Hello, been a while since i've posted on here but i'm in kind of a bind. I just recently setup my house so that everything is gigabit, all CAT6 cables tested out for 1000mbps and routers and switches are all gig as well. However my main pc has a gig card built into it, a Marvell Yukon 88E8053 PCI-E Gigabit Ethernet Controller but it will only detect 100mbps and even if i force it to 1000mbps it still will only work at 100mbps. When i do force 1000mbps the link lights are completely dead and it's acting as if there is no cable connected, but will work at 100mbps full duplex just fine... I'm at a loss here. If anyone has an idea as how to fix this it would be welcome The driver version is 188.8.131.52 btw.
