Guild Wars 2

Ok I know this seems crazy but it has happened to me a few times and i think it might be a driver issue in the end but i just want to see if you guys can help out.
So over the past few months i have had to reformat my computer and reinstall windows due to many issues. They all seem to be issues caused while patching other games. The other games patch fine, but after installing guild wars 2. Then a new patch comes out on steam or planet side 2 needs to patch the client in both cases will lockup the whole computer.
After that I sometimes can or cannot reboot into safe mode, regular windows booting is out of the question.
When it first happened i think i remember somebody mentioning some ‘panda’ or ‘pando’ client that many games use and it helps you download faster or something.

Anybody have any idea what might be happening with these lame details i have provided?
