Monitor, audio devices and internet keeps disconnecting and reconnecting repeatedly, suspect it might be related to HDD

So I was downloading GTA:V onto my 1TB hard drive, it had about 150GB left on it and GTA is about 70GB. When I started the download, immediately my monitor, audio devices and internet disconnect and reconnect about 10 seconds later, this happened quite a number of times in 10 minutes. As soon as I stopped the download and uninstalled the files, the issue fixed itself. Could this be a problem with my hard drive and if so how could I fix it? Is it a storage space problem?
