Alright. I am having a problem with my PC after replacing the card.
Don't know if it's the power supply or the card acting up but at times when my PC is running, everything will go blank i.e. the monitor will get no signal yet the fans will keep on running. Upon pressing the power button, the computer shuts down directly instead of going through the windows shut down process. Either that or it won't shut down at all and I have to force it.
I don't know if the problem is the power supply or the card cause me and my brother have identical PC Setup except for the processor which should have similar voltage requirements.
It's an HD6950 and the power supply is 550W with no overclocking on the processor or the card.
The drivers are up to date (though I don't know if I need to check my BIOS drivers or how to update my card's BIOS).
The ONLY thing I can think of is that the power supply i.e. 550W is not sufficient enough and maybe I need to upgrade.
EDIT: I calculated and 450W should be sufficient enough for my PC... I don't know what am I missing?
Another tidbit: I also get (used to with old card. still do with new card) black screen when I wake my PC up from a long couple hours of sleep.
