Fix PCI slots?
Out of curiosity, I decided to to investigate this further, and rebuilt a 10 year old computer that I was pretty sure has working PCI slots, so I plugged in a 56K modem and the questionable WiFi card, and ran the lspci command on linux, and saw the 56K modem, but not the D-link card. Great, so I've got dial up lol! Anyway, there was a huge low dropout 3.3V, 5A AIC1084-33PM voltage regulator that was easy to probe with a multimeter on the dead D-link card, and I suppose it takes 5V from the PCI port and regulates it to 3.297V measured. Too bad this isn't what had failed. That would have also been an easy fix if that all that was wrong.
Now when I move both cards over to my Z77 rig, I notice that there is NO voltage measured across the output of the D link card and ground, indicating pontenially no power to the ports. My guess is that I killed an hair-thin internal trace on the mobo for the power rail, I think this should be an easy fix, if only I knew exactly which pin is what. I do not know the layout of a big PCI bus, or ATX power supply for that matter, and I certainly do NOT want to fry my new (but now old I guess) motherboard! I do however have a motherboard I can cross-reference for pinout. Anyway if I do figure out that the PCI-e slots do actually work, I would like to get a GPU into this rig for general performance improvements, so what <$100 graphics card is recommended?
