Hi, this evening I was using my computer and suddenly columns of green lines start appearing on my screen. I tried restarting the computer and then got some purple lines. I hooked my comp up to another monitor and got the same thing. Downloaded new display driver and installed it and no avail. My LCD then starts telling me that I'm in an unsupported mode, and then goes blank, not giving me an image. I was pretty sure it was a video card problem, so I bought a new one, installed it. The lines are gone now, but sometimes there are two or three pinkish lines which follow my mouse cursor around. If I run a 3D game the rendering is completely messed up. Since I already tried a new card I don't know where to go from here.

Thanks for any help.
 
Well, if the new card fixed the problem somewhat then your old problem was most likely with the old video card. Your new problem however (if your new card is better than the old one) is most likely your power supply not being suffecient for your system...thats my 2 cents hope it helps you out.
 
Thanks for the replies. It's kind of odd though. 2D games such as Baldur's gate run perfectly fine, but any 3D rendering causes massive display problems.

- If something is wrong with the motherboard, what and how can I check it?
- Similarly, how would I know if my power supply isn't enough?
- I'll try uninstalling a few codec packs I have downloaded and see it it helps.

Another thing that occurs is that when I start my computer, the Dell loading screen that comes up before the windows loading screen the colors are completely messed up. When it hits the windows loading screen the colors are back to normal. :confused:

I just bought a ati x1600 agp if that clarifies anything.
 
The ati card recommends a psu of 350W and above. The one I currently have is 300W. Will this difference really cause these problems I am seeing?
 
"Your new problem however (if your new card is better than the old one) is most likely your power supply not being suffecient for your system" sometimes, yes. other times, no.you say it is a lcd screen? i'm not sure,maybe if you took the screen out of it's native resolution?

I just tried an Antec 500 W power supply. No luck. One thing I noticed is that when I disable the mouse pointer accleration in the display properties, the faint lines on my mouse cursor go away. This makes me think it may be a software problem? I have the newest ati and directx drivers installed. Anything I' m missing?

My bios are 3 years old will that affect anything?

Thanks in advance.
