Hi Mark,

The video card idea is worth looking at, hadn't though of that. I bought the MB from a colleague who was into music creation. He wasn't bothered about the video card, and it might even be on-board video. It was over a year since I built this machine so I will check tonight. If it is on-board, or low spec, an upgrade would be worth a try.

I think this latency is the route of my problem, just a matter of finding out the cause. If it is AVG then that would be annoying since I would have to drop internet access on the garage machine, which is quite useful.

The processor was reasonably good, an Athlon XP 2600, and I put in a fair bit of ram. MB was a well known make.

I'll post back if I find out any more, thanks. Other suggestions welcome . . .
