Hi, I am having a problem with my Acer x130 running Vista It has been working fine until recently and I experienced a system crash. The computer will power up but does not see my hard drive even though its recognised in bios. I have pulled the battery out to force a reset, I have adjusted bios, I have checked bios settings against another (Identical) machine that is working fine. I have fitted another Sata drive with XP installed. All to no avail. The system seems to boot but then will attempt to start windows before flicking through a blue screen to reset the display to show 'no signal'. I sometimes get a screen that asks to start repair or boot normally. neither function works and the repair function returns me to an earlier screen. I have checked the sata drive (vista) in another machine and can access it so the data is intact. I have tried everything that I can think of and am now at wits end! help!!
