Thank you! I've never come across one before and I just wanted to see if anyone could verify this too. It definitely feels rounded at the top compared to a few others too.
The computer this works to seems to operate other then if you put in a PCI-e gfx card, there will be a lot of artifacts on the screen and sometimes it crashes. Does this seem a feasible culprit.
Definitely if you read the symptoms section in the link i posted your gpu problem is referred to.
Unfortunately the whole system will suffer instability over time.
