MemTest x86 spewing lots of errors

Hello, I have been having problems with my computer since yesterday, I figured out it is due to the bad memory.

I am running the memtest right now, it's at 75% of first pass, and I have got 152 errors so far, all mentioning CPU 3. (Will add an image later)

Does that mean my RAM is bad, or that one core in CPU has gone crazy?

It might not even be a faulty chip. You can try reseating the components in their sockets.

Well, tried that... Except the CPU.

I haven't been able to boot into windows yesterday. After pulling out sticks in slots B1 and A1, it was working, but then it crashed - GPU was displaying frozen picture of prime95, and it wasn't reacting to mouse or keyboard.

I haven't moved the cpu since I built the computer.

-----
Just a moment ago, another error popped up, mentioning CPU 0.

Try with 1 RAM stick at the time? If 1 passes the tests it is probably not the CPU, and you can try to boot Windows with that 1 stick. Then tests the others 1 by 1.
If all fail 1 by 1 it is probably not the RAM.

Also, if every stick fails in one slot, try an adjacent slot: it could be one memory controller in the CPU is shot and the other still works.

If you've been using XMP or otherwise overclocking your memory, try turning that down a notch.

Check temperatures in the BIOS setup if possible, as a fallback when the OS won't load or isn't stable enough to use OS hosted applications to check sensor parameters.
Check whether it needs dust/lint cleanout.
Check all fans for normal operation. (I had some system ram giving errors, because it was hotter than operating range spec, because the ram cooling fans were marginal.)
Check power supply voltages.

Thanks to everyone for help, I have most probably identified the issue - one of the four RAM modules was bad, the other three passed the memtest in a single stick configuration.

So far it's working...

A lot of RAM comes with a lifetime warranty. I'd look into it.
