Hi,

I just bought a new eVGA GTX 660 SC 2Gb graphics card to go into my new build. My CPU hasn't arrived yet so I decided to put it into my existing PC just to test its graphics power in a like for like against my old Radeon X1950 Pro.

Unfortunately, when I put my new card into the PC it doesn't work. The first few times the PC boots up (Windows 8), but the graphics were messed up, lines going down the screen, misaligned lines, random pixel artifacts and whenever I moved the mouse there was a horrible trail of noise being left behind. After the first few times when my PC loads up it never finishes loading, turns my monitor on to standby, and when I reset my PC I get sent to recovery mode.

My first thoughts were some remnants of the old Radeon drivers installed that are conflicting, but I decided to boot directly into my Windows 8 installation DVD and the same graphical issues persisted. I have cleaned the connectors on the new card without any change. I have also changed the PSU to my new Seasonic 550W PSU and still no change.

The motherboard in the old machine is PCI-e v1, whereas this card is PCI-e v3, but I thought all PCI-e cards support older standards so that shouldn't be the issue.

My question is, does this sound like the Graphics Card is dead on arrival, or could it equally likely be just incompatible with my old motherboard? Even though I changed the PSU, can motherboards affect the power going to the card? When I put the old Radeon card back in it immediately worked again. Is it possible for a port to accept some cards but not others, or if the port is on its way out, for one card to handle it but another not to?

I can wait and try it in my new build, but my CPU could be another few days, and if it is defo the card that is screwed I'd rather get it sent back whilst I have time for a quick replacement rather than waiting for disappointment.

Cheers for any advice.

It sounds like a DOA card. Just to do a double-check, try the new card in a different system if you have access to another one (friends', family computer, etc).

Just an update on this issue.

I reinstalled windows on the old PC and continued to have the problem. However, in my new system the graphics card performs fine, I guess it was just a problem with the motherboard, perhaps it couldn't provide enough power through the pcie port.

Anyway, all is working swell. Nice card!

Good to hear there is an end to the issue. I wonder what was the issue with the older computer ?

Really not sure, I switched PSU to rule that out, and thought it may have been conflicting drivers, especially coming from a Radeon card previously, but a complete reformat rules that out. All I could think of was maybe the Mobo simply couldn't handle it, either the fact it was only PCI-e v1, or it just decided it didn't like the card. Just odd because in all my years I've never had a motherboard simply choose to not like a graphics card.

A puzzle that shall elude me for the remainder of my days!

Well, I suppose it serves a better purpose now in your new system. Strange though...
