Hi

I noticed some strange blue sparkly artifacts on my desktop yesterday, so I installed the latest drivers but the problem didnt go away. As I was googling for solutions all the artifacts magically disappeared. However this morning, the artifacts came back.

I reseated the gfx card, blew all the dust away and connected the card with a different power supply cable. I still get vertical blue lines during start-up and once I get into Windows everything has a yellow tint with blue sparkles in darker areas. I lowered the res from 1680x1050 to 1024x768 and that seems to work but I cant work with this res.

I had overclocked the card from 513/1600 to about 580/1800 with some shaders oc as well.

Also, the signal cuts out every second on the native res. Could this mean that it is just a faulty cable? I'd try with a replacement DVI-cable but I dont have one.

Any ideas?


ps. My brother got a new pc yesterday which is 2 rooms down the hall but I guess some sort of magnetic interference is too farfetched...

pps. After 30 mins I came back to the pc to find that the artifacts are once again gone. What the eff?
 
lower the oc and see if it still artifacts, not all cards oc the same.
 
Do you have Vista? There were a few updates that put the hurtin on nVidia cards recently. My 7900 GTS I just replaced with a 9800GTX was artifacting pretty bad for a bit too (of course, the shit tons of dust on it didn't help) and I found out some updates did the same kinda things to several others.
 
Nope. I'm on a 32-bit XP. The artifacting seems to occur right after start-up and then end after the pc has "warmed up".
 
Weird, I had a very similar thing happen a few days ago to my 8800 Ultra but not quite. I turned on my system out of no where and all of post was garbled. All the writing was in ascii, different shapes, lines etc. As soon as Windows loaded however it was all crystal clear. I ran atitool artifact scanner for 2.5h immediately after Windows loaded without a single issue. I never did have another problem but that was by far the strangest post I ever had and I definitely wasn't on drugs. The artifacts it was producing was reminiscent of bad video memory but for the life of me I cannot replicate the issue. Not that I want to.
