5770 sudden decrease in performance

[Willus Killus]

Been running a 5770 for around a year and a half now, and as of yesterday I experienced a sudden drop in performance.

Was running Medal of Honor at pretty high graphics without any frame rate issues, next day it is only just playable on low settings, also experienced terrible performance with Portal 2.

Also noticing some artifacts such as the one this fellow kindly demonstrates (middle of picture, glowing character).

I have done a full re-install of windows and the problem still exists.

Was wondering if anyone had experienced anything similar or if anyone might have any clues? I suspect the card is just worn or has damaged itself somehow.

The card idles at 34°C and I've never seen my temps go over 60°C so I don't think its a heat issue, I usually pay attention to that sort of thing too, since it was the death of my last card

The way it worked fine one day, and then when I booted up the PC the next day, the issues began makes me suspect more than just overheating.

I have also already tried a full re-install of Windows and the drivers.

I thought my PCI-E speed was supposed to by x16, however it seems to be displaying as x1?

Also shows up the same in GPU-Z

have you got 2 pci-e slots ? can try in the other slot ?

Nope, just the one.

Solved the problem

Took card out, booted system, shut down system, put card back in.

Seems to have reset something so the card is now using x16. Could just not have been seated properly I suppose.

anyways, thanks for the help gents.
