Frustrated

I’m so frustrated. I don’t know what’s wrong but my site’s working well on my current computer ( win xp, pentium 4 3.2 E HT, 1 gb ram ) but it ain’t working well on my old around 5-yr-old computer ( win 98, 750 MHZ, 20 gb hdd, 64 mb ram ). When I run the site on my old computer, the gradients run off, the text is blurred, it looks bad. What could be the possible reason. I’ll probably test run on a laptop pentium 4 tmr or so.
