Hi,Paul.
I'm John.I have a VAIO PCV-RS222.And I've got exactly the same problem as you got with the bleeping and flashing.I still haven't found the answer yet of what's the cause of it.But I think it's got something to do with overheating.The last few days my computer keeps bleeping and flashing.The last few days it's also pretty hot weather and very hot in my living room also.
And when I'm using a lot of CPU performance it also will flash and bleep.But I just think that's the problem , I'm not sure.
Hopefully you know what's the cause of this problem.
Good luck and greetings.Same VAIO RS222 problem.
