I had my computer crash last week during a power outage, when I got back home I fired it up and my anti-virus (Kaspersky internet security) was not running and would not run, i tried updating it several times with no luck. So I then figured I would restart the computer and hope the problem worked itself out. During restart I got windows could not start missing or corrupt system 32 something or another. I ended up giving my comp to a friend to have him look at it. He ended up installing win 7 and all my old program files, pics, music, videos etc. were in a windows.old file. I couldn't get my programs to run because they were missing files etc. so I started cleaning up the drive deleating everything except the personal files. my friend recomended Bittorent for p2p filesharing, instead of limewire which I was using before. So I downloaded bittorent and tried to download a torrent file, the file did not start downloading and quit responding. I restarted the computer and windows would not boot. It would try a system recovery and nothing would work. It did not recognize there was an OS installed on my harddrive. My drive ended up getting wiped clean. I reinstalled the OS and started over. Two days the system was running flawless, last night I downloaded bitorrent again and the same thing happened. So here I am with a fresh system again, what could be going on? Anyone else have this kind of issue? I am using the win 7 iso download with loader program to activate. The harddrive is clean, but i am beginning to question the drive now, i have had this happen atleast 4 times, formatted the drive reinstalled win 7, activated it, and started reinstalling programs etc. only to have it fail to boot when restarted. Any help would be appreciated. system is custom. asus m3a32-mvp mobo amd phenom 160 hd 500 hd 4 gig ram the hd i am beginning to question is the 160, the 500 is empty, i was going to try using that drive on my next attempt. i have nothing to loose now but my sanity. i'm just wondering if i am doing something wrong.
