I've had this computer for only a couple days and this is a really annoying problem to have already. 99% of the files i am trying to download through either chrome, Firefox, or IE don't happen. They all stop downloading at some point during the download and just stay at whatever percent they were already at. I booted into safe-mode with networking and tried the downloads there and they worked fine. I ran Malwarebytes Anti-Malware and it didn't show anything. I then ran a boot time scan with AVAST and that showed me a bunch of corrupt files (all the failed downloads from the couple days I've used it) but nothing wrong otherwise. I've tried uninstalling and re-installing both the wireless and wired drivers but the problem persists on both. Does anyone have any ideas?

Also while using steam to download games it would download around 200 Kb/s when on my previous computers they all downloaded the same games at around 1 Mb/s and they were of much lower quality then this one. I assume its due to the same issue of the internet constantly being "interrupted".
