[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!!!

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?
 
Return the entire kit of memory for replacement under warranty. If you have not had the memory very long, you probably can return it to the retailer. Otherwise, tell Corsair the memory has given you errors and they will give you RMA information.

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?

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.
