Windows 10: I cannot find out after hours of research and testing, why my computer keeps BSODing.

I have a computer I bought for 50$ from craigslist. I've had it for a little over 2 years now and it has ran for the most part okay. I had a few issues in the past with it BSODing for no reason but changing the hard drive seemed to work. Well I changed almost every part in it except for the motherboard, power supply, and one stick of ram. I started crashing again when I got my new AMD Athlon x4 87k FM2+ for my gigabyte dual bios motherboard. The stop codes are the same 3 ones, kernel security check failure, driver irql not less or equal, and unexpected store exception (With Kernel Security Check Failure being the most often and most random.) I will randomly get the kernel security error when downloading games or playing them. Sometimes it takes hours for it to blue screen other times it takes minutes. The Driver Irql is pretty rare and behaves in the same way as the kernel bsod but it just replaces it sometimes. The unexpected store exception stop code only happens occasionally on startup and only happens once or twice then doesn't do it again for ages. I'm pretty sure the motherboard is just bad and its not actually issues with my troubleshooting, buuuuuut I need someone else's input that is well versed in troubleshooting.

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Step-by step overclocking in Wattman
Fan speeds
Power limit
Temp limit

Laptop keeps BsoDing after upgrading to Windows 10 *Bad Pool Caller*

I upgraded my laptop to windows 10 yesterday, and ever since my laptop keeps BsoDing every half hour saying there was a bad pool caller. I don't know what to do. I've checked and seen online to install updates would fix the problem, however the windows updater
refuses to find any updates.

What do I do?

 

Computer BSODing

Today i turned on my computer and it booted up fine, but the CPU fan stayed very loud at idle(it should only speed up when its at load.) and Firefox kept crashing. So i decided to just restart my computer, and once i did a BSOD popped up and with a ''Memory Management'' error.

Also keep in mind about a day ago i got another BSOD when i took my computer out of standby, but the BSOD error was ''System service exception''

It not a constant thing though, i can play games for hours and it doesn't BSOD.
