Okay here's a little detail on my problem. Both my Keyboard and Mouse were hooked into the ps/2 ports.

My cursor started lagging one night so I did a trouble shooter and tested my mouse through Windows XP. It came back as working just fine with no errors. However it was still lagging so I rebooted which sometimes fixes those little hiccups. Well when it rebooted the mouse was still lagging for a few minutes then stopped completely. I was able to use my keyboard to tab around and check run another test on the mouse which still came back as nothing wrong. I turned off the computer and changed to a backup mouse I have and turned the computer back on. I was still unable to use the mouse. Then as I was using the tab key to move to my hardware options my keyboard stopped working. I shut down my computer and pulled out my old USB mouse nad keyboard and plugged those in. The USB works fine which is why I'm able to get on here right now.

I even went as far as to unhook the mouse and keyboard and start the computer to see if it would give me an error however it starts right up without any problems.

Any suggestions on how to fix the ps/2 ports?

You could use other bootable disks to see whether your mouse and keyboard work with those OS's, and therefore whether your hardware is OK.
e.g.
1. The Knoppix OS loaded from a Knoppix Linux Live CD (http://www.knoppix.org/).

2. The "Emergency Boot CD" [EBCD] loads its own OS and when you either go to the 2nd menu, or run the "File Manager" you will be asked to OK loading a mouse driver.

Are these a standard keyboard and mouse, or cordless?
Which Windows version?
What makes you think it's the PS2 ports at fault?

Standard Keyboard and mouse. The keyboard is a USB one but I used a converter to plug into the keyboard ps/2 port. The keyboard works just fine when I plug it into the USB port but I get nothing when in the ps/2 port. Both worked fine for years and just recently stopped working just a few minutes apart. They both work fine when I plugged them into another PC to test them.

I use Wondows XP Professional

I was thinking it was the ps/2 ports because if I unplug the mouse and keyboard I'm still able to boot like there's nothing wrong, as if they were still plugged in. However I'm not real computer literate and any suggestions on what else it could be would be greatly appreciated...

How old is your system? Check the mainboard for bulging/brown gunky capacitors around voltage regulators - if something went wrong, the insides of your computer will have a feint, funky smell of burnt chocolate (NOT the characteristic smell of burnt electronics, mind you). Just a single failing capacitor can cause a myriad of system glitches and mind-boggling, random weirdness.

"if I unplug the mouse and keyboard I'm still able to boot like there's nothing wrong, as if they were still plugged in"
Check the BIOS's configuration settings in the BIOS Setup to see that it isn't set for [something like] "Quick POST", or "Quiet Boot", and see that "Halt on all errors" is set.

Why aren't you trying other OS's [Knoppix, EBCD] with their [different and/or functional?] drivers for mouse and keyboard?

The FREE #1-TuffTEST-Lite (http://www.tufftest.com/free.htm) may include tests for mouse and keyboard [can't remember].
It uses its own program code to access hardware directly [no drivers], so only hardware faults can cause hardware to fail tests.
You just Startup with the bootable floppy in the FDD and sit back and watch the tests unless you want to intervene.
