[SOLVED] PC Freezes After CPU Upgrade

Hello all,

I just upgraded my CPU, mobo, and memory. When I boot up now, everything freezes about 5 minutes after Windows loads. Unfortunately since I upgraded 3 things at once, it's hard to find the culprit. It's a classic case of whodunnit!!!

Here is my current rig with the upgrades:

Intel - Core i7-9700K 3.6 GHz 8-Core Processor
Cooler Master - Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
MSI - Z390-A PRO ATX LGA1151 Motherboard
Corsair - Vengeance LPX 16 GB (2 x 8 GB) DDR4-3000 Memory
MSI - GeForce GTX 1070 8 GB Video Card
Corsair - CX (2017) 650 W 80+ Bronze Certified ATX Power Supply

I've done some troubleshooting already according to searching previous threads. Here's a list of everything I've tried so far:

- Tried different memory sticks 1 at a time in all different DIMM slots
- Tried using a different power supply
- Tried using different power outlets
- Rechecked all power and data connections inside the PC
- Temps are at 30 Celsius
- Reinstalled Windows
- Removed video card and ran graphics from mobo
- Set memory to native 3000 MHz in BIOS
- The freezing does not occur in safe mode
- Ran Memtest86 and received 3 errors. 2 in test 7 and 1 in test 8. i took pictures of the results, but I can't link the picture in this thread for some reason.

So the only lead I have right now is the memtest errors.

Does anyone have further suggestions or is it time to return these items?

Thank you all so much!!!
 
Solution
I went to Best Buy to try another processor.

Installed it, booted up, and let the pc run for an hour.

IT WAS THE CPU THE WHOLE TIME!!!!!

I CANT BELIEVE IT!! INTEL WILL HEAR ABOUT THIS!!

I want to sincerely thank everyone that has helped me through this process.

A few small problems on a new build keep things interesting. But this was so scary. Thanks again to the Toms Hardware community.

I believe XMP was disabled by default, but I will check when I get home from work. The memory defaulted to 2133 MHz when I ran it the first few times then I manually changed to 3000 MHz to see if it helped. I will also confirm this when I get home. Thanks for your response.

It looks like the XMP was disabled all along. I’m running memtest now at 2133 MHz and already have 2 errors after only 10 minutes of running it.

Does this seem to most likely be a RAM issue? Any chance to rule out the new CPU and mobo? Or is it too early to tell?

I just bought a different mobo and installed it. Unfortunately, my pc froze again. I absolutely cannot believe it!! The only thing left I have not checked is the CPU. Can anyone think of something else I haven’t checked yet?

Here’s what memtest is currently showing. Could this mean the cpu is bad?
