I have had an ASRock board for several years. Started it out with an AGP card and then moved to PCie nVidia 8600 256mb (supports AGP & PCie). Works well. However, The ASrock board only has a 4x PCie slot! Since I am always behind the hardware curve I decided to get up to PCie 16x. Well got a Gigabyte board but no display. Next an Asus board same thing. Now I just tried a newer ASRock board but will not even post with 8600 plugged in. Putting everything (CPU, Memory. 8600) back in the old board and it works well. I am quite confident that the problem is the 8600 since on the new ASRock board I booted up without the card plugged in and I had a series of beeps which did not happen with it in. The other boards beeped to signal video card problems.I saw one old post that mentioned the 8600 used PCie standard 1.6 instead of 2.0. If true could this be the reason for three different boards rejecting it?Any other known issues with the 8600?

The PCI-E standard is backwards compatible, so cards that were built with the original PCI-E standard should work just fine on boards designed with the PCI-E 2.0 architecture.Sounds like there is a physical problem with the card at the connection point. I suggest RMAing it.

The problem occurred on three different motherboards. Either I stay with present setup or try a new video card. Ordered a GTX 240/512mb. Even have a nice new 750w power supply from Antec since that is the other common part. Display not involved since no boot with/without display.
