So I just installed the DeepCool Gammaxx 400 today and now my PC will not boot into Windows. Everything shows up fine on the BIOS of my mobo, but when I try to boot, the OS displays the 0xc000000f code saying, "A required device isn't connected or can't be accessed." Afterwards it then times out about a minute after input. I cannot access adv. system settings and I can't try again all it will let me do it open the UEFI. When I looked up the code, some places said that my boot files may have been corrupted. After attempting to fix it, after having to download Win10 onto a flashdrive, nothing changed. I tried to restore but I don't have any restore points, and I can run any repair systems.

Here are my specs:
Asrock B150M Pro4
I7 6700t @2.8GHz
Insignia 550w 80+ bronze
PNY Gt 1030 2gb
12 GB of generic Samsung ram
A 240GB Kingston SSD (with nothing on it)
DeepCool Gammax 400

Edit: My copy of windows is OEM. And I know that these types of the OS freak out after detecting a new piece of hardware

Edit: I have reverted to my old cooler with no avail.

The ONLY hardware that can affect your OS installation is the motherboard. That is the only component that is ever tied to the license or digital entitlement as that is what Windows SEES as the "computer".

I would double and triple check that you have not accidentally knocked free one of the SATA data or power cables from one of your storage drives. I would not be surprised if your power supply was a factor either. That's a pretty crappy model.

When you say "nothing on it" in regard to your SSD, what do you mean? Do you mean "nothing", or do you mean "no games or applications, only the operating system"?

Honestly, I'd probably double check EVERY connection, including that both the 8 pin and 24 pin motherboard cables are installed...

Honestly, I'd probably double check EVERY connection, including that both the 8 pin and 24 pin motherboard cables are installed and didn't get bumped loose.

If all else fails, you may need to bench test the unit in order to figure out what's going on.

So I found out, after lots of trial and error, with a lot more error than I'd like, that I had the boot order incorrect. Instead of having the system actually boot windows, it was booting other things first and stopping.

And when I said "nothing on it" about the SSD, I literally meant nothing, I had just unboxed it when I did the cooler.
 
So what you meant was "when you try to INSTALL the OS", not "when I try to boot", right? Anyhow, at least you got it sorted out. That's all that really matters. Good luck and hopefully no further problems. For the OS install, I would HIGHLY recommend following these procedures:

***Windows 10 Clean install tutorial


And that you take a look at these in case they may apply to your Windows license if you are transferring it to the new system.
