I believe with a Vaio you need to immediately start clicking the F2 key (at top of keyboard) as soon as your power up the computer. Keep clicking until you see a setup screen and that should let you access the BIOS. Changing the wrong thing in the BIOS can leave your Vaio useless. Use caution.
I also believe your Vaio should have something called Vaio Care installed (Start menu > Programs.) Within Vaio Care should be some diagnostic tools specifically designed by Sony for their Vaio product line. You should be able to check for specific Vaio updates, run diagnostics on hard drive, memory, etc.
