ACER Aspire AOA150 Netbook not booting properly. Caught in a vicious cycle, where the WinXP screen displays on screen, following by a quick view of a blue screen, then back to the boot options. Tried all options - Safe Mode, SM with Networking, SM with CommandPrompt, LKGC, Start Normally - but ends up on the same page. Any ideas how to fix this? Thanks in advance for your help.
