Just type about:support in the url bar and a page will be displayed. Scroll down the page and you will get a section named Graphics. Just copy/paste the information displayed there in the bug. Thanks.

Glad I could help. This seems like a duplicate of the bug 919454 . An update of your vga card driver should solve the problem.

Yes it looks like a duplicate of bug 919454.
If so, it seems the faulty driver range is a bit wider than the one recorded (as per https://bugzilla.mozilla.org/attachment.cgi?id=828392&action=edit ): 6.14.10.5076->6.14.10.5160 (exclusive)

So you may want to also record the 6.14.10.5068 version as broken ...
