I can't get to anything. Only the acer
empowering people intel logo on the sreen and a menu task bar at the bottom that says press<F2> to enter setup, <f12> to enter Multiboot selection. That happens if I press the f keys repeatingly while start up. Samething if I press alt f10. I removed batteries Ram and replaced. I can hear fan and DVD drive if I place a disk in. I did not recieve a boot disk. the OS is Vista Home Premium. The laptop is the ACER ASPIRE 6920 and it was purchased on 8/08. It was in for repairs and they installed Norton Antivirus. It was acting shaky and slow before I took it in and was still shaky after. If I don't press any f keys she goes through the logo and start up task bar goes all blue on the task bar and then the screen just goes black. There is no message or cursor arrow.
thanks for trying to help
