About a week ago my computer started to slow down and I noticed that my HDD disk usage was at 100%. I tried to restart my PC and it wouldn't get past the bios flash screen. I was able to reinstall my OS and my computer was working fine again. Now however I am having the same problem. Startup repair won't work neither will ,sfc/scannow, windows refresh, startup repair,or rebuild BCD. Now I have error code 0xc00000e9. Could it be my hardrive needs to be replaced?
