I got a new MSI HD6850 and it is acting a weird. The graphics card has not been overclocked and the temperature is normally at 50 °C. I also have have XFX 6850 and that one works fine.

My first suggestion would be to get a more powerful PSU.
330w is low for the overall system requirements.

Well I had 6850's before and they didn't behave like this one. Just becuase the voltage is too low doesn't mean I'm going to get weird lines and BSOD

It's your power supply I can bet on it 330w is way to low im surprised you got your rig to even post

Besides that trying to run your machine on such low wattage psu your looking to damage something most likly the card

If you look on your box you need nothing short of a 500w supply but if you dont belive me keep on going with it and eventually it will take everything with it

I run 2 hd6870 in cross fired i was maxing out my 700 w PSU because of my OC and other devices hooked up I in turned went for a much bigger psu and it helps keep everything in order

Next question you said you ran them before meaning you already went through a couple ?

Crossfire needs 600w BTW
