NSIS error, and blue screen restarts.. any suggestions?

Hello, this is my first time posting in this forum. I have a few problems that I cannot fix.

My computer was just assembled.

Symptoms At First:
Ran smoothly for several hours. Seeing that all my hardware had the appropriate software updates to support them. (ASUS updates and NVIDIA updates.. Can not check Windows updates..)

I began downloading files from e-mule. (NSIS error nearly every time. Eventually I established an installer that was not corrupted... Still unsure of what is corrupting my files on downloading.) All the files that I downloaded were put onto my partitioned space. (C:/ drive contains the OS, total 100gb hd, Drive E:/ Storage total 200 gb hd)

I began accessing music files through the Core Media Player, stored on the E:/ drive. At this point my computer began to randomly restart. After a few days of this occuring regulartly I googled it, and the NSIS error.. Found too many results to sift through, so I began running Mallware walkthroughs here on Majorgeeks.com to see if that was the problem. Found a bit of mallware, and several virus's but was able to kill them all on my own.

Both problems kept happening, and keep on happening. So I again googled the random restarts. I disabled the restart on sys error. Now it started bluescreen restarts giving me a Driver_IRQL_Not_Less_or_Equal message.

At this point I followed a procedure that took me to the properties of the my computer tab and told me to auto the virtual memory paging file under advanced performance, so I did.

Still it blue screens me with the same message. Im getting ancy here... A friend of mine thinks that he knows how to fix it, he has a utility I can use, but we cant transfer the file because I continually get that NSIS error message... Any suggestions?

 

Could be the nVidia firewall.
