If it continues to show up on a new installation there's likely three factors:
Unstable/failing RAM placing bit flips on your data as it writes to storage, corrupted.
Unstable/failing storage not being able to read or write data correctly to/from storage, corrupted.
Corrupted installation media placing invalid files on your system. This could be the image or the storage mechanism like flash drive.
I'd try writing a large file (larger than the Windows ISO) to the installation medium and then try reading it back to receive the same sha checksum. That will tell you that you can read/write to the installation medium reliably. Obtain a new Windows ISO and write it to the medium.
You can use utilities like Memtest86+ to test RAM for errors and SeaTools or another hard drive manufacturer to run scans on the drive. The UBCD contains a useful bundle of diagnostic utilities, or Hiren's Boot CD. It might also be worth resetting CMOS to defaults if there's any parameters pushing the system out of spec such as RAM frequency and timings.
