I have windows 7 64 bit installed as of last night.
Basically when I try to install the PNY GTX 550 TI I get no display. Ive tried plugging into the graphics card withe the DVI cable and into the mobo outputs on both DVI and VGA. I changed the BIOS under Primary Graphics Adapter to PCI with no go and PCI-E got no display either. I think the computer is posting and going to Windows but I'm not entirely sure because I dont have a chassis speaker and the SSD doesn't make any noise (obviously). I don't know if I have to install Lucid Virtu to get the card to work. When installed, the fan on the card spins and the 6 pin connector is in firmly as is the card in the PCI E slot I don't have any other cards installed and only have one PCI-E slot. The display works fine without the card installed, just wont come on without.
I'm running the 1.1 BIOS version. there is and update but I don't know if that is the problem.
Memory has been run through Memtest86+
I have not tried to install the drivers for the card yet. Should that be done before or after the card is installed.
Just tried to install Lucid Virtu. Apparently you need to have the card installed to install Lucid.
Update: Switched The Primary Graphics Adapter to "Onboard" and Ive got display now. I'm going to install the drivers and see what happens. I just checked in the BIOS and its still set to Onboard although the card shows up in the device manager.
Update 2: Changed Primary Graphics Adapter (PGA) to PCI Express and I have display still. Device manager recognizes the video card as it should. I had the DVI cable plugged into the motherboards output and disabled the onboard graphics, everything went black. Switched the cable to the card and went back online. Before that I ran the WEI benchmark and had the same result (6.4 or something). With Intel HD disabled and the DVI plugged into the card its up to a 7.3. I'm going to install and run Furmark and see what that benches at. Then install Lucid Virtu, enable Intel HD and see if it benchmarks the same score.
Update 3: Ran Furmark. The GTX scored a 1444 and around 24 to 25 fps. The Intel graphics were around 200 something and around 4 fps. Big difference. Still trying to figure out Virtu and if I really need it.
Hopefully this can help someone that has the same problem.
