Can someone help me?

iMac late 2015 27"
Processor: 3.2GHz Quad-Core i5
Memory: 16GB 1867 MHz DDR3
Graphics: AMD Radeon R9 M380 2GB

I installed new a SSD & 2 new RAM sticks.

Is it the CPU I need to change out or the 7200RPM hard drive?

panic(cpu 3 caller 0xffffff80125f06a9): "Double fault at 0xffffff80126034fa, registers:\n" "CR0: 0x000000008001003b, CR2: 0x00000000bd4dbee8, CR3: 0x00000000165ae000, CR4: 0x00000000003626e0\n" "RAX: 0x0000000000000000, RBX: 0x0000000000000002, RCX: 0x0000000000000001, RDX: 0x0000000000000000\n" "RSP: 0x00000000bd4dbef8, RBP: 0xffffffb0bd4dbf20, RSI: 0xffffff80133dce80, RDI: 0xffffff8013250760\n" "R8: 0x0000000000000001, R9: 0x0000000000000004, R10: 0x0000000000000000, R11: 0x0000000000000001\n" "R12: 0x0000000000000010, R13: 0x0000000000012070, R14: 0x0000000000000000, R15: 0x00000000ffffffff\n" "RFL: 0x0000000000010002, RIP: 0xffffff80126034fa, CS: 0x0000000000000008, SS: 0x0000000000000010\n" "Error code: 0x0000000000000000\n"@/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/xnu/xnu-7195.50.7/osfmk/i386/trap_native.c:168

I am happy to get on this forum with folks who know more than I do! I am a newb, but I'm open to learning. I would love it if someone could lend me a hand with this challenge.

I keep having kernel panics.

I am having a similar issue as jesseonate on the same model with a 32 GB Ram - it's a refurb. I believe that both the RAM and the 1 TB SSD have been upgraded. Here is mine:

panic(cpu 1 caller 0xffffff8021b6ea25): userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds

First things first: boot the Mac from an internal drive with a fresh install of the os on it. If you don’t get a kernel panic - then you know it’s just something buggy in the os on your internal drive and you’ll be best off wiping that drive and re-installing the os and all your apps and files manually (don’t use a backup since that would likely bring over whatever voodoo is causing the panic)
