[SOLVED] PC started having major issues after upgrading cooler ?

[torveo]

I recently upgraded my CPU cooler to a dark rock pro 4. I had some really weird issues after installing it. for example the system would just power cycle infinitely sometimes when i tried to turn it on. other times it would only power cycle 2 or 3 times and then I would get to the bios screen where I would have to manually choose a boot device.

I fixed all that stuff, I can get into windows now. However I run into some strange issues. The computer boots fine and appears to run fine. But after about 15 min of playing newer intensive games like Death Stranding directors cut, or up to 2 hours playing some older games like TF2 and some web browsing, strange things will start happening. The program im currently using will crash. if im browsing the web, i'll get "the page ran into an error" message. shortly after, other things crash like steam or discord. then explorer.exe starts having trouble and the task bar freezes or goes away. then to end it all off, windows blue screens. I've gotten a bunch of different messages on the blue screens, but the two I remember are "MEMORY_MANAGEMENT" and "kernel_security_check_failure". One time, it said it couldn't find the windows efi bootloader and that i would have to use installation media to recover the system, but that only happened one time.
None of this ever happened before I did the cooler upgrade. it was perfectly fine. I tried swapping back to the old cooler but it didn't change anything. Temps were great on the dark rock pro 4. my 4790k @ 4.7 GHz only reached 74c on the max heat prime95 stress test. and it idled at 25-30c.

My main question is, what could have went so wrong? I've swapped coolers plenty of times before and nothing like this ever happened.

My motherboard is an MSI Z97-G45.

Usually the case here is that the cooler block is too tight on the cpu and it kinda crashes the cpu on bending motherboard pins causing shorts etc. Try to re-install the cooler, not so tight this time

Edit: I saw you tried alreay swapping coolers. I 'd say you should have a look on the socket pins under the cpu

I actually forgot to mention that, it was late when I posted. Originally I did try backing off the screws on the DRP4 a bit, and I did try taking everything apart and inspecting the CPU and pins. Everything looked perfectly fine. I also tried reseating the RAM sticks and blowing the dust out of the slots, though there wasn't any. Checked all the plugs and wiring, removed the GPU and just used onboard, and even restored my BIOS to factory settings. Haven't run a memory test yet but I'll do that when I get a chance. I'm just so confused why it works for a while and then suddenly everything crumbles.

Since you are running at many different errors i would consider isolating parts to find the culprit. If you re sure the GPU is stable, i would first try another power supply and also make sure all contacts are ok. Kernel errors and memory management blue screens are quite common for a failing psu. All is left is your ram and your motherboard after that. You can try removing ram sticks and check if it's becoming stable and of course run a bootable memtest. Back off your cpu OC and see if it changes anything
