windows 7 restarting

Hi

With your error being listed as Java related, just try this

Uninstall Java from Add/Remove, remove all versions you find then run JavaRa (may have to right click it and choose Run as Administrator) then let it clean up any old components of Java, then install and run CCLeaner and run its cleaner and registry options, run the registry one until nothing is listed for removal, then reboot and install the latest Java runtime from HERE (if you have x64 Windows 7 then also install the x64 version linked to in the previous link) but do install and run these in the administrators account and not any if you have them Limited User accounts.

Will also need all questions previously answered as the more information you give the better we can help you, as tech support when you cannot see the physical PC is not always easy,

Is it only when you go on the internet this happens and not in any other application or when not on the internet?

Could try Internet Explorer in no add-ons mode and its in Start > Programs > Accessories > System Tools and see if that connects ok, if it does then you have a corrupt or incompatible add-on installed, and this HERE will help narrow that down, just need to in IE normal mode disable all add-ons and enable one at a time and close and restart IE to find the culprit.

But leaves the questions from earlier on, which can link to a driver issue or temperatures.
