Here's a some things to try. Double check that both sides of the link have speed and duplex set to autonegotiate. Per the IEEE 802.3ab autonegotitation is mandatory for gigabit. Hard-coding both sides *may* work but is not to standard and is not recommended. Hard-coding just one side will not work.
Check the cabling. Gigabit can be touchy about cabling. Is the cable run between the PC and switch especially short? (Less than 1 meter) If so, swap it out for a longer cable. Is it really long? Shorten it up. Are you using CAT5E, 6, or 6E? Try plain old CAT5. Swap out the NIC in the PC.
