Windows Explorer keeps crashing

Hey guys,
Didn't see an intro section here to introduce myself so I'm assuming anyone can post freely.

A couple days ago I left for a trip with the family and did my routine shut off and unplugging of all electronics in the house (few years ago a lightning strike while I was away took out my washer and dryer). As soon as I came home and booted up my computer it was apparent something was wrong. After taking 15 minutes to load no matter what I clicked several seconds later an error message would appear saying that windows explorer had crashed leaving my desktop devoid of icons and not letting me do anything. After about 30 minutes windows explorer would reboot only to crash once anything was clicked. I attempted to run malware bytes and super antivirus but nothing would load and after waiting for a while windows explorer would crash once again. I attempted to use cntl+alt+delete to use the "new task" button to reboot windows explorer but as soon as task manager appears, windows explorer crashes. Following the next course of action I rebooted the computer in safe mode along with safe mode only to have windows explorer crash right after I clicked on anything. As a last resort I pressed the "window's repair" only to wait 15 hours and come up with nothing

I don't know if this is a virus or if the problem is with my computer. My computer is only a 1 year old gateway dvt... i5 processor 1tb hard drive, 8gb ram, 3.4ghz processor. Any help would be greatly appreciated, thanks ahead of time

forgot to ask, is there anywhere I can find a windows 7 cd? It didn't come with a cd since it was already on one of the drives but now that I can't get to it, I need to find one
