Default Blue screen error BCCode 1a

After building my new computer its feeling quite unstable.. all parts new and first time using.

Its crashing then having a hard time booting back up. After a crash the Mem OK LED with be solid and only after flashing Bios will it load into windows again.. it will either have a quick freeze followed by a crash or go to blue screen

I wanna say that is a memory error of some sort... Run memtest 86+ for a few passes and see what's up.

Can you go to c:\windows\minidump and grab the minidump files from the last 3 days, put them in a ZIP file, and upload to a hosting site?


This will help determine if it's a system driver/file causing the issue since you passed memtest, though, I have seen both errors from bad memory in the past, as they are usually related to access violations of some form.

Also, can you list the full specs of your computer, including your OS?

It's a problem with your memory or the memory controller. I'd say your running hot, or your cpu is going bad, or your memory is defective.

You need to run memtest through the complete test at least twice but I would let it run 3 times. I've seen plenty of memory that could pass the first run but fail in the second or third run.

I would investigate a heat issue 1st. Post some screenshots of CPU-Z (all the tabs) and HWMonitor.

CPU-Z v1.58

HWMonitor v1.18
