I purchased a new Toshiba net book NB200-123 3G (operating system XP) last week. Last night I switched it on and it booted up and was loading the desktop page when the screen went blue. I switched it off and then tried to switch it on again. The netbook switches on, you can hear a bit of life and then silence. The ON button remains on and the power adapter light and the battery light but nothing else. Screen remains black. Took the battery off and used th adapter, used the battery on its own but does not help. PLEASE HELP!!!!
