PC crashing after upgrading CPU

[EnderDyno]

I upgraded my cpu from an i3 4170 to a xeon e3 1270 v3 and my pc started crashing randomly. I ran cinebench r23 and it was fine, no crashes. The temps did reach around 90⁰C but I'm planning to replace the stock intel cooler anyways. I also launched a game for a few minutes and it ran fine, but when I closed it the pc crashed. Monitor loses signal, pc stays powered on, peripherals also are powered on but cant do anything with them so I have to hold down the power button to shut it off. Audio is also for some reason screwed up on both the headphones and monitor speakers. Theres crackling/popping/static noise when audio is being played.

Specs Before:
CPU: Intel i3-4170
Motherboard: Gigabyte H81M-S
RAM: 16GB
GPU: Sapphire Pulse RX550 2GB
PSU: 750W (doesnt have a brand name)

 

Specs After:
CPU: Intel Xeon E3-1270-V3
Motherboard: Gigabyte H81M-S
RAM: 16GB
GPU: Sapphire Pulse RX550 2GB
PSU: 750W (doesnt have a brand name)

 

Fixes I've Tried:
Clear CMOS
Reseat RAM (and every other component)
Update Windows
Reinstall Windows
Change TdrDelay value
Updating Chipset Drivers
Updating/Reinstalling GPU drivers

 

I haven't tried updating the bios.

I think it might be the PSU that's the problem but I'm not sure. Do you guys have any idea as to why this is happening and how to fix it? If the problem does end up being the PSU would a 600W 80+ Bronze (CoolerMaster or DeepCool) be good enough? Also planning to upgrade the GPU to an RX 5600XT or GTX 1070.

I just updated the BIOS and it's still crashing randomly.
