Hello, I have a Trendnet Wireless PCI adapter that is giving me problems. I followed the instructions, installed the software, shutdown the computer and then installed the hardware. I put the card into the PCI slot and made sure it was installed correctly. When I boot the computer up it will not POST. It powers on but nothing happens. I've tried all the available PCI slots and it did the same for all of them. When I remove the adapter the system with POST. Other PCI devices will work fine. I sent the Adapter back for a replacement. The replacement part is doing the same thing. At this point I think that they sent me 2 faulty devices. the IT guy where I bought it thinks that there is an incompatibilty issue. I dont see what can be incompatible, my system is fairy new, pentium 1.0 ghz, lots of RAM, working PCI slots. I never heard of a situation where a PCI card is incompatible with a board that is only a few years old.
