everything seemed very nice, except the one fact - it lags very much when you scroll or move window.
You have hardware from the late 1990s. Specifically note the 400MHz CPU and the 512 MB of relatively slow memory. The graphics card supports DirectX 5.
You simply cannot install a modern distro on this hardware and expect it to perform well. Modern software is designed for modern hardware. A modern processor is about 20x more powerful than yours. A modern machine has about 12x the main memory than yours. And the graphics card, well, technology has undergone a near-complete fundamental transformation since that era.
Modern software makes assumptions about hardware specs that really don't apply to that old of a machine.
That hardware might work well with a Linux distro of similar age. Perhaps Debian versions Potato (circa 2000) or Woody (circa 2002) would run nicely on the machine.
