This past week I have been trying to reformat my computer, however every time I try to install windows, I receive errors messages. My friend helped me run a diagnostic program on my computer and all the tests were ok except my file structure test, it failed with many errors. I formatted and checked my hard drive to see if anything was wrong but nothing. The test fails with critical errors after I format my hard drive into NTFS. I've never had this problem before. I did just install a new motherboard** but I dont think that is the problem because it passed the diagnostic test. Please help!
