Fed up..........any help greatly appreciated

Heyas all,

Before the last update I had a problem with the dreaded ' black marks' over various parts of my body. For a few days after trying various different methods the problem seemed to rectify itself but now it is back !

I have unistalled SL totally and downloaded again, changed various settings on my preferences, cleared the cache, rebaked numerous times and nothing seems to rid me of this. I have also taken different skin, shapes etc but with no effect.

Please could somebody help me, this is seriously frustrating !

Thanks in advance

Do you know how warm you vid card is?, overclocked? and wich kind -.-

First thought was ati with avatar vertex turned on, that usually make oddities in SL, second thought to warm vid card, i know SL can trip mine to record temperatures.

To high temp/clocked you might get artifacts.
