Advent Vega Dropping off web page

[Guest skercat]

Hi, I hope this is the correct way to use this forum.

I have an Advent Vega with Modaco installed.

Since the battery ran below 10% capacity, I am having trouble connecting to some web sites, e.g. Hotmail, ebay. The connection begins, with a yellow line at the top of the screen displaying progress. As soon as the yellow line has gone right accross the screen, the system drops out back to the home screen.

I have reset the system and installed a virus checker.

Are you able to point me in the direction of some advice please?

Many thanks

Sue
