Windows 7: Trouble installing Windows 7, Z170 Chipset

Trouble installing Windows 7, Z170 Chipset

Hi everyone. Just joined, seems like a great community . I'm having serious trouble doing a clean W7 install, and it's driving me nuts! I just upgraded my PC with a i7-6700K Skylake CPU, MSI Z170-A Pro MB, and Corsair Vengeance LPX DDR4 2133MHz 2x8GB RAM. At first I just plugged in my SSD with previously installed Windows 7 x64, and actually got it working (after enabling AHCI in registry, getting the right USB/Ethernet drivers with another HDD etc.). It seemed to work just fine for a day or two, before it suddenly froze. When I tried booting it froze within 30 sec on boot. I played around in safe mode trying to find what caused the freezes, before finally giving up and deciding on doing a clean install.

I became aware of the whole USB3/EHCI/xHCI issue, and are therefore installing from DVD with a brand new DVD reader (SATA), and PS/2 keyboard. The trouble is, it's freezing right before I come to the point where I choose HDD/SSD to install on. I've tried beginning the installation in another PC (same DVD reader/disc), and moving the SSD when it's rebooting, but with no luck. I've enabled "Windows 7 Installation" in BIOS, and also tried disabling USB altogether. If I leave it for a while I sometimes get a BSOD with message "MACHINE_CHECK_EXCEPTION". What could be wrong? I know this installation method should work..

Update: I get the same "MACHINE_CHECK_EXCEPTION" during Windows 10 install. Memtest86+ finds nothing wrong.
