I recently formated my PC and (re)installed Media Center and also the opera(I use opera due to its session saver). Now when I started opera 9.02 after some 20-25 tabs the cpu uses of opera goes 97-98% i.e. I can not do anything untill I close opera. When I installed opera 9.00 after 10-12 tabs it automatically closes itself. when I restarts opera 9.00 it will start and work properly untill all the webpages are reloaded but after that it again closes itself. Prior to the format I used both the versions of opera and they worked well, then why not now?Is this any virus problem. I scaned my PC with AVG Pro, McAfee 2006, Norton 2007. Before accessing the net my antivirus AVG was updated. Please help me.
