Welcome back Gary, I have a 12 year old pc myself with 12 GB Ram and biab 22 seems to run fine on it.
I haven't read the whole thread, so sorry if it was mentioned before,
1 Exclude the bb folder from any anti-virus scan.
2 disable as many windows startup programs as possible in Task manager.
3 Try either rolling back the video driver or updating it, think that download installs a sound driver as well.
4 Try Asio4all and mess around with settings buffer size etc.
Hope you get it working asap Gary, good to see you.
