I have a Pentium MMX 200Mhz system, dualbooting Windows 98SE and Windows 2000. Some days ago (because I rarely played DOS games and only played early Windows games which runs smoothly in Windows 2000) I decided to remove Windows 98 and fresh-installed Windows 2000.

You might as well dispense with such old hardware entirely. Anything that runs smoothly in Windows 2000 can probably be run easily on a much faster computer than a P200.

I don't know why, but this newly-installed Windows 2000 tends to freeze often while I was playing game or browsing.

What should I do to resolve this issue?

Who knows? What else did you install? What other hardware do you have? Do you have the latest drivers for everything? Did you install Service Pack 3 and the other updates since then?

One more question: This PC has Yamaha OPL3 ISA sound card. Is it good?

Do you not like the way it sounds?

While this is obviously true, the whole point of this forum is for people to discuss using older computers 😜

MB, what -exactly- are your symptons?
Have you installed everything needed and in the correct order?

Check the fans and maybe run memtest86.

And check the event log.

I opened up the case and cleaned everything, reseated all the cards, and it seems that the soundcard slot was not tighten up properly. (I inherited this machine a few months ago, and never opened it up)

I reinstalled Windows 98 on it, and it runs quickly than ever.

Thank you very much.

@Jorpho: The soundcard sound was not clear (or somehow distorted) maybe because the slot was not really tighten. Since I reseated the slot, it is even better than my onboard Realtek on my Pentium 4 😁

Thank you very much for all your help here. 😀
