hardware then we would be almost running out of options.

Good news, driver verifier has caused all crashes I've checked, bad news is that no driver is flagged.
This means that the issue isn't drivers, in most cases the issue is a hardware level issue (faulty hardware or voltage issues).
Could you post the following information from the BIOS

1. CPU voltage
2. RAM frequency, voltage and timing
3. 3.3v, 5v and 12v values

Please check your cabling to ensure it is properly connected.

Please don't edit the post, but post a new reply for it. Else I won't be notified about new information what would result in a few days response delay or longer depending on if I remember that there are changes in this thread and how soon you notify us about not having received help after some time.
