Hi all
Just thought I would post this incase anyone else has come across this a friend said I could have a play with his acer aspireone ZG5 as it was dead well a little googling and I found out what was wrong with it the BIOS was corrupt. All that was happening when it was switched on was the power light would come on but nothing else would happen I initially thought what my mate thought that it was power or the MB but this model has a feature for flashing the BIOS even if you can't boot the machine so long story short I now own this little beauty as I fixed it. Great little machine now running Win7 and it runs Stellarium without a hitch just had to set properties on Stellarium to disable Win7 visual themes and it runs like a dream. Here is the link
