Now, Problemo numero uno:
Even without the guitar and everything plugged in, the program is making a horrific noise, so I added the noise gate into the chain and that stilled the beast ? what is doing this? Crappy soundcard or what?
It could be the fact that your attempting to run an ASIO application with the native Windows drivers. A Realtek sound card is the on-board sound circuit of your motherboard and runs on the WDM native drivers in Windows. Guitar Rig 4 is primarily an ASIO (Audio Stream Input/Output) application and runs better on a sound card with this facility. Luckily, you can download an ASIO
emulator called ASIO4all at:

This will give your system an ASIO facility and enable you to operate at low latency and buffer settings on ASIO-based software, like GR4. This may or may not, barring any physical faults of the sound card, clean up your signal.

After using noise gate and plugging guitar and amp into mic in the sound still isn't nice and clean like it should come out of the amp (extremely scratchy and and bleigh).
The name of the game here is called "gain staging" or "gain scheduling". All this means is that each component in your chain (guitar, amp, soundcard input) sounds best when they are running at their optimum level. Not all audio device inputs and outputs are calibrated to the same reference level so even though your amp and guitar are running nominally, the output may be overloading the input on your sound card.
What kind of amp are you using? If you are connecting your amp's direct out to the input of the soundcard, make sure that it is not distorting by playing with the output level of your amp until you get a clean signal. If it's a proper, low-impedance mic-level direct output, it should be a relative match to the mic input of your soundcard.
Hope that helps.
Cheers ?
