Yeah, 1Gb of RAM is barely enough for Windows 7 itself to run in, let alone any applications. This forces Windows to constantly bang on the Page File, which is located on the very slow (compared to RAM) hard drive. This could very well be your problem.
My minimum recommendations for Windows 7 is 3Gb for triple channel motherboards and 4Gb for dual and single channel. Your's is most likely dual or single. But note even 1 more Gb will be a big improvement. Here is my canned text on RAM wizards:
These popular RAM makers have auto-scanning and/or manual entry RAM wizards to help you determine which RAM is compatible with your motherboard. For manual entry, enter/select the PC or motherboard make and model number and the wizard will list compatible RAM.Crucial - Memory AdvisorThe following retailers have auto-scanners and manual wizards. They sell brand name and/or "house" brand (re-branded) RAM.

You also need to make sure you installed Windows 7 drivers for all your hardware, including your sound device. Since this is old hardware, Windows 7 drivers may not even be available. In that case, you can often use Vista drivers.
If you go to the control panel under Troubleshooting, there are two troubleshooters you might try. One is "Troubleshoot Audio Playback" and the other is "Check for Performance Issues". Maybe one of them would lead you to a better solution.
