PC crashes on high GPU load

Hello, I'm new on these forums, I'm hoping I can get some help in regards to my PC.
My PC started having problems since I upgraded my GPU to a Sapphire RX 460 2GB OC DDR5. When I try playing games, or sometimes even watching a high res video on youtube the computer will freeze completely (sometimes the screen goes black for a sec, crashes the game/video and will come back, but it will do this 2-3 times before freezing completely) and I have to reboot it or turn it off via power switch. It happens depending on how graphically intensive the task is, say I'm playing EVE Online, game runs fine for 15 to 20 minutes before crashing, happens in Rust after 40-60 minutes, Mortal Kombat X crashes almost immediately (20-30 seconds), but lesser graphically demanding older titles like DMC3SE, CS:GO and Osu! don't crash at all. I've resorted to underclocking my GPU as low as it can go on Radeon Settings WattMan, and while it does lower FPS by a bit, I can play for a few minutes longer before crashing.
These are my specs:

Sentey Metal Blade Power - 750w Modular 80+ Bronze
AMD FX 8350 Black Edition
Sapphire RX 460 2GDR5 OC
8GB of DDR3 Kingston RAM (detail on RAM further down in the post)
Motherboard ASROCK N68-VS3 FX
HDD Samsung HD250HJ 250GB

I've tried a number of things before posting here, such as re-installing the drivers after a fresh DDU driver uninstall, fresh OS installation of W10, different PSU (before this Sentey power supply I had a Thermaltake TR2 500w, which I thought might not supply enough power to my PC), reseating my GPU in case of bad contact, dusted off every component, clearing CMOS, reconnecting HDD cables, updating BIOS to most current one. None of the above worked.
Detail on my RAM, I'm currently using 2 4GB sticks of Kingston ddr3 RAM, one is dual channel and the second one is single channel, I thought this was causing the problem so I borrowed 2 sticks of DDR3 HyperX Fury reds from a friend, but the problem persisted.

Things I'm considering might fix the problem are: Upgrading the motherboard to a newer one, putting new thermal compound on CPU (I don't have any on the CPU right now since I *cleaned* it off a month ago [I don't have any IPA so I don't know if that counts as cleaning it off]), trying the card on a different system to see if that's what causing the problem and upgrading the HDD.

Thank you guys in advance, I hope I can get this fixed soon!

I'm actually surprised you're not having more problems; neither FX CPUs nor 125W CPUs are officially supported by this motherboard.

How low-end was the previous GPU? It's possible that, if it was very low-end, you simply weren't taxing the CPU much.

At the very least, you should *not* be running the CPU without thermal paste.

Well since you said that you removed the thermal paste, I would start there. I would think that your cpu is cooking itself under load. Do you have any idea what your core temperature is?

Hello, thanks for your response, I think I've found the solution, and it might have been a problem with Plug and Play.
I've ran MKX for a bit now, my CPU temps are 29C when in desktop and 68C in game, GPU's temps are 19C min / 35C max, I don't know how accurate these reads might be since ASROCK sensors are not the best in the game, but I hope they are at least approximate.

I've read in another thread someone had a similar problem where they would get BSOD when running high res videos and playing games, and someone suggested reinstalling some drivers that might be causing problems with windows Plug and Play, so I reinstalled my Wireless LAN driver and my VIA HD Audio driver and I was able to play MKX without crashing, I have not tried yet other applications or running my card at stock clocks, so I'll leave this thread open until I'm sure the problem is solved

UPDATE: Rebooted and tried running GPU on stock clocks, problem persisted, computer froze 20 seconds into MKX

Hello! Thanks for the response, the original components on this motherboard were an Athlon x2 64 Processor and ASUS R7 250X, which also crashed from time to time, but even with this card I'm not taxing the CPU that much. To be totally honest I had no idea this motherboard did not support FX CPUs, I'm sure that's the main issue right there, I'll buy some thermal paste today and try the GPU on my friend's system to see if the card runs properly. And I'll be buying a MSI 970 Gaming motherboard soon enough.
