PC randomly has black screen of death(?)

[84376_1454179861]

Hello, I've been living with an issue (for a long time now) where my screen will at the most random times turn black first, then after about 10 seconds the audio cuts off, ultimately resulting in me having to restart my PC.

 

This happens mostly when watching a video or idling, it's only ever happened once when playing a very light weight game, may just be coincidence but it seems to ONLY happen when it's not doing hard tasks. And it's extremely random when it happens, sometimes it doesn't happen for months, and very rarely it can happen 6 times a day.. sometimes once a week, sometimes 1 a day for a few weeks, absolutely random.

 

I had this issue since BEFORE I've upgraded my PC, I've changed my PSU, changed my mobo, my CPU, and my GPU. I've had 2 GTX 660s, an old AMD GPU (forget the name) and this 290x, persisted from windows 7, going to windows 8, and still here at windows 10. this random black screen has persisted through all of the changes, the only thing never changed is my Harddrive. I've also done a factory restore but the issue has persisted. Could it be my harddrive? Or is there perhaps a commonly ignored software that causes this I might have? Would like to know before I try buying a harddrive and moving everything over..

 

Specs;

Windows 10

R9 290x Sapphire

Because of the crashing I'm an extremely paranoid person and always watch temps, highest my GPU's gone is 60C, highest CPU's gone is 40.

 

My antivirus use the be Avast until it started causing other unrelated issues, I've uninstalled that about a month a go and have been using plain old Windows defender.. and also Malwarebytes.

Have done it a couple of times already, unless there's some extra steps I've never heard of..

Sorry, yes, I have, I forgot about that. My bad.
