I was hoping someone could help, I have recently in the past two days noticed a tremendous slow down in loading speeds on my games to the point where I simply had to close them because it was taking so long. I have cleared and optimised a lot on my HDD and it has no fragments on it, I then ran a performance monitor which told me that I had hundreds of thousands sometimes millions of cache errors and also I was having very high waiting times from my Hard drive. I was wondering if the high wait time was contributing to the cache errors, I conducted a standard RAM test and there was no hardware issues to be found therefore I was thinking it could be that my ancient HDD is dying? I read somewhere that the RAM tests are not 100% accurate and also read that the high wait times on disk also contributes to very high cache errors. My disk space at the moment is always at 100% when running windows if that helps.
