Explorer shutdown when opening folder on Iomega external drive

I am having some crazy issues with my computer. I had a plethora of BSOD's which led up to my computer crashing completely. I reinstalled windows by deleting the partition and putting it back on fresh and new but had to do it twice since the first time didn't work.

The first time gave me hell after I tried to drag my saved music files for itunes onto my new desktop. This led to the Explorer restart issue which was so bad that I just reinstalled the system again. I have had the system up and running and everything seems OK (lag in speed since I took out two of my 2 GB memory sticks after thinking they might have been the problem-PNY is sending me replacements) but now I am noticing that I am getting the EXPLORER HAS SHUT DOWN error when trying to open my folders on my Iomega drive. I have done a scan disc on this hard drive and it is totally free of errors. No errors have been found. The External drive is only about 7 months old. I have scanned it for viruses with AVG Internet Security 2012 and it has no viruses to my knowledge.

What can I do to save this drive??? I have almost 1.3 gb of important stuff on it!!! Help!!! I am not very computer savvy so this is really mentally exhausting and frustrating. I am thinking of getting a new system but I am scared something is up with the external drive that might ruin my NEW system once I try and put it on there.

ALSO, I should mention that my external drive folders open fine on my laptop...so, that has to mean something right? Hmmmmm. I'm so confused!!!

Please respond!!
