Lines in the graphics

Howdy

My cousin gave me his comp to fix, well his antique, lol. It is a pII 300 mhz, I have reformatted it, and installed aida, but I can't find out the name of the motherboard, I will have to open it later, the graphics card is a 3dx voodoo or something like that, anyway there are these vertical blue lines, and during boot up the lines show up as vertical dotted lines, my guess is the graphics card is kaput. My question, does the blue vertical lines ring a bell for anyone?


cheers
