Hey, for the past few months i've been having an issue where the majority of downloads corrupt if they are downloaded from a browser, it doesn't matter which browser, however monitored downloading software such as steam or torrents seem to work fine, though nvidia graphics drivers do not. Thinking the issue may have been corrupt system files or malware I went through many methods and yet none of them worked, this lead me to doing a fresh install of windows (8.1 pro), though this has not solved the problem at all and I now im finding more problems with corrupt downloads (steam can't update, java wont install). I have also ran a memory diagnostic and there seems to be no issue there, what could it be?
