Weird artifacts on Vista login screen with CPU OC

post #1 of 4
Thread Starter 
I'm getting some strange artifacts or something when I load into the Windows Vista screen where I put in my password. It only happens when I fiddle with my settings in BIOS. Right now I am trying to overclock to 3.6GHz. No matter what speed, though, I get these weird artifacts. I don't have a picture or anything.

Part of my screen turns black and I can see the rest of it normally. The ends of the black part are all jagged. It sometimes takes up 1/2-3/4 of the screen or sometimes takes up 1/4 of the screen. What is causing this?

I'm running 1800FSB x8 multi (3.6GHz) and my memory is underclocked at 900Mz. I'm running Prime95 right now.

Happens to me too, but even when I'm not overclocked. The thing with mine though is that it's only there for a short period of time and then it goes away when I actually log in.

Does your screen stay like that after you log in too?

No it only happens for a brief second then when the screen finally loads it goes away.

Mine does this too. It's only on the log in screen and whenever I hit ctrl+alt+del I can see them too. I switched my gpu once before and went away but the card was no good and I had to switch back to my 7600gs agp card. I'm hoping with my new setup it will go away.
