A few months ago, I fried my CPU with a bad OC. About two months ago, I bought a brand new i7-7700k. It worked perfectly for about two weeks when it suddenly started acting up. Whenever I try to play a game, I either get a hard crash or a bluescreen (the ones that have been mentioned above and UNEXPECTED_KERNEL_MODE_TRAP, SYSTEM_SERVICE_EXCEPTION and KMODE_EXCEPTION_UNHANDLED). My previous CPU was an i7-6700k. I decided to buy a 7700k because it was slightly cheaper and my BIOS was already fully updated. The bluescreen first appeared while I was playing GTA V. I didn't think much of it and started my PC again. The next day, it crashed twice, and it just got worse and worse. Now all games either hard crash (they take a few minutes) or bluescreen.

I have tried everything to fix my PC, I:
Changed my RAM (Kingston HyperX 2133 MHz to Corsair Vengeance LPX 2400 MHz)
Changed my motherboard (Asus Z170-A to Asus Z270-F)
Removed my GPU
Switched CPU cooler
Removed Wireless Adapter
Clean install of Windows (it sometimes bluescreens while installing too)
Installed new drivers.
Alternated between my two HDDs while installing Windows
Ran SFC /scannow
Ran chkdsk
Still same problems.

I sent the PC to a repair store and the guy told me that the CPU isn't compatible because it's "too powerful" and that the new motherboard wasn't compatible with the RAM...even though both modules were DDR4 AND I was getting the same errors.

Any help?

Changing hardware on same windows installation is a headache. But you did mention a clean reinstall of windows.
I don't see why your mobo needed changing exactly.
Your memory (new one) is listed on your mobo's memory compatibility list:
http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/STRIX_Z270F_GAMING/STRIX-Z270F-GAMING_memory_QVL.pdf
but it's also listed on the old one:
http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/Z170-PRO/4L-memory_QVL.pdf
though admittedly only the c14 version is listed (http://www.corsair.com/en-us/vengeance-lpx-16gb-2x8gb-ddr4-dram-2400mhz-c14-memory-kit-black-cmk16gx4m2a2400c14) and not the c16 one (http://www.corsair.com/en-us/vengeance-lpx-16gb-2x8gb-ddr4-dram-2400mhz-c16-memory-kit-black-cmk16gx4m2a2400c16).

and the old one mentions in spec it supports 7th gen cpus:
https://www.asus.com/Motherboards/Z170-A/specifications/

That's all a moot point though. My recommendation is to first install latest bios for your motherboard (carefully follow asus instructions in order not to brick your board). You can find them here:
https://www.asus.com/us/Motherboards/ROG-STRIX-Z270F-GAMING/HelpDesk_Download/
I'm going to assume you also installed all the relevant drivers (chipset, lan, audio etc.)

Second, are you overclocking? If you are, bring them back to default temporarily until you can figure out what's causing the instability.

Then if bsod happens again, go to event viewer in windows and check for events that say critical around the timestamp of the bsod (within a few minutes). If it creates a dmp file, note its location and then post it to a file sharing site and link here so we can take a closer look.

Since you replaced the CPU and that worked for a while but then died again, I'd say that your fried CPU damaged the motherboard and the damaged motherboard damaged your new CPU. Before you try a different CPU, you could try disabling deep sleep states to see if it might be a power-related issue. You may also want to run memtest86 for 8+ hours and see if there my be a memory-related issue. If neither help, try getting a Pentium G4560 or other cheap CPU to put on your board and see if the problems go away.

I doubt that the fried CPU damaged my motherboard (and so on), mainly because I was getting completely different issues after replacing my CPU. With my old CPU, I was getting errors like CLOCK_WATCHDOG_TIMEOUT, while now I'm getting the ones I mentioned. Unless that doesn't really matter, then sorry for being silly. THOUGH, you're most likely right, since the guy I took my PC too said he put a new CPU on and it was fine.

Also, no, I am not overclocking. The new motherboard was on default and so was the old one when I got my new CPU.

You are extremely unlikely to see two CPUs have exactly the same internal failures from being exposed to the same bad motherboards because the weakest transistors within the CPU that will fail from whatever the bad motherboard will vary depending on the usual fabrication process variations.

I mean, the first CPU wasn't killed directly by my motherboard, but I do get what you're saying. I am in the process of RMA-ing my CPU. I'll buy a new motherboard too.
