What is the name of the children television series?

I ask this just for the nostalgia. It was American children's television series. I donno it was shown in television or not because I bought CDs but I lost those CDs many years ago. It was about 13 years ago. The show is like Ultraman, but the hero is a teenage kid. He fights those 'godzilla' in cyberspace. When he wants to transform to 'ultraman', he will randomly type on his laptop, and he goes inside the laptop/virtual world. The setting is usually inside a high school. Anyone knows it?

Could this be it?

V.R. Troopers (1994-96 TV series)

IMDb synopsis:

Carl Ziktor's virtual alter-ego Grimlord worked on the creation of an army made of warrior robots. And, before he became missing for two years, Ryan Steel's father worked with Professor Hart to prevent Grimlord's efforts by developing the ultimate weapon using the most advanced technology man had ever seen to stop him. Now, with the help of his friends J.B. and Kaitlin, Ryan and his friends use the VR power to prevent Grimlord's army from crossing over into our reality from Virtual Reality--and ruling it. However, will Ryan ever find his father?

I think that YouTube has a number of episodes:

I seem to recall another PC-connected TV series that aired in the afternoon. I wonder if I can track down that one. If "V.R. Troopers" isn't your series, perhaps the other one is. // EDIT: The next poster named another possibility, but it's not the one I was thinking of. So, now there's a THIRD series I have to find!

Was it Superhuman Samurai Syber Squad?
