"Can't Connect to This Network" Troubleshooting

After much research and testing of other answers found on SuperUser and online I cannot resolve:

• All the devices that I'm connecting to my router are connecting/working normally, except one PC.
• These devices include 3 android phones, 1 MacBook, 1 PC Laptop and two Android tablets. All working without any problems whatsoever.
• The PC that won't connect won't even touch the router and it really pisses me off that I can't solve it.
• I've tried with the winsock reset, driver updates, tried with a wifi dongle, no dice.

Issue

• So, everything seems to go OK, but then system seems to lose the sight of the router even though the signal is super strong (RSSI: 255) and refuses to continue the connection.
