You need to tell us what CPU is in your system. Looking up the spec on the dc5100 shows it came with either a socket 775 Celeron or Pentium P4. Most of these were single core 64bit CPUs. Check yours and if it is 64bit, then install one of the 64bit Puppys and you will have a selection of modern browsers. Would suggest you try Firefox or one of it's derivatives since they require fewer resources.
