Guild Wars 2

Hello,im playing gw nearly 6 months on lowest graphics specs without major problems altough I had occasionally random crashes saying “out of memory”.My PC spec is:
Intel core i5 750 2.67GHz
GTX260
4GB RAM
Windows 7 32bit Ultimate
While trying to scale my grpahic up a bit(by pressing auto-detect),I suddenly having random rainbowish colors blocking my minimap or even my screen and sometimes when I press H my character is rainbowish colored…and most of the times I eventually get crashed.
When I tried to make screenshot of the problem I got crashed again with 2 errors:

up,pretty much cant play…

up,please help O.O

same problem, and no one answering

I’ve seen some peeps fix the rainbow of colours (blues/greens) by uninstalling video card drivers, downloading and re-installing the newest drivers from the website. Try that and if it doesn’t work, file a ticket (see the sticky), then post the fix here for others.

I just did it and still failing
got this now:
