the mrs is saying just send it back
I'm with the Mrs on this one
There are a lot of possible causes for this fairly common error, and solving it is a long series of doing & testing—unless of course you get lucky and find the culprit quickly.
If you did any customization in BIOS, use the 'reset to defaults' option.
Disable all power-saving settings, turn off 'performance mode', disable any overclocking, unplug any attached peripherals except KB & mouse, disable as many Startup apps as possible—you want a plain vanilla simplest setup to start from, so eliminate as many variables as possible.
Boot from something—eg recovery USB—other than the system drive, in case it's dodgy.
The likeliest culprits are drivers, this error most often results from two drivers competing for memory resources. Could be any two.
You could try WhoCrashed
, it's a good tool which might identify the problem.
Go into Device Manager and look for warning icons—resolve any warnings & test. Then make a list of all the devices you know about—ie ignore stuff like System & Ports. Go to each component manufacturer's site and download their latest stable
driver. Now in Device Manager, uninstall each existing driver & then install the new download—doesn't matter if it's the same version, the old one might have a small corruption.
If you want to test RAM, get MemTest86
—it'll take hours, so it's an overnight job.
If drivers don't solve it, next is to disable all devices in BIOS except KB, mouse, onboard graphics and system storage—sound, network [wifi, lan], etc, turn all off. If PC runs well for say an hour, re-enable one device and test for another hour. Repeat until it fails—last item you re-enabled is the culprit.
Next physically remove all components except motherboard & RAM & system disk—I assume mobo has on-board graphics which is turned on in BIOS. If PC runs well for say an hour, install one component and test for another hour. Repeat until it fails—last component you installed is the culprit.
