I have 5 computers at my disposal and multiple switches.

2 computers cannot ping one another.
Same subnet of 255.255.255.0 and IP's of 192.168.0.1 and 192.168.0.2. I also introduced two other computers as 192.168.0.3 and 192.168.0.4.
No computer can ping the other.
W7 Pro. Why am I doing this? All of a sudden the media center fell off of the network.
I've tried this scenario with 2 other known working switches.
