Installed ASUS PCE-N15 Wireless Adapter now computer won't start

Hello, I installed the ASUS PCE-N15 Wireless Adapter onto my ASUS P8P67 EVO (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard. I have Windows 7 and I BELIEVE I installed it as 64bit. The wireless adapter worked fine for a couple of days. Then I went to turn my computer on and it started doing a system scan and came up with an error message reading like this:

Problem Even

Any help would be much appreciated to solving this problem. Additional info: The computer will not start even if the wireless card has been removed. I also tried to do a system restore but it wouldn't let me.
I also cannot find my Windows Install disk, or else I would just reinstall Windows and start from scratch. I am not very computer savvy so layman's terms would be AWESOME! Thanks in advance!!!!!

This may be related to a corrupt Windows Update more than the wireless driver especially if it worked alright for a few days. Best is to try find a Windows Repair Disk made on another 64-bit Windows 7.

So I can burn the Repair Disk from another computer?

As long as it is the same bit Windows 7 (32 or 64 bit). Sometimes causes issues if done from a non-SP repair disk so make sure you are preparing it on a SP1 PC.

Where can I find the option to burn a repair disk? Sorry... I told you I was quite the non-computer savvy type :)

And thank you for this help!

UPDATE: I got to the advanced boot options and now am on the System Recovery Options menu. I am going to try and find a Repair Disk, but if I cannot, is there any way to fix it from this screen? I was reading something about doing a chkdsk scan or something...?
Thanks!

Yes, you can try the options from the link I gave earlier. Check it out again, most of the steps are done through F8 menu (Advanced Boot Options).
