Video malfunctions on boot?

Weird? Very!

My work purchased an ASUS Geforce2 card for me about a year ago, not sure the exact model. It worked fine for a little while but then sometimes when I'd turn on the computer, I would be presented with very bright and vivid colors that would be either horizontal or vertical lines (sorta?). As the PC loaded, it'd change colors and patterns. After it loaded, I could apparently login to windows (just guessing by the sounds of hard drive and speakers), but the video was simply messed up!

This wouldn't happen "all the time" though, I could power cycle the thing and it'd work just fine.

We RMA'd the card and got a replacement about 6 months ago. However, it soon began to present the same problem (I seriously wonder if they tested it once and shipped the same card back). I tried reseating the card, I put another card in the system to see if it would still happen... it didn't. I tried everything I could think of.

It finally got the point where it was unusable almost. So I brought in my Geforce4 and took the Geforce2 home. I haven't had the problem with my work machine anymore, and now I have the problem at home, which leads me to feel it's for sure the video card alone and nothing with the computer it's in.

Any ideas on what this is a symptom of? Can it be resolved? If not, I'm pissed at ASUS for sending me two crappy cards :( Thanks for your time.

Sounds like a RAMDAC or monitor problem. Asus could very well have just shipped you back the same card.

The RAMDAC is what converts the pixel info from the GPU (digital) to the signal that actually goes out to your monitor (analog.) Funky colors and vertical and horizontal lines are classic RAMDAC malfunction symptoms.

If your monitor is good, then my bet is on the RAMDAC on the card.

Ohh, to answer your question about if it can be fixed or not.


No, not without more expense than it is to buy a new card ;)

Yeah, it's probably the RAMDAC then since I've had it occur on 2 Gateway (Sony I believe) monitors, and my Samsung 955DF, all three work fine with other cards...

Thanks for the info though, I'll have to see if we can still get a replacement under warranty, thanks!
