Very strange artefacts with 4850 with furmark 1.6.5

[frabu]

Hello,

When i run Furmark 1.6.5 I get very strange and bad artefacts about 30sec after the begin ot the bench.
The violence and size of the artefacts increase more and more during the benchmark, as shown below.
The artefacts are like flash lights (I mean very short duration)

No problem at all during any daily 2D office tasks

Windows Vista SP1 64bits up to date
ATI 4850 with Catalist 9.2
Corsair 520W







I'm afraid a harware failure on my graphic card...
Thanks for your help
