My experience over hundreds of such installations indicates this: If your Cat5 cabling was installed by your friendly local electrician, you may find she/he has made the connection incorrectly. You will find that the NICs and the 100BASET switch will indicate that the physical connection is there (appropriate LEDs) but data will fail to be transmitted. Incorrect termination is most easily proved by the use of a 10BASET hub or switch which in almost all cases WILL work over incorrectly terminated Cat5 cabling. 100BASET will NEVER work over incorrectly terminated Cat5 cabling.
