The other day I started getting this colourful display when loading my current game of choice.
Since it first started, it is now happening when loading into Windows. The screen is somewhat pixelated with pink or orange marks all over the screen.
I have tried various different drivers, and have installed them all cleanly, by removing the old ones, running driver sweeper, booting into safe mode, running driver sweeper again to be on the safe side, then booting into Windows normally, and installing a different driver.
I've also tried reinstalling DirectX.
Nothing has had any effect.
My machine doesn't run at all hot.
The graphics card is a 8800GTX, purchased when they first came out, so it's probably time for an upgrade anyway, but I wondered if anyone had any suggestions as to what may have caused this? Case is pretty dust free, no hardware/software chages recently either.
Also, on the topic of graphics cards, I didn't build this system myself. The graphics card is running off of the normal 2 power cables, but along the side of the graphics card there is also a thin black cable, with a metal end, which has been taped onto a small metal plate on the side of the card. Anyone have any idea what this is?
