A Bit of Mic Delay, PLEASE HELP
 

Alright, so I've been recording using FL 10 Producer Edition. The grey M-Audio Interface box and A Mxl V63 condenser mic. Everything records fine, except when I'm rapping to my instrumental, I feel like I'm on beat. However when I go back and take a listen, It feels like its off just a tiny bit. I know how I want my music and lyrics to sound, and it's always slightly off. I wasn't having this problem on my friends Mac. I currently have a Toshiba Laptop, Windows 7 PC. In FL 10 I've lowered my ASIO Buffer Size all the way down. I just need suggestions, PLEASE help me. I'm just starting to record my own stuff, and I recently purchased all of this last week.
Any help is greatly appreciated, thank you.

It's latency.
Unless you're game for upgrading stuff and going all pro, the best thing to do is after you've recorded in your situation is to simply zoom in to your vocal take(s) after the fact and chop off the extra space at the beginning and manually move your take left, and just check the waveform and listen to make sure it's lining up correctly.
You should do this without snap-to-grid, which should be a button you enable or disable that either positions your audio to the grid or not. Disable that feature, and chop to your first peaks during a verse or chorus where you know it should line up. Once you have it lined up, you should be good the whole way through.

Thank You, now if I decided to go pro, what would I need to buy? Would a mac be good enough, or would I need to replace all of my equipment?

If you wanted to go pro, you'd be spending thousands of dollars. You don't really need to go that far if you're just trying to fix latency. You just need to have a decent audio interface and a decent computer with a decent processor and enough RAM. Assuming you're not plugging into a mile's worth of cabling and devices, you should be OK. Different DAWs might handle latency differently though, and certainly, different drivers will. Generally, most people use ASIO as their audio driver. You might first try experimenting with different audio drivers to see which gives you the best result.

Currently I use ASIO, I'm not really sure of how to use different ones. I don't think the other drivers pick my mic up.
