When pressing Alt & F10 it freezes with a black screen a underscore in white (like a prompt) and then sort of a rainbow mash line at the top.
When going into Acer ERestore Management it all comes up then at any time within about 10 seconds a blue screen with white writing flashes up real quick (too quick to read).. and the computer shuts down. In safe mode it let us do it all then restarted with no result just a normal restart and no back to factory..
Question.. How can I reset this little computer to factory.
It did get a virus a few days ago and the computer was set to a restore point pre-virus however just to be sure we want to restore it completey...
There is no disk drive in this computer as it's a Acer One netbook. We do have a flashdrive.

This computer has reset to factory once before with no problems using the Alt & F10 method but now it does not work.

Please excuse me I am not very good with computer lingo..

Thank you for any help my apologies if this is in the wrong part of the forum please move to where it should be...
