Hi, I have a Sony Vairo- SVE151J13M which after downloading something it has caused several problems that I cannot uninstall or delete. I have tried entering the restore by pressing repeatedly on F8, F10, F12 and even F2 for the BIOS but nothing works, it just ignores me leaving me irritated and back looking at the Windows login screen. If anyone has occurred such problems then do kindly contact me at your earliest convenience please.

Kind regards..... Phil
