I have a dell vostro 200 and I am running win vista 32 bit. I am having intermittent trouble opening either firefox, ie or google chrome and can still open my email programme. I have to restart my computer three or four times to get it going. Even when firefox works I can no longer get IE working. I have norton installed on my computer and I have scanned it with ccleaner, malaware and tracks eraser pro all to no avail. When I started my computer in safe mode, everything worked. When I try to open my browsers, nothing happens, no error messages, nothing. I also tried systen restore but that didn't work either. I am not very tech minded but I hope you guys can help.
