Well, nothing I can think of that would remedy all the diagnosis you provided. For example we can try a MAC Address change (I am still assuming wired and wireless has different issues).
Get Win7 MAC Address Changer v2.0 and try to change the MAC address of the ethernet adapter (last 2 digits) to 01 and 02, respectively. Note that some NICs don't allow MAC address changing. Hopefully yours will.
Perhaps you should also check your RAMs and CPU.
- RAM - Test with Memtest86+
- CPU: Intel Burn Test and/or Prime95
- Just saw you got 2x770s - try disabling SLI too
