Right, I have an image finally of it doing it.
I had the CD drive open, and my brother closed it. It happened straight away.
The more you move the mouse around, move folders about, scroll up down an internet page, the worse the image gets, until you place a new window/web page above it. Then as you move that, that gradually gets worse too, until its covered in green, and JPEG type mess ups, until text etc becomes very unreadable:
its not just limited to programs though, it happens on everything!
So weird I know, but thats after moving it about a bit. It started out with just dots...
I just did a reseat, but I probably won't know for a while.
What got me concerned though, was how it occured after a DVD drive was closed.
Closer inspection while connecting power cable back up, was that I wasn't giving the graphics card its own 12volt connection, and its infact sharing it with the hard drive and the DVD Rom drive.
I can't do anything about that since this PSU don't seem to contain that many connections
Could this in fact be the course?
