My desktop PC is a pretty tough one. For over 2 years I've been using this custom desktop (consisting of all types of parts, will post specs later)
It first started by using an application called Worldcraft which is a map-editor for Quake engine video games when I was active for a couple moments and dragged stuff around, when I was active either in the 3D view and dragged stuff around or my mouse cursor started freaking out in the interface and was ported into the top left corner of my screen. Sometimes I get extra graphic glitches and a second later my screen is black, my monitor receives no signal. this also happens when using Skype's webcam, sometime it happens when using Google Chrome or using VLC in DirectX mode - it is pretty much every program that makes use of of my GPU. It doesn't happen when not having my Nvidia drivers installed so it's most likely a GPU issue.
Another thing is, 2 years ago I still used Windows XP, last year I checked out the Windows 8 Consumer Build, then switched on a fresh install of Windows 7, then back to Windows 8 and then back to Windows 7 again - all in a time span of over 11 months. I started fresh every time, new drivers etc. so it must be hardware related. Surprisingly, I have no issues on Ubuntu 12 (using Nvidia's official proprietary driver).

I would like to hear your input on this, maybe you can tell me why it happens. I would like to be certain before acquiring new hardware.
