I bought a new pc from costco for my wife the other day. I replaced the 300w power supply with a 500w one. Then I tried to add an old GTX 650ti. With the video card installed, nothing would show up on any monitor regardless of which video outputs I tried. The computer is an Acer Aspire (ATC-705-UC52) Is there something I'm missing in regards to adding a video card? Like is there any chance the board doesn't support PCIe 2.0 even???
