[SOLVED] New Build: laggy and BSOD in Windows 7, can't even install Windows 10

I installed a new motherboard (b450-a pro), CPU (ryzen 5 2600), ram (16 gig gskill) and GPU (1070 ti) but kept my old SSD.

Windows 7 installs successfully from CD but is VERY laggy and blue screens within 5 minutes . I can't even install the motherboard drivers from the disk that came with it because it blue screens before it can install. It even blue screened towards the end of the windows 7 installation.

BIOS runs fine with no lag (in W7 the mouse inputs could lag for 30 seconds before registering).



Okay so maybe its compatibility issues with W7 and my new hardware - so let's try Windows 10!?!



Got windows 10 boot media and am getting the following error when it gets a couple percentage points into the installation step "Getting files ready for installation":

"Windows cannot install required files. The file does not exist. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070002"

I have tried both bootable USB and DVD methods for installing win 10 and get the same error. I made these from the official windows media creation tool from Windows website and they were two separate downloads - unlikely that its a bad ISO?

The W10 installation also feels quite laggy.

Ran 9 passes (21 hours) of memtest with no errors. Any way to troubleshoot other hardware issues?

Can't get drivers without going into the OS and it bluescreens in windows 7 and can't install windows 10.

Any ideas? Its the worst not being able to use my new PC 🙁
 
Solution
What are the bsod errors? Stop code?
Had very similar issue myself, system was overall very buggy, slow and unreliable.
Ran memtest, 10 passes.
I still suspected the ram because of the stop codes were all memory related.
Replaced ram, and it's working perfect.
Memtest86 isn't as reliable as you may think.
