Regression : ReactOS setup BSODs on HP prebuilt

I have a base model HP Compaq 6000 Pro microtower (Intel Core2 Duo E8400@3.00GHz, Intel Q43 Express chipset, Nvidia GeForce 210), on which I decided to try ReactOS. The version 0.4.14 installs and works with no problem (except the drivers, but that's kind of expected), but version 0.4.15 and build 2e85425 both end up with a STOP 0x00000139 (KERNEL_SECURITY_CHECK_FAILED) when starting up both LiveCD and BootCD.

I don't have another PC with a serial port, so I can't provide more debugging than a photo of the BSOD.

I did get the LiveCD working though for some reason, after having enabled file logging, but the same exact fix only resulted in a black screen for the BootCD, and since it is loaded in a RAM disk, I can't get the file with the debug info.
