Chosen Solution
I was wondering if the graphics card could be updated. I have the NVIDIA Geforce 7300 128 MB but I would like to upgrade to the 256 MB. Is this an easy task? Will this cure the problem as I have seen A LOT of the message boards saying this is the issue with this particular brand? Where can I buy if this is the case. Thanks!!
