Okay so heres my situation, I currently have Window Vista Business 32 bit. I cannot open any folder with out my Explorer crashing and me having to manually start explorer again. I think it was some thing to do with a Trojan that's currently embedded itself in the System 32 files. I was wondering if a reinstall of the OS would fix that. I was also wondering if I can reinstall the OS with out loosing the 205 GB of data and games that on my HD (no partitions at all).
My
(basic) Specs:
Nvidia 8800 GTS
AMD FX-62 2.8 Dual Core
4GB Corsair ram PC6400 800MHz
I really want to got the 64 bit version to get full access to my 4GB of ram. I was wondering if if that potentially could cause a problem..... beside compatibility.
