I've used Windows 95b for so long, because it's very stable. Up to the point where USB support was needed (PC camera and so on) I figured the need to upgrade to Windows 98 SE. Most softwares were already installed and would take so much time to re-install them (because they were running fine after 98 was installed). However, a week or so after Windows 98 SE was installed, the computer came so slow that the video had to render the moving window for every 1/2 second when I moved them, and memory boggled down to crumbs. I'm not sure whether Windows 98 SE is to blame, and have no ways to figure out what is going on in the background. Is there any applications out there that I can download to observe the running processes that normally don't show up in task manager (like one in Windows NT) which allows me to better troubleshoot the problem. I am running Pentium 166 mmx (yeah, I couldn't afford newer one for a while) with 128 MB RAM and plenty of HD's with massive free space, so Windows 98 SE shouldn't be a problem. Any ideas or suggestions are greatly appreciated.
